The study of shear behavior of RC beams using recycled concrete aggregate (RCA) has not been a widely investigated area of architectural structure because of variant factors which were difficult to consistently explain. In practice, the shear behavior of RCA beams have been investigated experimentally in order to meet a customer's structural requirements by comparing RC beams made of natural aggregate with those using RCA. In this study, tests have been performed utilizing varied ratios of recycled aggregates and on four concrete mixes (conventional concrete and recycled concrete with 15, 30 and 50% of RCA). Two concrete strengths (normal and high strength) were utilized. Thus, eight reinforced concrete beams were made and tested for shear behavior. The results showed that ultimate loads were little affected by the different types of concretes. Experimental results were compared with current KCI codes and with the shear equation proposed by Zsutty. From these test, it was determined that current KCI codes accurately predicted the shear strength of the recycled concrete, while the Zsutty's equation underestimated the experimental results.
