Abstract

This study is a research about performance of fireproof board using industrial waste such as oyster shell and dry process bottom ash through the heating test and conclusions were obtained as follows. Test samples show back side temperatures as follows : in $300^{\circ}C$, $103.1{\sim}125.1^{\circ}C$, in $600^{\circ}C$, $201.1{\sim}210.1^{\circ}C$, in $900^{\circ}C$, $249.2{\sim}276.9^{\circ}C$. In the test, temperature increases of specimens of fireproof board are kept at certain temperatures hence it could be concluded that the specimens withstand high temperatures. According to the test, it could be concluded that fireproof board made by smaller particles shows better performance up to $600^{\circ}C$ while at higher temperatures, fireproof board made by bigger particles shows better performance. It is estimated that fireproof board made by particles of bigger size has more pore structure and it delays heat conduction.

본 연구는 산업폐기물로 발생되는 굴 패각과 건식공정 바텀애시를 골재로 활용하여 제작된 내화보드의 가열실험을 통한 성능에 관한 연구이며 다음과 같은 결론을 도출하였다. 전기로 가열실험을 통해 나타난 시험편의 이면온도는 $300^{\circ}C$ 가열상황에서 $103.1{\sim}125.1^{\circ}C$로, $600^{\circ}C$의 가열상황에서 $201.1{\sim}210.1^{\circ}C$로, $900^{\circ}C$의 가열상황에서 $249.2{\sim}276.9^{\circ}C$의 범위로 나타났다. 내화보드 시험편의 경우 일정온도상승 이후 유지되는 것으로 나타나 사용재료들의 경우 내화성능이 발휘되는 것으로 판단된다. 실험의 결과로 유추할 때, 입자의 크기가 작을 경우 $600^{\circ}C$까지는 내화성능이 상대적으로 우수하지만, 그 이상의 온도에서는 입자의 크기가 큰 경우 많은 공극을 포함하여 열전달이 지연되는 것으로 판단된다.
