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

재하 및 비재하 내화 실험을 통한 고강도콘크리트의 내화성능에 관한 실험적 연구

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.
