Abstract:
Concrete is a composite material composed of coarse aggregate bonded together with fluid cement that hardens over time. Concrete has relatively high compressive strength, than the tensile strength. For this reason it is usually reinforced with materials that are strong in tension. The tensile strength of the concrete can be increased by the addition of the glass fibers, steel fibers, nylon fibers etc. Fibre reinforced concrete (FRC) is cementing concrete reinforced mixture with more or less randomly distributed small fibres. In the FRC, a numbers of small fibres are dispersed and distributed randomly in the concrete at the time of mixing, and thus improve concrete properties in all directions. In this project we are aimed to study the effect of shape of steel fibers on mechanical properties of fiber reinforced concrete. For this purpose M30 grade concrete is chosen as the mix. Different shapes of fibers like hooked end, crimped are used in this study as an addition in percentage likes 1%, 2%, 3%, and 4% to the weight of cement. From the test results we came to conclusion that the Mix with crimped shaped fibre shows more resistance to both compressive and split tensile strength than the Mixes with hooked shaped fibre and conventional at an percentage of 2% with the weight of cement. In comparison use of crimped shapes fibre in concrete gives more satisfactory results than the hooked shaped fibre.
