Experimental Investigation on Concrete by Partial Replacement of Marble Powder and Bore Well Sand

Concrete is the most widely used construction material in civil engineering industry because of its high structural strength and stability. Leaving the waste materials to the environment directly can cause environmental problem.  Marble stone industry generates both solid waste and stone slurry. The concrete industry is constantly looking for supplementary material with the objective of reducing the solid waste disposal problem.  In this paper cement is replace by marble powder the research is carried out by using M25 grade concrete with replacement of 5%, 10%, 15% marble powder by cement in addition of 50% replacement of normal sand by bore well sand and is carried out to determine the optimum percentage of replacement at which maximum compressive Strength, split tensile strength, flexural strength is achieved.
