EXPERIMENTAL STUDY ON EFFECT OF POLYPROPYLENE FIBER ON MECHANICAL PROPERTY OF HIGH PERFORMANCE CONCRETE AFTER HIGH TEMPERATURE
-
摘要: 高性能混凝土的抗火性能比普通混凝土差,在混凝土中加入聚丙烯纤维可作为一种有效的混凝土温差补偿抗裂手段。通过大量高温和力学试验,研究了聚丙烯纤维在不同温度下对矿渣和硅灰高性能混凝土的抗压、抗折的影响,并发现对不同力学指标的纤维的作用相差很大。Abstract: Fire behavior polypropylene fiber of high performance concrete is less than common concrete, it is an efficient means to resist crack when adding polypropylene fiber to concrete.Based on large numbers of experiments, the effect of polypropylene fiber compressive and bending properties of high performance concrete after high temperature is studied, and great difference in functions of the fibers with different mechanical indexes is found.
