Experimental Study by Use of GGBS as Partial Replacement of Cement on Compressive Strength of Concrete

Abstract

Abstract: Compressive strength may be increased by using mineral admixtures by replacing some amount of the cement in concrete. Several widely used mineral admixtures include silica fume (SF), ground granulated blast furnace slag (GGBS), and fly ash (FA). In this paper, GGBS admixture is employed to replace cement at percentages of 10%, 20%, 30%, and 35%. Concrete comes in two varieties, M-30 and M-35, which are both utilized. The Different percentage of GGBS are tested in order to see how they affect the concrete's strength. According to the findings, GGBS does have a role in raising concrete's compressive strength. At 20% cement substitution, GGBS improves the compressive strength of both concrete mixes. Then, they lowered the concrete's compressive strength.
