Feasibility of Cement Concrete by Partially Replacing Cement by Marble dust in Cement Concrete

Abstract

It has now become popular to use marble dust in concrete as a partial replacement of cement or partial replacement of sand for improving the properties of concrete and also to reduce the effect of gas evolved from concrete surface in the environment. Huge waste is generated from marble industries in the form of marble powder which has reached millions of tonnes and it has now become severe problem for disposing this marble dust, so idea of this paper is to use this marble dust in concrete as a partial replacement of cement. Use of marble dust in cement concrete not only help in reducing the disposing problem but also help in reducing the effect of gases evolved from concrete surface in the environment and also reduce the cost of concrete . Marble dust is partially replaced in cement in percentage of 0, 5,10,15,20 in this paper and slump cone test, compressive strength test of cement concrete cubes are performed. For Compressive strength of cube mould of 150mm×150 mm is used and compressive strength is checked on 7 days and 28 days. All tests are performed on M15 concrete.
