Özet:

The conventional reinforced concrete is the most used building material in worldwide, concrete characteristics are brittle failure mechanism in tension, it essential to be improved. In concrete mix short descrete steel fibers to be added to recover its brittleness. in this project the optimum percentage of steel fibers are added, then we investigate the flexural behaviour of RC beam. In this project the hooked end steel fibers of 0.75mm Dia and 50mm length are added in reinforced concrete beam with concrete compressive strength of 30MPa (M30). The optimum percentage of steel fibers added to concrete mix, 15 cubes, 15 cylinders, 15 beams with 5 different percentages (i.e 0%, 0.75%, 1%, 1.25%, 1.5%) have been tested. The dimension of beam is 700mm x 150mm x 150mm. in this study flexural behaviour of steel fiber added reinforced concrete beams compared to normal (or) conventional reinforced beam with no steel fibers, the steel fiber reinforced beams were tested under flexure using a third-point loading test setup for M30 concrete.
