ABSTRACT

Clay soil was stabilized using cassava peel ash (CPA), rice husk ash (RHA), gypsum, and littorina littorea (periwinkle) shell ash (PSA). The soil is classified as a medium coarse sandy clay. Periwinkle shell ash (PSA), followed by gypsum was shown to be the best stabilizing element in the tests. The compressive strength of the soil was increased by the periwinkle shell, and it was diminished by CPA. Because of their improved compressive strength and flexural strength, periwinkle shell ash, gypsum, and RHA are ideal materials for clay soil stabilization. The stabilized clay’s specific gravity and moisture content are both acceptable. These compounds are recommended for stabilizing sandy clay soils since they improve the engineering qualities of such soils in general.
