In general, all the mines affect their surrounding environment to a little or more extent, but open cast mining i.e. in case of marble, granite, lime stone, sandstone and other type of building stone quarries leads to complex nature of environmental problems such as Choking of drains in rainy season , Dust nuisance , Fine particles of slurry (with size less than 363 micron) become air borne and cause air pollution , Slurry affects productivity of land due to decreased porosity, water absorption

Thus, seriously affecting underground water availability so these waste materials needs to be utilized meaningfully in an economic way. Waste can be used to produce new products or can be used as admixtures so that natural resources are used more efficiently and the environment is protected from waste deposits. 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 that paper Broken marble is replace by Coarse aggregates the project is carried out by using M20 grade concrete with replacementof0%,5%,10%,15%,20%,25%,30%,35%,40%,45 %,50% broken marble pieces by coarse aggregates and is carried out to determine the optimum percentage of replacement at which maximum compressive strength is achieved .There are several reuse and recycling solutions for this industrial by-product, both at an experimental phase and in practical applications. These industrial wastes are dumped in the nearby land and the natural fertility of the soil is spoiled.
