Expansive Clays, also termed as swelling soils or shrink-swell soils, have a tendency to swell and shrink with the variation in moisture content. As a result of which significant distress in the soil occurs, causing severe damage to the overlying structure. During monsoons, these soils imbibe water, swell, become soft and their capacity to bear water is reduced, while in drier seasons, these soils shrink and become harder due to evaporation of water. These types of soils are generally found in arid and semi-arid regions of the world and are considered as a potential natural hazard, which if not treated well can cause extensive damages to the structures built upon them. Soils containing the clay mineral, montmorillonite generally exhibit these properties. In India, these soils are also called as Black cotton soils. Stabilization using solid wastes is one of the different techniques to improve the engineering properties of expansive clays to make them suitable for construction. Hence, in this project, the influence of two industrial wastes, Ground Granulated Blast Furnace Slag (GGBS) and Palm Oil Fuel Ash (POFA) in different percentages, as stabilizing materials for enhancing the properties of expansive clay is evaluated by conducting various tests. The results will be analyzed to assess the efficiency of the materials used.
