In this research, an analysis is conducted on the bending strength of composite concrete beams made up of high-strength concrete (HSC) and normal strength concrete (NSC) in various combinations. The main purpose of this study is to examine the effect of different combinations on the performance of reinforced concrete beams. There were three different kinds of composite layers that were studied. In the first arrangement, the beam was composed of 25% high-strength concrete and 75% normal-strength concrete. In the second arrangement, the beam had an equal amount of high-strength and normal-strength concrete. Lastly, the third arrangement was composed of 75% high-strength concrete and 25% normal-strength concrete.

Testing for this experiment was done by performing tests on flexure loading using a four-point loading test. Key parameters like ultimate load, formation of crack, crack propagation, and deflection at midspan were measured and evaluated. Based on the results, it can be concluded that adding more percentage of HSC in the tension zone leads to improved load-carrying capacity and minimized deflection. From this research, it is evident that the use of layered concrete is a good strategy in optimizing the performance of structures by minimizing the consumption of materials.
