An Efficient and Stabilization of Lithomargic Soil Using alkali activated Fly ash

Abstract

Due to cohesiveness property in expansive soil, it becameweak and good for foundation or pavement subgrade. Soil Stabilization is one of the most important aspects ofthe construction industry, which is used widely in foundation and road pavement constructions; this is because suchstabilization improves Geotechnical properties of the soil, such as volume stability, strength and durability.Alkali activated flyashes are the cement for the future. The alkali activation of wastematerials is a chemical process that allows the user to transform glassy structures (partially ortotally amorphous and/or metastable) into very compact well-cemented composites.The present study focuses on investigations on the engineering properties of Lithomargicsoils. Attempts are being made to investigate the study on Stabilization of Lithomargic soil (silty-soil) by using alkali activated polymers combined with Fly-ash.
