Strengthening of Self Compacting Concrete Using Ground Granulated Blast Furnace Slag (GGBS) for Cost Efficiency

To improve the concrete composites and its quality with an economical approach there is a need of some material to reused. Hence, this study focus on achieving towering strength concrete by using these Ground Granulated Blast Furnace Slag which is the waste from iron industry. It is obtained from blast Furnace in water or steam by quenching molten iron Slag. GGBS is used to make durable concrete structure in combination with ordinary Portland cement and other materials. Different test are performed and the percentage of the ground granulated blast furnace slag is varied from 20 %, 30 % and 40 %. The percentage increase in the compressive strength at 30 % addition of GGBS is 1.74 %. Thus, it can be concluded that maximum compressive strength of self compacting concrete with the combination of admixtures (SP+VMA) may be obtained by adding 30 % GGBS which is a waste material of Iron industry.
