Abstract: Plain concrete has a very low tensile strength, limited flexibility, and very little resistance to cracking. It also has extremely restricted ductility. There is an inherent presence of internal micro cracks in the concrete, and the weak tensile strength of the concrete is actually caused by the development of these micro cracks, which ultimately results in the concrete breaking into brittle pieces. It has been established that the incorporation of small fibers that are consistently scattered and tightly spaced into concrete would not only serve as a crack arrester but would also significantly enhance the concrete's compressive and flexural strength qualities. Fiber reinforced concrete is the name given to this particular form of concrete. In this particular study, the steel fibers were utilized. 50 millimeters on each side is the ratio of the length to the aspect ratio of the steel fibers. As part of the ongoing inquiry, an effort has been undertaken to improve the strength of concrete by including steel fibers into the mixture. In order to investigate the variance in compressive strength, a cube with dimensions of 150 millimeters by 150 millimeters by 150 millimeters was cast. Steel fibers were cast into three different numbers of cubes, each of which had a different percentage. By weight of cement, the steel fiber was added at a percentage of 0%, 0.5%, 1%, and 1.5% respectively. For the purpose of analyzing the variance in the splintered tensile strength of concrete, a cylindrical specimen with a bottom diameter of 150 millimeters and a height of 300 millimeters was purchased. Different percentages of steel fibers were used to determine the cost of three different numbers of cylindrical specimens. There were four different percentages of steel fibers added to the cement: 0%, 0.5%, 1%, and 1.5% by weight. The compressive strength and split tensile strength of concrete can be increased by increasing the quantity of steel fibers incorporated into the concrete up to a certain limit. The experimental study illustrates the many levels of strength that can be achieved by incorporating steel fibers into concrete. Concrete of the M20 grade is used for the research, and the compressive strength and split tensile strength of concrete at the ages of seven days and twenty-eight days are estimated based on the results of the tests that were carried out. Furthermore, it has been discovered that the inclusion of one percent steel fiber by weight of cement results in the highest possible compressive strength and split tensile strength.
