As a universal truth, concrete is weak in tension, it has less ductile property and little resistance to cracking. Hence Fiber Reinforced Concrete is being used popularly against PCC (Plain cement concrete) which gives more ductility, resistance to cracking and strengthening of concrete. Due to the richer flexural strength property of fiber reinforced concrete, it can act as crack arrester.An attempt is made in this dissertation work to investigate experimentally the performance of fiber reinforced concrete with regard to compressive strength and flexural strength by varying the percentage of steel fibers. The percentage variation of steel fiber from 0%, 1%, 2%, 3% and 4% by weight of concrete is added in the designed mix concrete of M-25 grade. The type of Steel fiber used is of hooked end of aspect ratio 66.67. The cubes and prism were cured for 7, 14 and 28 days and tested to understand the compressive strength and flexural strength. Model RCC (Reinforced cement concrete ) beams of 700X150X150mm with nominal longitudinal reinforcement and shear reinforcement with a layer of steel fiber provided at 5cm from bottom of beam unidirectional with varying percentages of steel fibers (0% to 4%) were cast and cured for 28 days. The beams were tested under two point loading system and load deflection characteristics are recorded. It is observed that the beams having a layer at 5cm level have shown excellent ductility characteristics giving sufficient warning before complete failure.
