Forschungsprojekte

The project PreMainSHM aims to raise the area of preventive structural health monitoring (SHM) to a new level of networked systems. This applies not only to the networking of self-sustaining sensors and their sensor data, but also to the networking and utilization of relevant information for the building condition assessment and building management. The main aim of the project is to further develop existing components in the interaction of the various systems for exemplary application scenarios and to integrate them into a cloud-based, scalable, but also highly efficient and interoperable system. The starting point for further developments is provided by the applicants’ existing technologies as well as their existing know-how in the field of wireless sensor networks and fiber optic systems. The proposed monitoring concepts are based on a separation into passive, embeddable sensor components and exchangeable measurement electronics. The aim is to provide cost-effective, robust, embeddable sensors based on electrical measurement principles that can be calibrated if necessary, for permanent installation on the building and to combine them with distributed fiber optic sensors (DFOS) in a complete monitoring solution. In order to obtain information relevant to the building management, suitable analysis and prognosis procedures are being further developed, adapted and evaluated with the aim of on-site data cleansing and simultaneous data reduction and data fusion. In addition to model-based algorithms, artificial intelligence (AI) methods are used and integrated into an interoperable software framework. The latter enables the status information to be displayed in the form of a digital twin via web user interfaces, as well as the integration of the status information in building management systems via other interfaces.

The project COOL-QUARTER-PLUS was developed to counteract the current trend towards inefficient individual units with coordinated cooling concepts at neighbourhood level. The focus is on office and research quarters, because here central measures are more likely to be implemented than in heterogeneous residential or mixed-use quarters due to the ownership structure and central management.

High-resolution Luminescent Analyses of Construction Materials The pH and chloride content of concrete-based construction materials are key parameter for the assessment of their stability and long-term performances, since major types of chemical degradation mechanisms such as carbonation, chloride induced steel corrosion, as well as leaching and acid attack are strongly associated with a change of the latter. The aim of this project is to explore luminescent analytical methods as an advanced technique for the measurements of pH and chloride on and in concrete-based materials in order to determine the state of repair of concrete constructions and to increase the understanding of ongoing corrosion processes. The main goals can be summarized as follows: - Target-oriented development of high-resolution imaging system for pH, chloride and potentially further relevant ions (e.g. potassium and calcium). - On-site application of the measurement method as a simple, fast and economical analytical tool for the state-of-repair of concrete infrastructure (e.g. miniaturized probes and/or sensor particles). - Improvement of the process understanding of important alteration processes in concrete and elaboration of recommendations for applications & material developments.

CARBAFIN will develop, based on an integrated biocatalytic production technology, a radically new value chain for the utilisation of surplus sucrose, estimated to exceed 300 kilotons/year as of 2019, from sugar beet biomass in the EU. CARBAFIN will demonstrate bio-based co-production of a functional glucoside and fructose. The glucoside products of CARBAFIN have large-scale uses in nutrition and feed, cosmetics and detergents (≥ 100 kilotons/year). Fructose is exploited in the production of 5-hydroxymethylfurfural (HMF), a versatile chemical building block currently considered for making bio-based plastics. Leading platform technologies in biocatalytic cell factories and downstream processing, conjointly optimised in CARBAFIN for performance efficiency and cost-effectiveness under full integration of LCA and economic evaluation, are key to make industrial co-production of glycosides and HMF via fructose competitive in today's markets (≤ 5 € production costs/kg). In addition, CARBAFIN contributes to the establishment of new, fully renewables-based value chains across the European industries, linking the sugar industry sector to the cosmetics, chemicals, polymer and detergents sectors and strengthening the sugar industries' role in food and feed. It supports the efficient cascading use of sugar beet-derived sucrose in combination with biomass-derived base chemicals (e.g. glycerol, glucose). CARBAFIN's HMF production aims at replacing petroleum-based chemicals with bio-based building blocks. CARBAFIN will thus contribute to development of a chemical industry that is low-carbon, resource-efficient and sustainable. CARBAFIN will help Europe to maintain global leadership in industrial biotechnology and secure position as innovation leader in sugar-based products. CARBAFIN's innovations will involve broadly the engagement of societal actors with particular emphasis on consumer awareness and acceptance.

