ABSTRACT
The aim of present study is to investigate the mechanical strength of RPC containing various percentages of silica fume partially replaced with cement. The Reactive Powder Concrete is made with different proportions of silica fume varying from 0% up to 50% as a partial replacement of cement. The investigation shows partial replacement of silica fume by 25% with cement gives improved mechanical strength properties of concrete. The quality of the RPC is assessed by using rebound hammer and ultrasonic pulse velocity. The relation between compressive and flexural strength is also proposed in the form of statistical equation for the RPC.
