Abstract
The buildings constructed with steel structure is coated with certified Sprayed Fire Resistive Material(SFRM) to resist from fire. All the building materials lose their initial performances as time passes, so they need durability. In a previous Paper(Journal of The Korean Society of Hazard Mitigation in April 2014 to be posted) covered standardization of the methods for assessing the durability of SFRM. In Korea, more than 90 percent of SFRM are used indoors. So their fire performance were tested under indoor conditions before and after accelerate wet/dry cycling and temperature cycling to standardize the methods for assessing their durability. This paper is a follow-up study of the previous paper, that will be suggested the final draft based on validation tests and review the details for creating the Korea Industrial Standard.
Key Words: Sprayed Fire Resistive Material(SFRM); Durability; Acceleration test method; KS; Fire Resistance
요지
철골 건축물은 화재시 안전확보를 위하여 국가인정을 취득한 내화뿜칠재로 피복을 한다. 내화뿜칠피복재 역시 다른 건축자재와 같이 시간이 경과함에 따라 초기의 성능이 저하되어 내구성 확보가 필요하다. 이전 논문(한국방재학회논문지 2014년 4월 게재, 1보)에서는 내화뿜칠재의 90% 이상이 실내에서 사용되는 현황에 맞추어, 냉온조건, 건습조건에 따른 내화뿜칠피복재의 촉진내구성 평가방법을 제시하였었다. 이 논문은 이에 대한 후속논문으로써, 시험방법을 국가표준(KS)으로 작성하기 위한 검증시험과 세부사항 검토결과를 종합하여 제안한 최종안에 대한 내용을 담고 있다.
핵심용어: 내화뿜칠재; 내구성; 촉진시험방법; 국가표준; 내화
