Abstract

In recent years, due to the progress in the field of concrete technology, some types of high-performance concrete and ultra-high-performance concrete have been developed. Reactive powder concrete (RPC), as a new type of ultra-high-performance concrete, was first patented by a French construction company in 1994. The superior properties of RPC such as high compressive strength (more than 150 MPa), high packing density, very low permeability and higher durability are achieved by eliminating the coarse aggregates and substituting them with fine silica sand aggregates, using high amount of silica fume and low water to cement ratio. Steel fibers are another materials used in RPC. The results of researches show that fibers have the main effect on the increasing of flexural strength, ductility and energy absorption, as in some cases, RPC’s flexural strength has been reached up to 40 MPa [1].