In the “UpcycSlag-Binder” research project, the fundamentals for the provision of new, sustainable binders for mineral building materials made from residual materials and supplements are to be researched. An interdisciplinary consortium made up of the scientific partners Montan University Leoben - Chair for Thermal Process Technology (TPT) and Graz University of Technology - Institute for Materials Testing and Building Material Technology with TVFA (IMBT) will work together with regional partners. The present project aims at making previously dumped metallurgical residues usable by means of suitable treatment, cooling and processing steps and by combining them with other secondary raw materials. For this purpose, the necessary process engineering fundamentals as well as the binder effectiveness or reaction mechanisms are explored and the properties or characteristic values of the new, sustainable binders are evaluated with regard to technical performance, CO2 emissions and recyclability.

Preventive conservation (PC) has emerged as an important approach to save and ensure long-term health of sensitive cultural heritage (CH) movable artefacts currently displayed in inappropriate environmental conditions in small and medium EU museums. The aim of SensMat is to develop and implement innovative, low cost and user-friendly tools, including a decision making tool, with recommendations and guidelines for museum management and staff in charge of collection preservation. SensMat methodology will combine the results of a preliminary survey involving SensMat advisory group and relevant stakeholders’ feedbacks (cultural institutions, regions, certifications organisms, academies, museums, industrials) and include 8 WPs driven by a consortium with strong capacity to provide a new preventive solution achieving a TRL 7 maturity. SensMat concept is built around new sensors systems that monitor collection environments and continuously assess specific materials degradations. Based on multiscale modelling, data management systems, collaborative platforms and sensor communication networks (IoT), museums stakeholders will be informed in real-time of possible dangers to their artefacts, thus reducing degradation risks and costly conservation treatment. 10 representative case studies in museums , historical buildings, storage sites and workshops ((in Denmark, France and Austria), knowledge transfer, specific trainings, and recommendations of best practices will facilitate standardization, strategy implementation, new policy definition, and finally adoption of the new PCCH solution by all CH stakeholders.

Microbial induced concrete corrosion (MICC) is accounted for ~40 % of the degradation of concrete based subsurface wastewater infrastructure globally. A further problem is the toxic outgazing, which poses a serious health hazard. In Germany a use of 450 Mil. Euro for repair measures of MICC-damaged sewer systems are documented each year. The number of unreported cases is suspected to be significantly higher. At present there are two usual ways, how to repair such sewer constructions: Firstly by mounting inliners made from plastic and secondly by coating the inner surfaces. The latter is mostly realised by the use of organic polymer-modified mortars and synthetic resins (i.e. epoxy). A great number of such measures of repair turned out to be costly and non-durable. This is the reason why alternative materials, especially inorganic ones based on the silicate-technology, were developed and launched. These materials are used for making very thin (up to 3mm) coatings. Their long-lasting protective function has not been proven yet. Conventional sulphate attack happens via fluid transport whereas MICC progresses due to the transport and diffusion of aggressive gases such as H2S and CO2 and subsequent microbial transformations. Thin coatings from silicate-based inorganic materials are generally water-proof but permeable to gas and therefore they cannot sufficiently work as a MICC barrier for the standard concrete beyond. One of the most acid-resistant silicate-based materials are Geopolymers. However, their physical and microstructural properties vary in a wide range depending on their composition. If Geopolymers are mixed with aggregates, one gets Geopolymer Concrete (GPC). The project consortium developed specific compositions of GPC, highly resistant against MICC. Further previous research work pointed out, that certain metallic admixtures significantly inhibit the growth of relevant bacteria steering this highly corrosive attack of concrete. Based on these findings the outlined project BioResComp deals with the idea to use such innovative bacteriostatic Geopolymer Concrete as a more solid construction material instead of thin coating applications for both, repair measures and new construction of waste-water buildings. One can expect that constructing without any standard concrete will not be an economic future way. Therefore, the project proposes a new composite technique by combining a standard concrete part with a GPC part. The key of this technique is a very strong bond between the two materials. Main goal of the project is to study the mechanical composite behavior and the resistance of composites to MICC. A multi-disciplinary and mainly experimental research approach will help to get a comprehensive understanding of all the interdependencies between material composition, GPC-thickness, bond behavior, crack formation, bacterial growth and the corrosion mechanisms. We follow the hypothesis, that at certain thicknesses of the new bacteriostatic GPC layer (typically a few centimeters) a balance between the microbial growth (attack) and the corresponding resistance of the composite system will come into being.

The IEA EBC Annex 72 therefore concentrates on the harmonization of assessment methods on construction-specific and operational environmental impacts (primary energy demand, greenhouse gas emissions and other indicators) throughout the entire life cycle of buildings. In order to support the applicability of harmonized methods in buildings design, the integration into digital design and planning processes is examined as well as the development of guidelines on building level based on numerous international case studies. For participating countries, which do not yet have any regional, construction sector-specific databases, the development of these is to be supported.

