Abstract

Concrete, the most commonly used construction material is prone to cracking for a variety of reasons.These cracks may be recognized as economic,environmental and structural but these cracks are generated because materials are naturally weak in resisting tensile forces.Also, shrinkage causes concrete to crack when restrained Steel fiber reinforcement in the concrete offers a resolution to this problem of cracking by improving tensile strength of concrete.“Fiber Reinforced Concrete” is that concrete in which short-fibers with smaller cross-sectional dimension are added.These are randomly oriented steel fibers in all directions, added reinforcement to the concrete.The mechanical properties of concrete consist of flexural strength, ductility, impact resistance, and, compressive, tensile and abrasion resistance.Improvements in mechanical properties depends upon geometry,the fiber matrix interfacial bond characteristics, volume fraction,the matrix mix proportions,type, material properties of fibers.In this research the effect of varying steel fiber volume fraction on the mechanical properties of concrete are observed in compressive, tensile, flexural and impact resistance of concrete. The test results are analyzed and the optimum fiber volume fraction and aspect ratio of steel fibers is identified.
