Expansive soils are a worldwide problem that poses several challenges for civil engineers. They are considered a potential natural hazard, which can cause extensive damage to structures if not adequately treated. Such soils swell when given an access to water and shrink when they dry out. Utilization of industrial waste materials in the improvement of soils is a cost efficient and environmental friendly method. Stabilisation of the soil is studied by using flyash and ground granulated blast furnace slag. This paper includes the evaluation of soil properties like unconfined compressive strength test and California bearing ratio test. The soil sample was collected from Palur, Tamil Nadu and addition to that, different percentages of flyash (5, 10%, 15% and 20%) and GGBS (15%, 20%, 25%) was added to find the variation in its original strength. Based on these results CBR test was performed with the optimum flyash, optimum GGBS and combination of optimum flyash with varying GGBS percentages (15%, 20%, and 25%). From these results, it was found that optimum GGBS (20%) gives the maximum increment in the CBR value compared with all the other combinations.
