Study on Properties of SCC with Partial Replacement of Cement by GGBFS and Fly Ash
Keywords:self-compacting concrete, fly ash, Ground Granulated Blast Furnace Slag, Workability, Strength
This paper presents experimental study on the properties of self-compacting concrete (SCC) amended with two additional cementitious materials (fly ash and slag) on the mechanical performance of self-compacting concrete (SCC). Portland cement (PC) was replaced with fly ash (FA), Ground Granulated Blast Furnace Slag (GGBFS). The effect of these admixtures on the fresh and hardened SCC of various mix proportions was studied. It was observed there was only very small difference in workability and strength of SCC when the cement was partially (30%) replaced by GGBFS and Fly ash at various proportions. From the results obtained GGBFS replacement in concrete, considerably increase the strength of concrete.
