In order to stabilize Black Cotton Soil (BCS), this study focuses on maximizing the combination of ambient-cured geo-polymers such as using sustainable materials including GGBS, fly ash and RHA. Emphasizing environmental sustainability and value-effectiveness, the research explores the effect of these materials at the engineering properties of BCS, particularly specializing in unconfined compressive strength, plasticity index, and limits. Advanced analytical techniques are employed to assess the physical, chemical, and microstructural characteristics of the stabilization method. The efficacy of those geopolymers is evaluated through a sequence of soil tests, including the unconfined compressive strength across numerous curing periods. This study also delves into the usage of alternative materials like agricultural wastes and industrial by-products to enhance soil stabilization techniques, supplying a greener and more cost effective approach to construction and geotechnical engineering.
