ABSTRACT- Although it is commonly known that concrete has a high compressive strength, when it is subjected to impact and dynamic stresses, its brittle mode of failure is seen as a disadvantage. This may be avoided by increasing the flexural strength of a brittle matrix by adding fibres, which is a well-known technique. Additionally, the interaction between the fibres and the matrix determines how well the reinforcements work. This study's goal is to figure out how strong fibre reinforced concrete (FRC), which contains variable concentrations of steel fibres, is mechanically. According to the testing technique specified by the Indian Standard, samples of plain and fiber-reinforced concrete that had been curing for 28 days each were used for the compressive strength, split tensile strength, and flexural strength tests. Concrete was mixed with crimped steel fibre in a range of concentrations, including 0%, 1.0%, 1.5%, 2%, 2.5% and 3% with a water-to-cement ratio of 0.42 and an aspect ratio of 50. According to the test results, the (FRC) was efficient under impact loads, increasing impact resistance.