The project UniNEtZ Universitäten und nachhaltige Entwicklungsziele (translation: Universities and Sustainable Development Goals) wants to strengthen this role of universities in Austria. The interdisciplinary project, involving 17 universities at present (August 2018), aims to build up cooperation between universities in order to work on the SDGs in a more targeted manner. The scientific basis for guiding political decisions and for developing meaningful measures for SDG implementation will be provided by the participating universities in order to support achievement of the SDGs. In order to build on existing expertise, it is important to know the status quo of available sustainability research. During the past months, we have been working on a digital map of research activities related to sustainability topics, based on the definition of the SDGs. The aim of this approach is to identify current focus areas as well as underrepresented research fields related to SDGs to provide universities with a basis for targeted sustainability research. The results are directly integrated into the activities in the frame of the project UniNEtZ.

The intended research is to be used for future decisions on the further development of hydrogen from methane. An LCA of carbon - Life Cycle Assessment - will evaluate the various uses of the solid carbon produced, as well as describe the use of carbon in agriculture and construction, and the resulting properties of building materials and fertilizers. In electrolysis, the energy required for the electrochemical splitting of the water molecule accounts for the largest share of the total CO2 footprint (besides the electrode material). Energy from renewable sources can therefore make a significant contribution to reducing the CO2 footprint. In the case of pyrolysis from methane, the share of energy is significantly lower (thermodynamically only about 1/8 of electrolysis), but the raw material also has a certain CO2 footprint

The objective of the project is to develop and implement a scalable temporary and post utilization concept for the brownfield sites. This should enable interested people to permanently or temporarily experience, shape and implement the green infrastructure in their district as a central climate change adaptation measure in cities. For this purpose an innovative demonstration building will be constructed as an example of a temporary use (green.LAB) on the brownfield area in the Smart City district. The green.LAB is a further development of the Urban Boxes of Energie Steiermark aiming at development of a transportable modular timber construction combined with green building concepts, biodiversity, district garden, rainwater management as well as efficient energy supply and the use of renewable energy sources. The green.LAB will be open to different target groups (neighbors / citizens, developers, investors, schools, businesses, administration) as a low- threshold, open learning, working and exhibition space for all topics revolving around urban green as well as a meeting point in the city district. It should be also temporarily used as the office of the district management. The green.LAB as a demonstration building with an innovative temporary-use concept should be scaled up in different urban development areas after the completion of the project. Moreover, concrete usage scenarios as well as use cases, including business models for the “green urban boxes” will be developed and evaluated

In order to achieve the climate goals, sustainability is becoming more and more relevant in all sectors. Due to the long-term cost effects of the operating and maintenance costs and their technical systems, a life cycle-oriented approach is therefore an advantage, especially in infrastructure construction. With the dynamic life cycle costing (a method from the classical investment calculation) a so-called capital value is determined, with which variants with respect to their costs under consideration of the time value of the money can be compared with each other.

The objective of this research project is to provide the essential fundaments for a product-related substitution of steel materials by Ultra High Performance Concrete (UHPC). This represents an essential contribution to sustainable construction because steel is significantly more intensive in terms of cost and CO2 emissions than UHPC. Further, raw materials available in Austria and the micro steel fibers of company Voestalpine CPA Filament GmbH will be used. To achieve the goal of this project, in addition to the development of materials, questions about some basic issues such as the introduction of the prestressing force in thin UHPC components, the bond between normal concrete and UHPC, the connection between UHPC and steel, the confinement effect of UHPC by steel reinforcement and the shear capacity of thin-walled prestressed UHPC panels will be answered. For this purpose, detailed studies using non-linear finite element modeling, engineering models and model experiments are planned. In addition to the investigation into the mechanical relations, studies for the production technology are also scheduled. The results of the basic research should be verified by laboratory tests to demonstrate the basic feasibility of this idea into practice and also to achieve the first reference values for an economic and ecological assessment in terms of product development in further research steps. The productions of the structural components and the tests will be carried out at the precast plant of Kirchdorfer Fertigteilholding GmbH. The consortium consisting of TU Graz, FH Kärnten, Kirchdorfer Fertigteilholding GmbH and Voestalpine CPA Filament GmbH has high competence in various fields. Through mutual complement the best requirement for a successful implementation of the proposed research project is created.

