Experimental and Analytical Investigation on Steel Fiber Reinforced Concrete

Abstract

: In this research, the mechanical properties of steel fiber reinforced concrete were investigated experimentally and the results compared with analytical models. Hooked end steel fibers of aspect ratio 50 were added at three proportions and compared with plain concrete. The fiber content is varied at 0%, 0.5%, 0.75%, 1% volume of concrete. The water cement ratio used was 0.51. Tests for compressive strength, flexure strength, splitting tensile strength, modulus of elasticity, impact test on cubes and impact test on slabs were conducted to investigate the influence of hooked end steel fibers in concrete. The experimental results for flexure test and impact test on slabs were compared with analytical results. Analytical study was conducted using commercially available finite element software, ABAQUS.
