Addition of Steel Fiber’s in Concrete – A Review

Abstract

– Composite material composed of fine and coarse aggregate bonded together with water cement that hardens over time is called a concrete. Steel fibres will enhance to crack resistance of the concrete, and they can also be used to replace or supplement structural reinforcement. SF’s are added in concrete as they are light weight, economical and enhance strength of concrete or reinforced concrete. The review study years mentioned in this paper were from 1991-2023 of how and what amount of steel fibres are needed to be entertained in concrete. Steel fibres are added in concrete alone or sometimes with another material such as marble powder or rice husk etc. in all of the studies it is concluded that using steel fibres up to 30kg with replacement enhances properties of concrete, good flexural behaviour also increase its toughness.
