재하 및 비재하 내화 실험을 통한 고강도콘크리트의 내화성능에 관한 실험적 연구

A Experimental Study on the Fire Resistant Performance of the High Strength Concrete with Loading and Unloading test

Recently, the higher buildings are, the stronger concrete are used. Ultra high strength concrete have the possibility of spalling when a fire breaks out. so the fire-resistance performance is necessary to use the ultra high strength concrete on the high-rise building. On this study, the heating test for the concrete with loading/unloading is performed for ultra high strength concrete using nylon fiber. The heating test followed by ISO-834 heating curve on the real-size specimen and the strength of concrete are 60, 80, 100, 200 MPa.
