굴 패각을 활용한 내화모르타르의 고온수열에 따른 성분변화에 관한 연구

Study on high-Heated according Change of Fireproof Mortar Using Oyster Sell

IN order to use it for high-temperature fire, Fireproof boards mainly composed of Ca and Mg used. Korea does not have a fireproof board for explosive high temperatuer fire in tunnel, and it is applying existing fireproof coating. However, when a high-temperature fire(1350℃)with explosion occurs, it can not sustain its strength and can not be destroyed to have fire resistance. Each year, more than 100,100tons of wastes are produced by using Ca as an oyster shell. In this study, we try to determine whether or not to reuse the heat-heated fireproof board.
