Nowadays, research about concrete technology has led to a concrete with high performance (ultra-high concrete). Various innovations are also used to support the ultra-high concrete. In concrete engineering, we always avoid shear failure due to its brittleness. In this study, innovative additives will be used in the form of fiber steel fiber with the aim to increase the shear strength of the concrete powder. Tests in the laboratory will be carried out on samples of fiber-reinforced concrete beam specimens and to study the effect of increasing shear strength due to the addition of fiber (steel fiber), the variable is aspect ratio (fiber length versus fiber diameter) varied 75, 100, 125,165,180 and volume aspects ( 0.1%, 0.2%, 0.3, 0.4, 0.5%, 0.6%). And the greater the percentage of steel fiber volume can increase the shear strength, the greater the fiber-reinforced concrete, but the workability will be lower. In order for workability to remain good, the recommended fiber volume is 0.3% and the aspect ratio using the critical length of the fiber compared to the diameter of the fiber.
