Evaluation on High-Temperature Mechanical Properties of 150MPa Concrete Mixed with PP and NY Fiber

PP, NY섬유를 혼입한 150MPa 콘크리트의 고온역학적 특성

Ultra high-strength concrete can prevent spalling by mixed ratio of PP and NY fiber. However, there is a lack of research on the deterioration of strength due to changes in mechanical properties after spalling prevention. In this study, the effect of high temperature on the mechanical properties of 150MPa concrete mixed with PP and NY fiber was evaluated. As a result, mixing PP and NY fiber is judge to be little effect on the mechanical properties of the 150MPa concrete at high temperature.
