This study investigates performance of fire resistance of HPC with the contents of polypropylene(PP) and polyvinyl alcohol(PVA) fiber, respectively. The experimental results shows that increase of fiber contents, regardless of fire type, exhibited low fluidity and air contents. In the case of compressive strength, on the other hand, all specimen had more than 50MPa of compressive strength. For the properties of spalling appearance, serious spalling failure occurs with plain concrete, which caused exposure of re-bar, while HPC containing fiber had favorable prevention of spalling. Residual compressive strength maintained more than 70% of original strength, regardless of fiber contents,
