Experimental study on strength property of concrete by partial replacement of fine aggregate with dolomite powder

Abstract

Concrete is a building material made from a mixture of broken stone, sand, cement and water which can be spread into moulds. M60 grade of concrete is used in the mix ratio of 1:1.2:1.58. Dolomite powder is replaced for fine aggregate in the ratio of 10%, 20%, 30%, 40%. The compressive, split tensile and flexural strengths of concrete with dolomite powder were compared with those of the conventional concrete. The results indicate that replacement of fine aggregate with dolomite powder at 30% increases the compressive split tensile & flexural strength of concrete.
