Abstract

Concrete in construction, is a structural material consisting of a hard, chemically inert particulate substance, known as aggregate (usually sand and gravel) that is bonded together by cement and water. Concrete is good in compression but weak in tension, hence new advancements are implemented like using steel fibres (SF) in concrete which will strengthen the tensile zone. An increased compressive, splitting tensile and flexural strength, flexural toughness, surface hardness, and abrasion resistance, and a decreased water absorption and sorptivity of concrete with an increased steel fibre content from 1% to 2% can be observed (Kaplan et al.2021).The main aim of this study is to achieve an acceptable ordinary-strength. Steel fiber (SF) is the most popular type of fiber used as concrete reinforcement. Addition of SFs in concrete significantly increases its flexural toughness, the energy absorption capacity, ductile behavior prior to the ultimate failure, reduced cracking, and improved durability.
