Static response and modelling of impact resistance of UHPFRCC slab specimens

The demand for improved properties of the construction materials increase with time and the related design and construction codes are adapted in an analogous manner. UHPFRCCs represent a class of cement composites which have superior characteristics in terms of material properties. Their mechanical and fracture behaviour is substantially enhanced compared to other types of concrete. These materials have, however, a significant increase in cost over and above that of conventional and even High Performance Concrete and it is therefore appropriate to identify applications which will fully utilize their mechanical properties and performance characteristics. The aim of this study is to present the results on the development of an UHPFRCC, the experimental investigation of the quality and the behaviour of this material in a highly demanding application, such as the impact resistance of structures and finally the development of a Finite Element Analysis program which will form a basis for analysis of future field tests.
