Experimental Investigation on Mechanical Properties of Steel Fibre in M50 Grade Concrete

In the construction industry, concrete was the important one, and nowadays many researchers are involved to make concrete with different performances. In this research work, steel fibre was introduced in the manufacturing of concrete. The steel fibre was added in various proportions in M50 grade concrete from 0, 0.5, 1, 1.5, and 2%. The steel-fibre-reinforced concrete was compared with the conventional concrete and found the optimum percentage. In this research work, the mechanical properties, microstructure analysis and failure analysis of the RCC beam were discussed. The maximum amount of steel fibre in concrete was 1%. The addition of steel fibre enhances the strength in concrete and reduces crack failure in concrete. Microstructure analysis like SEM, EDX, and XRD was examined and studied about the surface structure of the fibre-reinforced concrete.
