聚丙烯纤维混凝土及其有关问题探讨

Inquiry into certain problems about the polypropylene fiber reinforced concrete

在混凝土中掺入适量的聚丙烯微纤维,能改善混凝土的脆性破坏特征,减少混凝土的收缩裂缝,提高混凝土的韧性,抗冲耐磨性,还能提高混凝土的抗渗、抗冻等特性,是实现混凝土高性能化的很好途径。

The polypropylene fiber can lessen the shrinkage crack of concrete, enhance its toughness and the ability of resisting crack, impact and fatigue; improve its brittleness destroy character and polypropylene fiber can also improve the ability of resisting leakage, frostbite etc so appending polypropylene fiber in concrete is a good way to make the concrete be high performance.
