Comparative Study on Properties of Soil replaced with Agrowaste Stabilized using Metakaolin and Cement as Additives

Abstract—Soil stabilization is a technique of refining properties of soil by combining with other materials. It is the course of enhancing the shear strength parameters of soil and thereby increasing the bearing capacity of soil. Soil stabilization is used to lessen permeability and compressibility of the soil mass in earth structures. In common soil stabilization changes physical, chemical and mechanical properties to meet the engineering principle. Soil stabilization can be achieved by in-situ stabilization or ex-situ stabilization methodology. In the present case, an investigation is done to increase the strength properties of cohesive soil using a rice husk ash which is an agro waste and the mixture is treated with metakaolin and cement as an additive and is tested for various strength parameters.
