Experimental Investigation on Self Compacting Concrete by Partial Replacement of Cement with Fly Ash

Self-compacting concrete (SCC) has high flow ability and cohesive properties as required. It spread and consolidate readily into place (i.e. due to low viscosity) through and around the narrow space/ congested/ dense reinforcement under self-weight. It fills formwork without external vibration or some time little vibration, without segregation and bleeding. This study presents an experimental investigation on self-compacting concrete (SCC) with cement replacement of a FLY ASH (0%, 10%, 20%, 30% and 40%) were cast to study the effect on compressive strength at 14, 28 & chemical admixtures like super plasticizers (SP). After each mix preparation the specimens are cured in water for 3, 7 & 28 days. The slump, J-Box and L-Box test are carried out on the fresh SCC and in harden concrete compressive strength and split tensile strength values are determined. Attempts have been made to study the properties of such SCCs and to investigate the suitability of FLY ASH to be used as partial replacement materials for CEMENT in SCC.
