Abstract
Black Cotton soil, renowned for its pronounced swelling and shrinkage tendencies, poses significant challenges to construction endeavors. Over time, researchers have endeavored to stabilize this soil type through the incorporation of various additives such as lime, cement, and fly ash. With technological advancements, novel materials are being explored to enhance the efficacy of stabilization processes. This study investigates the potential of Calcium Chloride and Fly Ash as additives to ameliorate the geotechnical characteristics of Black Cotton soil. Calcium Chloride, commonly utilized as a concrete accelerator to promote rapid strength development, and Fly Ash, a by-product of thermal power plants, were employed in differing proportions – Calcium Chloride at 1%, 2%, and 3%, and Fly Ash at 20% and 30%. The specimens underwent curing for durations of 0, 7, 14, and 28 days, and were subjected to alternate wet and dry cycles to assess their swelling and shrinkage behaviors, alongside alterations in the geotechnical properties of Black Cotton Soil.
