Black cotton soil (BCS), known for its high plasticity, low strength, and significant swelling and shrinkage behaviour, poses serious challenges for civil engineering infrastructure. This study investigates the stabilization potential of BCS using an innovative blend of industrial and agricultural by-products—Ground Granulated Blast Furnace Slag (GGBS), nano-silica, and Rice Husk Ash (RHA). The primary objective is to enhance the geotechnical properties of BCS while promoting sustainable and cost-effective construction practices. A series of laboratory experiments were conducted by incorporating varying percentages of GGBS (10%–30%), nano-silica (0.3%–0.9%), and RHA (5%–15%) both individually and in combination. Tests performed include Atterberg limits, standard Proctor compaction, unconfined compressive strength (UCS), California Bearing Ratio (CBR), and free swell index. Results indicate significant improvement in UCS and CBR values with the combined addition of 30% GGBS, 10% RHA, and 0.6% nano-silica, along with a notable reduction in plasticity and swelling potential.
