  • Flexural capacity of composite concrete beams with normal-styrocon (addition of 30% styrofoam), have the ability to restrain ultimate load of 34.5 kN, and the addition of expanded polistyerene styrocon on tension area has resulted in higher elongation than normal concrete, so it has better flexibility as well.
  • Reinforced concrete has been used widely to accelerate infrastructure development. Concrete material is formed by mixing cement, aggregate, and water. Aggregates generally use gravel and crushed stone, which is obtained from the exploitation of natural materials and will have an impact on the environmental damage. Therefore, creative effort is needed, so that concrete material can be used as efficiently as possible. Based on the hardened concrete properties and from the viewpoint of engineering mechanics, concrete structures in a flexural system will occur tensile and compressive action to produce a resistant moment, thus concrete on the tension zone does not contribute directly in resistant moment. Volume of concrete in the tension zone can be reduced by utilizing Styrofoam waste as filler to produce a concrete material containing granules Styrofoam, hereinafter called Styrofoam filled concrete (SFC). Reinforced concrete beams using SFC-50 (Styrofoam 50% by volume), bending capacity in the tension zone decreased by 40%. Consequently, SFC affects the compression strut on the beam bending action. Therefore, it needs compression strut action to replace compression strut weakening in SFC by using truss system reinforcement. Truss system reinforcement is used to take advantage of truss action in improving the bending capacity of beams using SFC. The objective of this study is to determine the bending capacity of beams using SFC on the tensile zone and truss system reinforcement.