The technology of the shotcrete in tunneling and underground mining has in Austria in connection with the "New Austrian Tunnelling Method" NATM a traditionally developed over the years with a high quality standard. Austrian companies are leaders in your application and thus successful international. Today new demands are in the foreground, especially a few years ago often underestimated (aggressive) environments in tunnels will increasingly lead to earlier than expected damage anddurability problems. Of which is affected not only the shotcrete, but the entire structure. This means for the operators and users of underground infrastructure constructions (tunnels, galleries, shafts, piping, etc.) are increasingly difficult to calculate risk, to invest limitations in the availability and in case of damage in a very costly repair measures. The technical objectives are the development of shotcrete with high durability, both for repairs and for new buildings. In this resources should be used efficiently and stustainable the context of sustainable development and climate change. This object is combined by the term "ASSpC - Advanced and Sustainable Sprayed Concrete". To achieve this overall objective, it is first necessary to develop recipes, in intermediate steps to put them into spray tests and parallel to define test method for assessing the durability as well as to investigate basic response and damage mechanisms. They may not depart the robustness of the mixtures in the application, nor the high propulsive power are endangered in the tunnel.

Ziel des vorliegenden Forschungsprojekts ist es, Beton für Fertigteile hinsichtlich seiner Zusam-mensetzung grundlegend zu verbessern, sodass sein Treibhauspotenzial (CO2-Emissionen) sowie sein Ressourcenverbrauch gesenkt werden. Der verbesserte Beton soll eine gleichbleibende Festbetonqualität im Vergleich zu Normalbeton nach Norm sowie eine produktionsorientiert hohe Frühfestigkeit aufweisen. Betrachtet wird von Anfang an das Fünfstoff-System Beton (Zement, Wasser, Gesteinskörnungen, Zusatzstoffe und Zusatzmittel) unter Berücksichtigung der speziellen Erfordernisse der Betonherstellung in Fertigteilwerken. Durch eine Optimierung der Packungsdichte aller granularen Ausgangsstoffe von Beton bis in den Feinst-Teil-Bereich hinein (bis etwa 100 nm) verbunden mit einer Verringerung des Wasserbedarfs soll Zement (bzw. Portlandzementklinker) der die Hauptursache für das hohe Treibhauspotenzial von Beton ist und auch einen Hauptteil der Kosten ausmacht durch kostengünstige, in Österreich verfügbare und umweltfreundlichere Stoffe substituiert werden. Die Bindemittelgehalte sollen durch betontechnologische Maßnahmen auch unter derzeitige Min-destbindemittelgehalte nach Norm gesenkt werden. Es bedarf gewisser Änderungen der Herstel-lungspraxis der Betonfertigteilproduktion und einer Überarbeitung des Regelwerks bezüglich der Reglementierungen der Betonzusammensetzung (i.e. Mindestbindemittelgehalte). Es ist nachzuwei-sen, dass die in ihrer Zusammensetzung optimierten Betone hinsichtlich Festigkeit und Dauerhaf-tigkeit bzw. Beständigkeit gegenüber Umwelteinwirkungen eine gleichwertige Leistungsfähigkeit aufweisen wie Betone nach derzeitiger Norm. Zudem müssen spezielle Anforderungen an Beton für Fertigteile erfüllt werden können: Das sind hohe Frühfestigkeiten, gute Verarbeitbarkeit, entsprechende Oberflächenqualität sowie die Robustheit der Mischungen gegenüber Produktionsschwankungen. Nicht zuletzt soll gezeigt werden, dass sich die ökologische Bewertung der Betone durch eine neue Zusammensetzung substantiell verbessern lässt und sie wirtschaftlich herstellbar sind.

