EFFECT OF STONE DUST ON COMPRESSIVE STRENGTH OF CONCRETE AN EXPERIMENTAL INVESTIGATION

Concrete is the most used construction material having basic ingredients as binding material, fine aggregate, coarse aggregate and water in predetermined proportion all the ingredients are homogeneously mixed to obtain resulting mixed of desired strength. In the present investigation, stone dust, a waste material obtain from crusher plant is used as partial replacement of fine aggregate. M25 grade of concrete was considered for this investigation with a final mix proportion of 1:1.65:3 at w/c ratio of 0.50. The replacement levels of natural fine aggregate with stone dust were 30- 70% at an interval of 10%. The compressive strength of specimens (100mm cubes) cast for different proportions of stone dust was determined and compare the same with referral concrete. The result showed that the stone dust can effectively been used as partial replacement of natural fine aggregate without compromising the compressive strength.
