Performance of Self Compacted Concrete With Steel Slag Replacing Coarse Aggregate

Self-compacting concrete, also referred to as self-consolidating concrete, is able to flow and consolidate under its own weight. This makes SCC particularly useful wherever placing is difficult, such as in heavily-reinforced concrete members or in complicated work forms. The objective of this research was to check the mechanical properties of self-compacted high strength concrete using steel slag as partial replacement of coarse aggregate. Cube specimen (15x15x15)cm were tested for compressive strength, cylinder specimen (15x30)Cm were tested for tensile strength and beam specimen (50x10x10)cm were tested for flexural strength after 7 days,28 days and 56 days of curing, in order to find out if self-compacting concrete would show an increase in these strength. The mix design used for making self-compacted concrete specimen was based on the previous research work on this topic and from literature. The water – cement ratio varied from 0.40 while the cement, fine aggregate and admixture were kept same, expect the coarse aggregate and steel slag were change for obtaining the best result.
