This study investigates the effect of using recycled concrete aggregates (RCA) on the flexural behavior and ultimate capacity of reinforced concrete beams experimentally. A total of four reinforced concrete (RC) beam specimens were flexural tested until failure. The parameter investigated included the RCA replacement ratio (0%, 25%, 50%, and 100%). The testing results of the specimens were compared to control beam specimens made with natural coarse aggregates (NCA). In addition, the experimental results of beams with RCA were compared to the result of the beam without RCA. Test Results showed there was no remarkable effect of using RCA on the flexural strength of the tested beams. Keywords— Recycled Concrete Aggregates, Flexural Behavior, Concrete Beams, Sustainable Materials.
