The amount of solid waste being produced all over the globe is causing drastic effects on the environment. The solid waste disposal has been causing pollution and damages related to it. The marble mining and production industry creates masses of solid waste, with no methodical process for its disposal. Marble slurry is marble fines suspended in water, generated during the processing of marble. It constitutes 10% of the total stone quarried and 5-7% produced during polishing. Various studies have been conducted on the proper disposal of the solid waste generated during marble processing. This study if focused on the use of marble slurry as partial or complete replacement of aggregate in cement mortar. It elaborates on the tests conducted for compressive strength, abrasion resistance and water absorption in mortar specimen.
