Concrete Wall Panel From Styrofoam Waste With Wiremesh Reinforcement

Wall is part of the room divider that inlluence the structural aspects of weight and rigidity. BAsed on these reasons we need wall that has some characters such as light but also environmentally friendly. Manufacture of lightweight concrete wall of styrofoam is an effort to utilize waste of styrofoam. Styrofoam concrete wall panel study using specimens measuring length 1000 mm. width 300 mm and 70 mm thick, with the addition of 15 mm thick layer of plaster/mortar on both sides. The composition of 1 m3 styrofoam concrete consisted of 300 kg cement with 0.5 water-cement ratio. 60% styrofoam, and 40 % sand. Testing and research produced the following data : the average of flexural strength specimens without wiremesh : 3,77 MPa. The average flexural strength specimens with wiremesh : 5,84 MPa. The results showed that the strengthening of wiremesh increased the flexural strength of the panel
