Effect of silica Fume on Compressive and Tensile Strength of Concrete

Abstract

Effect of Silica Fume on compressive and tensile strength of concrete is proving to be a novel development. Concrete being a composite material packed with particle ranging from millimeters to nanometer, the addition of Silica Fume can improve its various performance features. A concrete with target characteristic compressive strength of 40 Mpa was designed for a ‘very serve’ exposure condition satisfying the durability requirements of IRC-112 and workability requirements of MoRTH. To know the effect of replacement of a different percentage of cement with Silica Fume on compressive and tensile strength of concrete. To find out the optimum quantity of cement to be replaced by Silica Fume in concrete for the safe and economic design.
