Concrete is the prime material used for cement concrete road and can exhibits very high compressive strength but lower tensile strength due to internal minor cracks in concrete. Tensile forces are transferred only through the un-cracked concrete. That is the reason why concrete is weak in tension. The present work describes the experimental research on fiber reinforced concrete with M-30 grade in addition of Steel fiber and glass fiber with different percentages, to over-come the internal minor cracks in concrete. The main objective of this thesis work is to investigate the optimum percentage of Steel fiber and glass fiber on M-30 grade concrete and develop a high performance concrete. The research focused on an experimental study to determine and compare compressive
strength, split tensile strength, slump value of concrete grade M-30 having different percentage of iron fiber chip and glass fiber (0%, 0.25%, 0.5%, 0.75%, 1.0%, 1.25%, 1.5%, 1.75%, 2.0%, and 2.25%). Compressive strength, increases up to 1.75% addition of Steel fiber and glass fiber then it were decreased in case of 2.0% and 2.25% were used but split tensile strength increases up to addition of 2.25% Steel fiber and glass fiber. In addition of fiber the workability of concrete was decreased. The chemical admixture is used to increase the workability of concrete.
