Expansive soil, Nano particles, Soil Stabilization


The behavior of structures depends on the properties of the soil on which they are constructed. Some problems like settlement and bearing capacity are critical for structures over the expansive soil, the soil sample has been characterized as expansive soil based on swelling test. Stabilization techniques are adopted to enhance the expansive soil behavior and performance of foundation overlying weak soil. This paper focuses on studying the effect of nanomaterials (Nano MgO and Nano Al2O3) with different proportions viz. 0.5%, 1.0%, 1.5% and 2.0% on the properties of expansive soil. The results indicate that swelling potential is reduced with the addition of these nanomaterials and thus making the soil suitable for construction purposes.
