Stabilization of Soft Clay Soil by using Cement and Fly Ash

Abstract

Soil stabilization has become the main issue in construction. Engineering and researches concerning the effectiveness of exploitation industrial wastes as a stabilizer are gradually increasing. This paper shortly describes the quality of the local ash to be used in the local construction industry in a way to minimize the quantity of waste to be disposed to the environment causing environmental pollution. Many civil engineering laboratory tests are conducted to study the geotechnical properties of fly ash and strength gain mixed with clay samples. a different proportion of fly ash and soil sample cured for fourteen days’ results in a strength gain. Understanding of the properties of fly ash is gained from the study and the tests indicates an improved strength and better properties of soft soil sample when stabilized.
