Abstract:In this paper a test was performed on six reinforced concrete rectangular columns subjected to concentric loading up to failure. The material used in this investigation included normal concrete, NC, and reactive powder concrete, RPC. Two columns were cast as control specimens with NC and RPC. The remaining four were of hybrid combination having the NC in the centre and the RPC surrounded it. Variables investigated were the effect of steel fibre volumetric ratio, Vf, (0.5, 1 and 1.5) as well as the thickness of… Show more
