摘　　要：研究了改性聚丙烯纤维复合矿物掺和料对混凝土抗压强度、抗裂性能和耐久性能的影响.结果表明,在混凝土中加入改性聚丙烯纤维复合矿物掺和料可以在不影响强度的情况下明显减小混凝土的开裂面积,而且对其耐久性能有不同程度的改善作用.The influence of modified polypropylene fiber and compound mineral admixtures including fiber on concrete mechanical properties, anti-cracking and durability was studied. It is proved that adding modified fiber into the concrete can reduce the area of concrete cranny, but not weaken its mechanical properties, and can improve its durability.

关 键 词：改性聚丙烯纤维 抗裂 耐久性 复合矿物掺和料