The holistic life-cycle-oriented consideration of construction activities develops into a mega trend in the construction sector. The UNAB project aims at the "Implementation of sustainable construction through optimized project management processes and integral building envelopes” by an interfaculty and interdisciplinary cooperation between Graz University of Technology and project partners from industry. Operationalizing sustainable construction two different approaches will be investigated. The first approach follows the idea of systems engineering focussing sustainability requirements of planning and project management processes. Current planning processes mostly focus on single sustainability aspects like energy efficiency, reduction of environmental impacts or reduction of life cycle costs. According to the upcoming CEN/TC 350 standards the evaluation of buildings sustainability should include, environmental, social and economic as well as functional and technical issues, preferably already in the planning stage. Early estimations of the expected buildings sustainability lead to the need of appropriate tools that allow both, the consideration of sustainability aspects including their systemic affects as well as the identification of the influence by different stakeholder preferences. Henceforth the knowledge about system interdependences of building optimization processes should provide basic information to influence building sustainability regarding a holistic approach. The second approach aims at the design implementation in the building envelope. The main focus is laid on materials that combine variety of cross-section design, easy disassembly (with suitable joining technique) durability (with proper choice of material) and maximum recyclability. The new façade concept should combine a self-supporting, highly efficient supporting structure with new methods of forming and joining technology from the mechanical engineering sector as well as the integration of building systems in the building envelope. This represents a major challenge for the implementation in the field of design, static, building physics and equipment-related issues which only can be solved by a close interdisciplinary cooperation between the disciplines involved. So-called "Integral facades" influence a variety of socio-functional and technical as well as economic and environmental assessment criteria of a building. Thus they are best suited to improve the overall building sustainability. Based on the interaction of both approaches the results of this project should provide project owners, planners and project managers with basic information needed for a holistic life cycle orientated planning process.

The ambition of this fundamental research project is to develop the entire process for the realization of a uhpc-shell structure made of precast-elements, reaching from the design to the fabrication. All issues are dealed by an interdisciplinary team of architects, structural engineers and material scientists. In addition to that business partners from different kind of industries are supporting the intention. One part of the project is the development of adequate casting-methods for thin-walled shell elements, considering material properties of uhpc (ultra high performance concrete). Another issue is the design of different suitable joining technologies. Furthermore is the digital parametric design of shell structures and the engineering of a flexible formwork, actuated by an industrial robot a substantial part of the project.

The mechanisms of sulphate can vary due to different conditions (ettringite and thaumasite formation). Thaumasite forms at low temperatures and a source of carbonate is needed. It causes damages in the cement matrix, which will lead to a mushy substance. The standards include only volume expansion due to the formation of ettringite or gypsum. But it is not included how fluctuant sulphate concentration should be evaluated. The treshold values of sulphate concentration are assumped under constant conditions. Specimen were made and stored in different sulphate solutions (constant level and fluctuant level) in the laboratory. Other specimen were stored in a waste water sewer to get a practical aspect. Those examinations should give a view, what kind of the influence fluctuant sulphate concentrations have and which sulphate concentration is needed to be harmful

The project "iENERGY Weiz-Gleisdorf 2.0 the power of a vision!" is built on the energy vision 2050 of the energy region Weiz-Gleisdorf. It is the aim of this project to visually anticipate this vision in form of single demonstration projects, i.e. public visualization of visionary complete solutions within the context of "Smart Cities" or "Smart Urban Regions", renewable energy, energy efficiency and regional energetic autonomy. Complete sustainable solutions arise mainly from the involvement of citizens - the use of innovative technologies or their integration into intelligent products and services and their user-oriented demonstration are important stimuli for the energy awareness, both on group and individual levels. Thus, this project is an important building block for an accelerated development of the energy region towards its vision

The aim of the current research project is the identification of environmental indicators, which should be taken into account to assess and quantify the environmental impact of buildings and building products. In this project the indicators, as also the common LCIA-Methods, which are integrated in the EN 15804 at the moment for the construction sector should be adapted and developed further with additional indicators to build an essential basis for the ecological optimization of building products. The need of an further development of environmental indicators is given in the fields of land use and soil sealing, biodiversity as also human – and eco toxicity. In those areas the scientific point of view haven’t been considered in detail. The analysis of the different additional indicators should show the relevance for the construction sector, as also there should be shown the quality, robustness and the availability of the environmental indicators and the LCIA-Methods. As an result there should be identified suitable methods to show the priority of the environmental indicators. Furthermore the results should be a basis to supplement or revise the EN15804, as also to define the core indicators for NAD ÖNORM B 15804

Schwerpunkte der Literaturrecherche sind Publikationen über derzeit angewandte Bauwerks-Management-Systeme für Budgetplanung auf Netz-Ebene sowie Modelle zur Bewertung der Dauerhaftigkeit und Zuverlässigkeit von Kunstbauten. Ausgehend von der derzeitig praktizierten ingenieurmäßigen Zustandsbewertung von Bauwerken gemäß RVS 13.03.XX soll künftig eine genauere Abschätzung der Rest-Lebensdauer von Kunstbauten möglich sein, um eine Optimierung aller erforderlichen Erhaltungsmaßnahmen mit einer vorgegebenen Budget-Obergrenze durchführen zu können. Ein umfassendes Bauwerks-Monitoring wird derzeit nur für Schlüsselobjekte angewandt, wobei der Ansatz verfolgt wird, diese bauwerks- und standortspezifischen Informationen für die Dauerhaftigkeitsbewertung für vergleichbare Bauwerke zu nutzen.

