Durability of Ultra High Strength Fibre Reinforced Concrete (UHSFRC) B 150 - B 200

Subject Area Construction Material Sciences, Chemistry, Building Physics
Term from 2003 to 2011
Project identifier Deutsche Forschungsgemeinschaft (DFG) - Project number 5400152
 
High strength concretes have been developed within recent years and strength classes up to B 115 belong to the status of contemporary concrete technology. For concretes of even higher strength classes ranging between 150 - 200 N/mm2 fabrication techniques and production engineering are either available or already far-advanced but little is known about functional properties of such construction materials. Particularly the lack of knowledge associated with fatigue and durability behaviour is one of the obstacles to a wider application of these ultra high strength concretes. The present request for a joint research project aims at compensating the existing knowledge deficiency towards a broader application of ultra high strength concretes. Within the intended working plan, the fatigue behaviour of these concretes will be investigated by TU Delft in The Netherlands, and University Karlsruhe will carry out experiments on durability. The samples of the same concrete mixes will be used and in addition an exchange of tested concrete specimens between the project partners will be realized. In particular samples already tested for durability in Karlsruhe are going to be examinated in Delft with regard to their fatigue behaviour and vice versa.
