As urbanization advances rapidly, the need arises to build infrastructure on challenging soils, demanding their reinforcement and enhancement. To assess the efficacy of using unconventional materials in geotechnical practices, there's an endeavor to use alccofine in soil stabilization methods instead of traditional additives such as fly ash, lime, and cement. This study explores the utilization of alccofine, a by-product material derived from glass industry, to improve the geotechnical characteristics of soil. Alccofine is employed as a sustainable, non-toxic, and environmentally friendly stabilizer as observed from XRF and XRD analysis. This study aims to stabilize black cotton soil (BCS) by using alccofine at concentrations of 2%, 4%, 7%, and 10%(w/w). Under curing times ranging 7, 14, and 21 days, the strength and swell properties of treated and untreated soil are compared. The results make it abundantly evident that increasing the curing period greatly improved the soil's strength and decreased its swelling properties after treating it with alccofine. This paper mainly focuses on how BCS that has been amended with alccofine responds in terms of strength and swelling characteristics, as well as how to improve the alccofine-soil composites interaction mechanism. Therefore, it can be asserted that alccofine exhibits considerable promise as a soil stabilizer, offering enhanced strength and sustainability to structures.
