Daftar Isi:
- Walls are part of structure in vertical shape and function as room dividers as wellas theprotection maeans from outside condition (weather, sunlight, wind). It is also able to receive load (load bearing wall) from upper floor construction and distribute it to sloof and foundation. In its application, it is required to consider the influence of wall structure to the structural aspect due to its weight and stiffness. The heavier the wall, it is required for the wall to have several characteristics such as light, quick in concrete made from Styrofoam waste is one of the efforts to utilize it as alternative material in producing walls with wiremesh reinforcement. Styrofoam unit weight is very light which is between 13 g /m 3 and 15 kg/m 3 . This research was carried out by laboratory experiments trought material test stage, wiremesh, specimen making stage. Specimens werw made from sand, styrofoam, wiremesh and water as the bonding substance. They were made by mold basedonmeasurement. The wiremesh coupling on the both sides of the wall used connectors made from welded wiremesh. Then, the materials of the wall concrete (350 kg of cement, 80% Styrofoam and 20% sand at fas 0,43) were put into the mold. Concrete were let for 7 days and given with treatments to maintain their humidity. Then plastering process was taken. Treatment were continued for 28days for compression test and press flexible test (combination). The best press test result of 4,85 MPa was achieved in wallwith 80 mm core thickness and 10 mm plaster (T8.1), with 19,87 deflection at maximum loading, shortening of the collapsing pattern of to loading. Therefore, plaster tended to be pulled together with swelling core. This was possible because wiremesh was positioned in the center of the plaster and givenwith connector at the core side. Combination of press axial rest and flexible test on wall with 60 mm core thickness, 10 mm (TL8.1) plaster thickness resulted in flexible 22,10 MPa stress plaster at 26,86 mm maximum loading and collapsing pattern in the form of cracking around the loading point.
