To ensure the longevity and endurance of the buildings, Lightweight Panels have been applied a lot, as well as Rahmen and Flat Slab. Among the Lightweight Panels, the one with EPS(Expended Polystyrene), which reinforces weakness in bending strength that exists by attaching CRC(Cellulose Reinforced Cement board) and Mg(Magnesium board) on both sides of the panel, has widely been used. From the complex panel attached, with the CRC and Mg on both sides of the panel, you could expect enhanced fire resistance as well as an improvement in bending strength. Hereupon in this research, I have reviewed the heat-proofing performance of the types of lightweight partitioning boards with EPS and reinforcement. Accordingly I would like to suggest the basic data necessary for evaluating the possibility of using these architectural materials in residental buildings. In my research results, the boards fire resistance performance improved as each board became thicker. There is no significantly different change in the heat-proofing performance of the CRC (THK 3.2) regardless of the attachment, but it has demonstrated improved fire-resistance performance compared with the Mg. Although there is some difference in the fire resistance performance of each panel 50mm thick, it appears that this panel is unsatisfactory with the conditions of acceptable fire resistance structures required for its use in multi floor buildings. |