This project deals with the implementation of a quality management system in asphalt mixing plants. The demands for bituminous mixtures are fixed extensive with requirements in technical specifications and standards. The results of the tests are compared with the requirements. If the test result is outside of the tolerances, it will come to deductions or waste. If the existence of non conformities is not discovered, the non conform product will cause follow-up costs for the placing of bituminous mixtures or can lead to a negative inspection for the final product "road". The later one realises non conformities the higher the follow-up costs will be. Therefore, companies look forward to set steps to secure the quality of the bituminous mixtures and further the quality of the road. This project also makes use of the results of the research project "factory production control according to the new prEN 13108-21". The aim of the project is to work out a quality management system for asphalt plants with the necessary statistical methods. Finally the created quality management system shall be tested by implementation in an asphalt mixing plant.

Special attention concerning the use of interior insulation is given to the expected formation of moisture in the wall cross-section. Attempts were made to tackle this situation by means of a wide range of vapour barriers, but it soon became clear that branch lines and openings for building sections and deformations (e.g. wooden joist ceiling beam ends) pose a problem that is difficult to solve. Additionally the Glaser method provides an inadequate description of hygrothermic processes in the wall as it does not allow for capillary moisture transport in the various building materials. Based upon international research findings and a precursor HdZ-project the aim of this research work is to further develop conventional recycled paper cellulose flakes to create a sprayable, self-supporting, 3 - 8 cm thick body of insulation to be covered with an interior spray-on plaster that is open for diffusion. The aim is to avoid harmful water vapour condensation by taking advantage of the high sorption capacity and capillary conductivity of the cellulose fibres and to provide a failure-tolerant, inexpensive alternative to existing insulation systems, particular with regard to the renovation of existing (historically valuable) buildings (02/2003).

If reinforced concrete contains chloride ions, e.g. due to the use of deicing salts, the reinforcement is no longer protected against corrosion. Nitrite salts are in use as corrosion inhibitors. As only nitrite ions dissolved in the pore solution of the cement matrix and not the ions bound in cement can inhibit, it is of great practical relevance to study the degree of nitrite binding in cement and the influence of chloride ions on it. Results show that nitrite ions are bound in cement to a certain degree, however to a lesser extent than chloride. In case of the simultaneous presence of both, chloride and nitrite ions, nitrite binding is further reduced. This is proven by pore solution analysis of cement paste samples prepared with the addition of nitrate or chloride and of both (NaCl and/or NaNO2). The nitrite concentration in pore solutions of the samples containing both salts is demonstrated to be higher than in comparable samples prepared with the addition of nitrite only.

Corrosion inhibitors recommended for subsequent application onto existing structures are a kind of repair material which is cost-efficient and easy to apply. According to the manufacturers, these substances penetrate very rapidly, however, the mechanisms which are responsible for fast migration and involved in transport (capillary suction, diffusion in dissolved state and diffusion in the gaseous phase) have not been sufficiently investigated so far. The major part of the study therefore focuses on the transport of the corrosion inhibitor SIKA Ferro-Gard (FG 903) in cement paste and concrete. It contains two active ingredients, namely a phosphorous compound and an aminoalcohol. It has been shown that the phosphorous compound forms an insoluble salt with the calcium ions of the cement and, therefore, does not penetrate from outside into the concrete and cannot develop an inhibiting effect there. The aminoalcohol, on the other hand, remains largely dissolved in the pore liquid, thus providing optimal conditions for high mobility. The analysis of the transport mechanisms involved has revealed that diffusion in dissolved state is by far the most efficient transport mechanism. While basically transport of the aminoalcohol via the gaseous phase is possible, it plays an inferior role only. Surprisingly, the substance is hardly absorbed by concrete by capillary suction, but remains close to the concrete surface at first.

The use of secondary raw materials (fly ash; residuals from industry, etc) as well as additional sources of energy such as old tires, contaminated oil, organic solvents, etc. for the production of cement clinker increases during the last years. Therefore the number and quantity of heavy metals in clinker increases and their binding and mobility is affected by this. In this research project the incorporation of heavy metals (chromium, vanadium, lead, copper, barium and others) in various clinker minerals, the changes of the properties of cement clinker (crystal structure, texture, etc) and the leachability of heavy metals is studied.

