Stabilization of Clayey Soil Using Cement, Gypsum and Wheat Husk Ash

This study describes the investigation that carried out to study the effects of Cement, gypsum and wheat husk ash on compaction properties of the clayey soil. Inorganic clay with low Plasticity was used in this study as a natural soil. For this purpose a series of laboratory experiments have been implemented and varieties of samples were made by mixing cement, gypsum and wheat husk ash with natural soil. Three different percentages of gypsum and wheat husk ash (3%, 6% and 9%) used as stabilization materials. The results demonstrated that adding cement has a significant effect on increasing the degree of compaction of the soil samples. In general, the results show that the performance of cement-stabilized soils was superior to gypsum in all the characterizations performed.
