COMPOSITION FOR FIRE RESISTANT BOARD CONTAINING PHASE-CHANGE MATERIAL FOR PREVENTION OF HIGH STRENGTH CONCRETE EXPLOSION

摘要

A composition for fire resistant board containing the phase-change material for prevention of high strength concrete explosion is provided to prevent the explosion of the concrete member surface by the fire. A composition for fire resistant board comprises the ground granulated blast-furnace slag, the copper slag, the alkali irritant and the phase change material. The phase change material is contained by 0.1~0.2 weight% about the whole total weight of composition. The ground granulated blast-furnace slag is contained by 20~50 weight% about the whole composition total weight. The copper slag is contained by 40~70 weight% about the whole composition total weight. The alkali irritant is contained by 2.0~7.5 weight% about the whole composition total weight.
