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 ultrahigh strength concrete on the high-rise building. On this study, the heating test for the concrete with loading/unloading is performed for ultrahigh 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.
