Lab scale Footing Analysis on Stabilization of Black Cotton Soil

Abstract

Expansive soil implies low bearing capacity and high swelling property perhaps causes serious problems during construction includes low stability, non-uniform settlements and shear distribution. The soil stabilization is one such method to improve the process and it depends upon the soil condition and the nature of soil according to the desired requirements of footing. This study aims to increase the index and engineering properties of soil by addition of the natural fiber (sisal), lime and silica fume. Soil stabilization by lime involves the admixture in the form of calcium oxide or calcium hydroxide to the soil and silica fume as an industrial waste by product acts as a pore filling material. The project is economically viable because the stabilizing materials are easily available and less cost. This project is also analyzed by using the PLAXIS software.
