Flexural Behavior of Hybrid Fiber Reinforced Concrete Deep Beam and Effect of Steel & Polypropylene Fiber on Mechanical Properties of Concrete

Abstract

Concrete is most widely used construction material in the world. Fiber reinforced concrete (FRC) is a concrete in which small and discontinuous fibers are dispersed uniformly. The fibers used in FRC may be of different materials like steel, carbon, glass, polypropylene etc. The addition of these fibers into concrete mass can dramatically increase the compressive strength, tensile strength, flexural strength and impact strength of concrete. The effect of addition of mono fibers and hybrid fibers on the mechanical properties of concrete mixture is studied in the present investigation. In this paper hybrid fibres with crimped steel and polypropylene were used in concrete matrix to study its improvements in strength and durability properties. This paper addresses the compressive strength, split tensile strength, flexure behavior of hybrid fibre reinforced concrete deep beams. The shear span to depth ratio of the beams used in this investigation was maintained as 2. The specimens incorporated steel and polypropylene fibres in the mix proportions of 00-00%, 0-100%, 25-75%, 5050%, 75-25% and 100-00% by volume at a total volume fraction of 1.0%.
