Abstract: Expansive clay soils are geotechnically problematic in nature as they possess less shear strength, high compressibility and low permeability. This research work was carried out with a view to improve index and engineering properties of expansive soil by stabilizing it with industrial wastes and geopolymers. The industrial wastes such as fly ash, silica fume and sodium-hydroxide were used for the stabilization of expansive soil. the virgin clay soil was tested for its index properties, compaction characteristics and shear strength determination. the stabilization of clay is made by adding and mixing those materials by varying its percentage. In the stabilization of soil with sodium hydroxide, an attempt has been made to study the effect of its molarity on the various properties of the soil. The clay soil stabilized with various materials was also tested for the same properties and that results were compared with that of virgin soil to find the effect of stabilization.
Keywords: Clay, Stabilization, Flyash, Silicafume, Sodium hydroxide.
