—It is well known that the concrete in the tension zone is neglected in the design. Therefore, it is reasonable if the concrete on the tension zone uses a low compressive strength concrete by mixing them with the Styrofoam grains. The concrete that filled with the concrete grains is named with Styrofoam Filled Concrete (SFC). Styrofoam as waste can be used as a filler to reduce the volume of concrete, especially for areas where the concrete section is neglected in design. SFC used in this study were with 30% Styrofoam volume fractions. Results indicated that the BN had maximum flexural load of 38.8 kN, while BTL had decreased load of 24.2 kN and BTR of 36.0 kN, close to the normal beam specimen. Loading test of the BSC and BSCTR had maximum load of 38.2 kN and 48.3 kN, respectively. It can be concluded that the use of SFC in tension zone of the concrete beams showed a good agreement in performance compared to the normal reinforced concrete beams. The use of truss system reinforcement can increase the strength of the loading capacity of the beam is significant compared to the vertical reinforcement.
