Abstract

This study aimed to develop and evaluate of fire resistant covering systems for HSC(high-strength concrete) column which has mainly constructed with ACB(Aerogel Composite inorganic Blanket) and FGB(Fire protective Gypsum Board). The ACB-FGB fire resistant covering system showed that it clearly secure the fire resistance performance for HSC column when the reinforcing measures had achieved for four cross-sectional edge sides of member and the system is well continued during test period with no significant deformation or seperation. It was checked out the 20 mm thinkness covering system consist of ACB(5 mm)+FGB(15 mm) can have a rating of 3 hour-fire resistance performance adequately; 20 mm thinkness is only 50-70% level of exsisting gypsum board covering systems that can show an equivalent capacity.

본 연구는 에어로젤 복합 무기질 블랭킷과 석고보드를 이용한 고강도콘크리트 기둥 피복시스템 개발 및 그 성능 평가를 목적으로 하였다. ACB(에어로젤 복합 무기질 블랭킷)-FGB(방화석고보드)피복시스템은 기둥 네 모서리 부분의 변형이나 탈락이 없도록 보강되면 구조체의 내화성능을 충분히 확보할 수 있음이 확인됐다. ACB(5 mm)+FGB(15 mm)구성의 20 mm 피복으로 3시간 내화성능이 확보될 수 있음을 확인하였는데, 이 피복시스템은 동등 성능의 기존 석고보드 내화피복의 50-70% 두께 수준이다.
