Abstract: Aggregate interlocking has the ability to transfer the load from one side to other by a narrow irregular crack. Aggregate interlocking and dowel action are the key parameters to transfer the shear strength in reinforced concrete members. In this study, experimental work has been carried out on reinforced concrete beams with and without aggregate interlocking connection through implementing initial crack and simultaneously varying the percentage of longitudinal reinforcement under flexure using four-point loading. The flexural strength of the reinforced concrete beams has been assessed through load-deflection curve, ductility and flexural strength resulted from four-point bending test. From experimental study, it has been observed that by varying the percentage of longitudinal reinforcement, the flexural strength of the beam significantly increased.
