My research work is oriented towards the extended studies on stabilization of soil using industrial waste Granulated Ground Blast Furnace Slag (GGBFS) to achieve positive results for index properties, compaction characteristics and strength characteristics by investigating so many soil samples with varying proportions of GGBFS and Fly Ash by weight of soil. Main objective of this research paper is to elaborate and take previous studies to another level and to establish a conclusion that GGBFS and FlyAsh are best byproduct stabilizer material for increasing the strength and stability of soil by investigating samples of soil. In this dissertation, effect of GGBFS and Fly Ash on various engineering properties, i.e. plastic limit, liquid limit, specific gravity, optimum moisture content, maximum dry density, unconfined compressive strength and California bearing ratio value have been investigated. During the course of investigation, GGBFS and FlyAsh were used in proportions of 0%, 5%, 10%, 15%, 20%, 25%, 30% and 0%, 3%, 6%, 9%, 12%, 15%, 18% respectively by weight of soil sample for various experiments. Finally, on the bases of experimental results it is concluded that the utilization of industrial wastes, i.e. GGBFS and Fly Ash are much effective in terms of cost, time, stability, strength and also environment friendly for the construction purpose.