The European Standard prEN 13108-21 "Bitumious mixtures - Quality - Part 21: Factory production control" describes how mixing plants shall operate their production control. In this project six mixing plants of different age and conception were investigated to show the effects of a quality management system as described in prEN 13108-21 on the results of mixture control. It is intended that the results of this project help to estimate future quality costs and their effects on the price of bitumious mixtures. On the other hand the results should assure that the frequencies set in prEN 13108-21 are realistic and that mixing plants are able to fulfill the requirements of this FPC system.

The application of flowable polymer-modified fine aggregate concretes shall be examined for the production of reinforced surface layers (as an alternative to sprayed concrete) in the repair of RC structures. Through examining different polymers and fibres a special concrete shall be developed. It shall achieve the desired qualities like reduced shrinkage, high ductility in elongation and good bond and tensile strength. After optimizing the mixture with rheological measurements and determining the characteristic properties of the fresh and the hardened concrete (including durability and corrosion protection), the application techniques shall be tested on model structures. The final goal shall be the development of a self-compacting polymer-modified fine concrete for the repair and strengthening of RC structures in cases where satisfactory solutions cannot be expected with sprayed concrete.

In Austria the waterproofing of concrete bridgedecks is almost exclusively based on two layers of bitumen sheets. In a research project at the Technical College/Spittal, Project No. 800004 various bridgedeck waterproofing systems were examined for their long-term efficiency. The results showed that the application of polymer bitumen sheets and the use of epoxy resin for sealing the concrete substructure led to a clear improvement of the characteristics of bridgedeck waterproofing systems. Part of this thesis also deals with the effects the European standardizations - which are presently being developed - will have on our national standards. The investigation of bridgedeck waterproofing systems in this thesis consists of the determination of tensile bond and the determination of shear. In doing so, the examination methods of prEN and RVS were applied and then compared with each other.

The knowledge and use of the Poisson's ratio in methods of mixture and pavement design is of primary importance. Test methods to find realistic values, however, are not very common. Mostly they are rather sophisticated and therefor not used in daily laboratory practice. In an Austrian R&D-project a new device has been developed which is able to measure the deformation of test specimens by mean of a video camera, the connected software allows to evaluate the ration simultaneously. In this stdy the Poisson's ration is investigated using Marshall test specimens, both in Marshal tests as well as in indirect tensile tests. Different mixture types will be tested under different test conditions (temperature and deformation rate). In this study a new device has

A new test method to determine caharacteristic fracture mechanic data of concrete, especially mass concrete, is investigated. Large cylindrical specimens (diameter 60 to 110 cm, hight 40 to 60 cm) with an internal penny shaped crack are used. Pressure is slowly applied in the crack using an open or closed (flat jack) hydraulic system and the critical pressure causing instable crack growth is determined to calculate KIc values. Efforts are made to allow the determination of the fracture energy values. The aim of this project is to develop and optimize a new test method for mass concrete, giving engineeers a practical tool to quantitatively evaluate the stability of cracked unreinforced concrete structures. Expected advantages of the method are the relatively simple test set up, the long circular crack-process-zone and the easy production and testing of large specimens.

Furthermore, questions concerning the influence of limestone on the behaviour of concrete admixtures (plasticisers, air entraining agents etc.) and questions concerning the corrosion of reinforcements had been studied.

This research work was done to expand knowledge about outside sprayed-on cellulose insulation application focusing on mechanical and physical properties respectively. Various spraying equipment was used for applying cellulose layers onto brick walls. These spraying experiments indicated that the general performance of the widespread common spraying methods or techniques is rather poor as far as achievable shear stress parameters are concerned. In the testing also glue or bonding agents were used to improve the mechanical properties. Material tests were performed using a tensile testing machine to gain mechanical parameters of spray-applied cellulose insulation layers. The involved parameters were shear stress, tensile resistance (in as well as normal to layer direction) compression strength and thermal conductivity. The results indicated that the tensile resistance of binder reinforced spray-applied cellulose insulation can achieve and even overtop threshold values required for mineral-wool insulation boards (MW-PT). If a more homogeneous mixture between binding and cellulose can be achieved the properties may even be increased distinctly. Concerning the hygro-thermal performance of the system further research work will be done in a following project.

Some Hungarian and Austrian clinker and cement samples have been analysed for their content of strontium, barium, manganese, magnesium, titanium and zirconium, and analytical data processed by statistical ¿pattern recognition" methods: dendrograms were constructed and the significance value of the above elements computed. The recognition is quite good in the case of ordinary Portland cement clinkers, worse in the case of sulphate resistant clinkers. Unfortunately, it turned out that the use of mineral admixtures from other sources causes such a great uncertainty that the identification is not possible.

