Addition of Steel Fiber’s in Concrete – A Review

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