Influence of GGBS and Mono Steel Fiber on Strength Characteristics of Self-Compacting Concrete

Abstract

In recent scenarios, self-compacting concrete (SCC) has played a vital role in the construction industry. In the fresh state, SCC has flow ability, passing ability, and filling ability. SCC also had better strength and durability properties. The addition of fiber content in SCC could improve the tensile properties. The present research aims to investigate the strength aspects of SCC using a combination of steel fibers with mineral admixture namely Ground Granulated Blast Furnace Slag (GGBS) in constant 30%. The fresh properties of SCC were highly influenced by GGBS since it is used as a powder content/ fines. However, the addition of steel fibers (STF) from 0% to 2% with an increment of 0.5% has decreased the flowability property in SCC. From the obtained results, the addition of 2% STF along with 30% GGBS has improved the strength when compared to the control mix of the same grade and also resisted the crack propagations.
