摘要
对在混凝土中掺入聚丙烯纤维的工艺,以及掺入聚丙烯纤维后对混凝土性能的影响进行了试验研究.室内试验及工程应用结果表明,聚丙烯纤维混凝土能有效地减少混凝土塑性收缩裂缝,明显改善混凝土抗变形能力,有利于提高混凝土的耐久性.
Techniques of adding polypropylene fiber(PPF) into concrete and influences of the polypropylene fiber on concrete properties are studied through tests. Results of laboratory tests and application show that the polypropylene fiber reinforced concrete(PFRC) can reduce plastic shrinkage cracks of concrete, and can improve the deformation resistance property and durability of concrete greatly.
