The natural coarse aggregate (NCA) in the concrete mix was partially replaced using recycled concrete aggregate (RCA) by 30% with a target compressive strength of 30 MPa after 28 days by adding different types of fiber (steel fiber, recycled steel fiber and mixed fiber) with different percentages (1.0%, 1.5%, and 2.0%) to improve the behavior of different concrete mix. In this study, the mechanical properties and shear behavior of reinforced concrete beams of RCA by adding different types of fiber were investigated. Ten concrete mixtures were designed and ten reinforced concrete beams were tested under a two-point load to estimate the contribution of different types of fiber for shear resistance. The results show the effect of adding different types of fiber (steel fiber, recycled steel fiber and mixed fiber) that were used in concrete mixes was effective in improving and increasing the compressive, tensile, and flexural strength of concrete. Using different types of fiber for recycled concrete aggregate has improved the durability, ductility of concrete, and the ability of concrete to resist cracks due to the increase in shear resistance.
