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微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的力学指标纤维的作用相差很大。笔者尝试从高温中和高温后PP纤维在混凝土中的力学行为着手分析其在混凝土高温后不同力学性能的贡献。
Fire behavior of high performance concrete is less than common concrete ,it is an efficient means to resist crack when adding polyproylene to concrete. Based on large numbers of experiments, the effect of polyproylene on mechanical property of high performance concrete after high temperature is studied,and great different is found in difference mechanical property. A trying analysis of Polyproylene's different contribute to compressive and flexural property of concrete after high temperature is given, in terms of the behavior of polyproylene under and after elevated temperature.
