Stone, one of the most common building material of ancient times, is an ubiquitous material. A sustainable growth in the consumption of stone is observed all over the world in the recent years. Various types of stone such as-granite, Kota stone, marble, limestone, slate etc. are used in construction purposes. In the building industry, Marble/Kota stone has been commonly used for various purposes like flooring, cladding, balconies, wall fixing etc., as a building material since the ancient times. Marble/Kota stone industry generates both solid waste and stone slurry. Whereas solid waste results from the rejects at the mine sites or at the processing units, stone slurry is a semi liquid substance consisting of particles originating from the sawing and the polishing processes and water used to cool and lubricate the sawing and polishing machines. During the process of cutting, in that original stone waste mass is lost by 25% in the form of dust. Accordingly, the amount of mining and processing waste has increased. Stone waste is generally a highly polluting waste due to both its highly alkaline nature, and its manufacturing and processing techniques, which impose a health threat to the surroundings. The generated sludge from stone cutting factories is prohibited from being discharged to the public sanitary system. Use of stone waste in various engineering applications can solve the problem of disposing of stone waste and other purposes. Stone waste can be used in concrete to improve its strength and other durability factors. Stone waste can be used as a partial replacement of cement or replacement of fine aggregate and as a supplementary addition to achieve different properties of concrete. The use of the replacement materials offer cost reduction, energy savings, arguably superior products, and fewer hazards in the environment.
