산업부산물을 활용하여 친환경적인 재자원화를 도모하고 화재에 대비한 콘크리트의 내화성능 및 폭열을 방지하고자 산업부산물(플라이애시, 고로슬래그 미분말)과 섬유(PVA섬유, 강섬유)를 혼입한 내화모르타르의 압축강도 잔존률을 비교분석하여 내화모르타의 역학적 특성을 파악하고, 내화소재 개발에 대한 기초적인 자료로 활용하고자 한다.

In this study, it was developed hybrid fiber reinforced concrete using ground granulated blast furnace slag, the industrial wastes, and recycled aggregate. As a result of experiments on improvement of performances of eco-friendly buildings utilizing recycled resources (recycled coarse aggregates and ground granulated blast furnace slag), the following conclusions are drawn. As hybrid fiber(PVA Fiber+ Steel Fiber) was mixed with the concrete in which the replacement was conducted with recycled coarse aggregates and ground granulated blast furnace slag, the structural performance were increased.
