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. Keywords: Stabilization of soil, Fly ash, GGBS, Black cotton soil, Soil test.

A new non-cement blended materials is developed as a full replacement of cement without alkali activator. This study was conducted to explore a suitable method for activating new ternary green materials with desulfurization gypsum, water-quenched blast-furnace slag and co-fired fly ash from circulating fluidized bed combustion as non-cement inorganic binder. Test subject was included flowability, compressive strength, absorption, total charge-passed from rapid chloride permeability test, chloride diffusion coefficient from accelerated chloride migration test and SEM observation. Test results indicate that a ternary mixture containing 1% desulfurization gypsum, 60% water-quenched blast-furnace slag and 39% co-fired fly ash was a suitable development in compressive strength. The new non-cement blended materials were performed a well compressive strength, lower absorption, and lower chloride diffusion coefficient. In addition, the compressive strength decreased as the inclusion of desulfurization gypsum increased. It was concluded that using desulfurization gypsum alone decreased the setting time and compressive strength. SEM micrographs were verified the development in compressive strength originated from the C-S-H and C-A-S-H gel produced by Ca(OH)2, SiO2, and Al2O3.
