聚丙烯纤维对水工混凝土耐久性能的影响

The impact of polypropylene fiber to the durability of hydraulic structure concrete

在水工混凝土中掺入聚丙烯纤维,能够降低混凝土的干缩率,减少并延缓混凝土开裂;同时可以提高混凝土的抗冻和抗渗等耐久性指标。

The hydraulic concrete mixed with polypropylene fiber, can reduce the shrinkage rate of concrete, decrease and delay the concrete cracking, raise the concrete antifreeze durability and impermeability, and other indicators as well.
