Abstract
The flammable exterior material installed on the outer wall of a piloti structure is a major cause of fire spread because such fires are transferred in a short time, and they cannot be extinguished after ignition. An external insulation system is composed of various materials; hence, individual fire safety must be secured for each component. This study performed the cone calorimeter and real-scale fire tests of BS 8414 for the adhesives used in construction (e.g., adiabatic system). The heat release rate for the organic adhesive was 17.5 MJ/m2, while that for the inorganic adhesive was 14.0 MJ/m2. The obtained results showed that only the inorganic adhesive passed the tests.

요지
필로티 구조의 외벽에 설치되는 가연성 외장재는 화재가 단시간에 전이되며 내부 착화 시 소화가 불가능하여 화재 확산의 주된 원인으로 대두되고 있다. 외단열시스템(EIFS) 경우 단일재료로 구성된 것이 아닌 다양한 자재들로 구성된 시스템인 만큼 각 구성요소 등에 대한 개별적인 화재안전성 확보가 이뤄져야 한다. 본 연구에서는 외단열시스템 등 건축용 접착제에 대하여 콘칼로리미터시험과 실대형 BS 8414의 비교시험을 실시하였다. 열방출률의 경우 유기접착제 17.5 MJ/m2, 무기접착제 14.0 MJ/m2로 나타났으며, 실대형 외장재 시험 결과, 무기접착제만 시험기준을 통과하였다. 접착제의 구별에 따라 열방출률 및 화재확산에 차이가 있다는 것을 확인하였다.
