Rapid industrialization and urbanization has made it mandatory to carry out construction activities on low
bearing soils, which needs to improve the engineering performance of soils. Modification with Portland cement and lime
being costlier increases the overall cost of the project and also cause severe environmental hazards. The aim of this
research work is to study the suitability of Ground Granulated Blast Furnace Slag (GGBS) with lime as a stabilizer of
soil. Use of this blend may develop new opportunities to improve the engineering properties of the soil. For the current
research work, low plastic clayey soil sample was collected from Sanand region of Gujarat, India. The optimum lime
content was determined as 5% by dry weight of soil using Eades and Grim’s pH method. The GGBF Slag replaces lime
in proportion of Lime:GGBF Slag ratio of 5:0, 4:1, 3:2, 2:3, 1:4 and 0:5.Based on unconfined Compressive Strength
results, it has been observed that the Lime can be successfully replaced by GGBF Slag up to 60%.
