Stabilization of Red soil by using Boiler Feed Ash

Gobinath Ravindran, G. P. Ganapathy

Abstract


Red soil is the one of the irrigation soil. Most of plants are grown in this soil. The red soil has the most iron content when compared to other soils and it has also got various chemical properties. The red soil has less bearing strength and more water permeability. By the addition of fly ash and BFA to the red soil the liquid limit, plastic limit and bearing strength can be increased. The fly ash is maintained on 10% and the precipitated silica is added from 10% to 50% by replacement of soil. The soil character is changed on the addition of admixtures.
