| Abstract |
|
In this study, in order to satisfy fire resistance performances during the fire, inorganic fire resistance cover materials and organic fire resistance cover materials have been tested for evaluating toxicity of combustion gas on fire resistance coating materials applied to main structure of the buildings. In the toxicity evaluation, NES 713 and BS 6853 have been applied. Major test variables are a spray coat, fire resistance gypsum board, fire resistance paints such as 1 hour fire resistance paint and 2 hours fire resistance paint by dividing them into inorganic and organic types. As a result of the evaluation on the toxicity, combustion gas has been highly generated in the organic cover materials compared to the one taking place in the inorganic cover materials. Because 2 hour fire resistance paints generate the largest combustion gas, it is considered that there might make an effort to reduce amount of cover by changing them to the fire resistance materials generating the most combustion gas. |

이 연구에서는 화재발생 시 요구내화성능을 만족시키기 위한 건축물 주요구조부에 적용하는 내화피복재의 연소가스 독성평가를 위하여 무기질계 내화피복재 및 유기질계 내화피복제를 대상으로 실험을 수행하였다. 연소가스 독성평가에는 NES 713, BS 6853을 적용하였으며, 주요실험 변수는 무기질 및 유기질 계열로 구분하여 뿜칠재, 방화석고보드, 1시간 내화도료, 2시간 내화도료였다. 독성평가 결과 유기질 내화피복재가 무기질 연소가스를 발생시키는 내화피복재로 피복물량의 저감을 위한 노력이 필요하다고 판단된다. |
