In this investigation, studies were done to know the effect of the presence of recycled coarse aggregates (RCA) and Pozzolans in shear deficient rectangular beams in evaluating the shear strength of concrete. The selected slender and moderate deep beams without shear reinforcement were tested under two-point loading and the obtained results are compared with the renowned research work and design codes on natural coarse aggregates. An important observation is the replacement ratio of RCA is an

The proposed method is then verified using the available experimental data of 330 RCA and NCA data of rectangular beams without stirrups.
