Abstract:
The use of ultra-high-strength concrete for the construction of some types of structural members can be considered if nonbrittle behavior is achieved. Paper introduces reactive powder concretes (RPC) that exhibit ultra-high strength and high ductility at the same time. Compared to conventional concretes, the ductility estimated in terms of fracture energy is increased by one to two orders of magnitude, while the compressive strength values are in the range of 200 to 800 MPa..
