Abstract

Abstract Reactive powder concrete (RPC) is a special type of concrete, it is rather a mortar than an actual concrete mixture, because traditional coarse and fine aggregate are replaced by very fine sand with particle size in range of (150-400)µm. In the present experimental investigation, compressive strength, splitting tensile strength and flexural strength of plain reactive powder concrete and reactive powder concrete reinforced with 1% and 2% steel fiber are compared, by using local available material and curing in 20°C and 80°C, and the experimental study was curried out on a two sets of samples. Each set consisted of (54) cubes of (50×50×50mm), (18) cylinder of (100×200mm) and (18) prism of (50×50×300mm). The results show that the maximum compressive strength is 74 MPa with 2% steel fiber and curing in 20°C. The addition of steel fiber by 1% and 2%increased the compressive strength, splitting tensile strength and flexural strength.
