Collapsible soils are black cotton soils with extremely high shear strength when dry but rapidly lose strength when wet. Such rapid and significant loss of strength causes significant distress, resulting in extensive cracking and differential settlements, unstable building foundations, and even the collapse of structures built on these soils. Waste marble dust and Ground Granulated Blast Furnace Slag are industrial byproducts that are produced in massive quantities around the world and pose a threat to the environment. As a result, finding a long-term solution for its disposal is critical. The current study used a physio-chemical technique to reduce the collapse potential of black cotton soil. Because the soil is water-sensitive, it must be stabilised. Different percentages of waste marble dust (WMD) and ground granulated blast furnace slag (GGBFS) were used as an admixture. The effect of admixture on soil parameters such as specific gravity, plasticity index, swelling index, and shrinkage limit is investigated in this study. The study's optimization process revealed that adding waste marble dust improved the geotechnical parameters of black cotton soil significantly. Plasticity was reduced while Unconfined Compressive Strength (UCS) increased significantly. This research evaluates the safe disposal of hazardous waste and converts it into suitable material for engineering purposes
