摘 要：When fire occurs in a concrete structure, it is hard to extinguish it because of its unique form and location, which results in a very high internal temperature of the maximum 1400℃.Due to the fine structural characteristic of concrete, the structure is likely to suffer fatal damages such as the reduction of resisting force and the damages to the cross section caused by explosive fracture.In this research, the author tested the effect of fire on structures by using fire boards with perlite-added silicone and confirmed that the fire resisting capacity varies according to the weight ratio of the addition agent, which shows what effect perlite has for the pyrolysis process.A fire resisting capacity test was also carried out by attaching a silicone composite fire board to a real size specimen.As a result of the test carried out by installing the fire boards with different thickness by section, most fire boards had excellent fire resisting capacity, and fire boards with 20mm or more thickness had also excellent fire resisting capacity.
