: The development of composite concrete beams employing conversional concrete (CC) and lightweight concrete (LWC) is the topic of this research. The typical concrete is made to have an M30 strength. The coarse aggregate of 0%, 20%, 40%, 60%, 80%, and 100% will then be replaced by broken bricks in conventional concrete to create the lightweight concrete for the beam. It was anticipated that the density and strength would decrease as more bricks were added. The amount of air entrainment for the matching density will be examined. Finally, a mix with a reasonable density will be selected to be employed in the composite flexural members together with regular concrete. The main goal is to determine where in a flexural member light weight concrete should be used in addition to conventional concrete. First, during compression, the presumptive position of the light weight and conventional concrete in the cross section of the beam will be studied. The test and cast cubes to determine the cubic strength of various assumed cross sections. Using those findings, the beam will be cast to ensure that the composite material's compression strength is at its highest. It will be tested after curing, and more research on the load to deflection parameter will follow. This enables us to determine whether lightweight concrete may be utilized in beams with traditional concrete.
