UHPC (ultra high performance concrete) has outstanding strength and durability properties and is therefore particularly suitable for use in infrastructure structures. Due to its physical properties, extremely thin-walled structures can be built. This in turn requires a new way of thinking in construction and design with UHPC compared to reinforced concrete construction.
Since 2000, the LKI has been working on researching the basics of designing and building with UHPC and on developing new construction methods and forms of construction using UHPC. In addition to the numerous research projects on topics such as shear, buckling, prestressed slender columns, containers, railway bridges, fibre orientation measurement....it has also been possible to realise pilot projects such as the construction of the first large arch bridge for road traffic in Völkermarkt. The LKI is currently involved in the development of a set of rules for UHPC in the UHPC working group of the Austrian Association for Structural Engineering.
