Abstract: Soil stabilization has become the more issue in construction activity. In this study we focus on improvement of soil by using Fly ash and ground granulated blast furnace slag (GGBS). In many villages there was demolition of houses due to flood situation and landslide so stabilization of soil is very important factor in this area. In these studies we use local Fly ash and Ground granulated blast furnace slag (GGBS) for stabilization of soil. Soil are generally stabilized to increase their strength and durability or to prevent soil erosion. The properties of soil vary a great deal at different places or in certain cases even at one place the success of soil stabilization depends on soil testing. Various methods are there to stabilize soil and the method should be verified in the lab with the soil material before applying it on the field. The various percentages of Fly ash and GGBS were mixed with soil sample to conduct soil test. Using fly ash reduces the plasticity index which has potential impact on engineering properties also GGBS has cementations property which acts as binding material for the soil. On addition of 15% Fly ash and 5% GGBS increase the strength of soil (according to IS2720:1985) it’s recommended for better result.