The experimental work for this diploma thesis was carried out in the laboratories of the Institute for Material Testing and Building Materials Technology and the attached Research and Testing Laboratory (TVFA) of the Technical University Graz. The study started with rheological measurements on cement slurries using three different cements, two additives and three high performance superplasticizers, which gave the starting parameters (combination and dosage of the materials) for the experiments on the concrete itself. For the determination of the characteristics of fresh concrete three test set-ups were used. The Slump-Flow-Test for the determination of the Flow-Slump, the V-Funnel-Test for Funnel time (for the viscosity and cohesion) and a special U-Box-Test for the capability of self-levelling. Twenty-five mixtures were made with varying components and particle-size distribution curves. The results were compared to assess the suitability of each test rig for the determination of the fresh concrete characteristics.

After discussing different standards regulating the requirements for positioning, size and cover of reinforcements in concrete structures (state of the art), the various nondestructive test methods presently used to determine the size, position and cover in reinforced concrete structures are described and particualr emphasis is laid on magnetic measuring methods. Two modern measuring sytemes were selected for detailed performance testing in the laboratory and on site. Both are based on magnetic measuring procedures, i.e. the Profometer 4 from Proceq and the Ferroscan System FS 10 from Hilti. A test program to investigate the effect of different influences such as distance, diameter and type of reinforcement, age and composition of concrete, multilayer reinforcement etc. was carried out and the repeatability and reproduceability of the measurements were determined. Laboratory investigations were followed by practical field applications and the advantages and disavantages of both measuring devices were compared and possibilities for further improvements were suggested.

Objective of this cooperative research project was the development of organic covers as corrosion protection for reinforcing steels capable to withstand chloride solutions as well as aquaous solutions with pH values between 7 and 14. In addition a deposition technology should be devised to apply the protective layers after welding operations in the course of the production process of prefabricated reinforced concrete elements. A total of 35 different protective layers were tested with regard to corrosion resistance in a salt spray test arrangement similar to DIN 50021. Since the results were disappointing, as well with respect to the application techniques as with respect to corrosion resistance, the project was discontinued. not assigned KP: HR Dipl.-Ing.

Electroplating processes and other industrial methods often produce wastes containing heavy metals, such as chromium. If recovery of theses wastes is not feasible, a technical possible remedy can be their immobilisation in cement. At the high pH-value of hardened cement most heavy metals precipitate as hydroxides. Depending on its oxidation state, chromium can either be present as readily soluble chromate (6-valent chromium) or precipitates as chromium-hydroxide (3-valent chromium). Portland cement is usually unsuitable for reducing 6-valent chromium. After being complemented by reducing character additives (such as blast furnace slag, BFS), however, it may be satisfactory. The quantity of safely confinable Cr-load is assessed in this study by pore fluid expression and quasi-dynamic leaching techniques as a function of matrix composition.

Studies were carried out to provide a deeper inside into the mechanismn of electrochemical chloride removal (ECR). They were aimed at determining the changes in (i) total chloride content and (ii) the Cl--and OH--concentrations of the pore solution at varying concrete depths during ECR. It was shown that the efficiency of chloride removal deceased in the concrete cover with increasing depth, and that it was least efficient near the reinforcement. The factor that was identified as being responsible for this was the changes in OH--concentration of the pore solution that had been caused by reactions at the electrodes. The OH--concentration of the pore solution decreased in the area close to the surface during treatment, while it rose dramatically around the reinforcement. This resulted in an increase of the Chloride Transference Number and thus the efficiency of chloride removal close to the concrete surface, and a drastic decrease close to the reinforcement.

Gradually increasing water pressure was applied to internal circular cracks (diameter 10-36 cm) in concrete cylinders (diam. 60 to 110 cm, 40-70 cm high) until unstable crack growth initiated failure. The tests have shown that moderate pressures (50-20 bar) can be sufficient to cause instable growth of relatively small cracks. The influence of sample and test geometry, concrete composition and the feasability to the method for determining KIc values for concrete were investigated.

To meet the specific requirements, waterproofings used for concrete bridge decks must be resistent agianst cracks coming from the concrete below the waterproofing. Otherwise, the penetrating water creates a major corrosion risk to the reinforcing steel. Different bituminous waterproofing membranes and systems have been tested.
