Properties Change in Cohesive Soil using Lime and Fly Ash

Abstract

Soil Stabilization may be broadly defined as alteration or preservation of one or more soil properties to improve the engineering characteristics and performance of a soil. Particularly, with proper treatment, expansive soil carries the load of a structure on the soil strata. So, durability and soundness of the structure mainly depend on the soil types and characteristics. Previous research works showed that there was a potential of using silica waste and other materials for stabilizing the expansive soil to carry the various structures. Further, numbers of researches have studied the physical and chemical properties of fly ash and rice husk ash which was also used as a stabilizing agent for expansive soil. For stabilizing the soil, FA alone cannot be used as a stabilizing agent due to the lack of cementations properties such as lime. This paper presented the result of the effect of change in the index properties of soil using fly ash with lime, not only for strength development but also the durability of lime stabilizing soil.
