[摘要] 盐冻破坏是我国北方地区混凝土过早破坏或耐久性失效的重要原因。设计了纤维混凝土在盐冻环境下的耐久性试验，研究不同掺量聚丙烯纤维对混凝土抗盐冻性的影响。通过试验得出聚丙烯纤维混凝土在盐冻作用下的动弹模量、质量损失、抗折强度以及劈裂抗拉强度的变化规律，分析了聚丙烯纤维掺量对混凝土抗冻性的影响。

Abstract: Deicing salt destruction is the important reason of the concrete premature damage or the failure of durability of concrete in the northem China. The design of fiber concrete in deicing salt environment under the action of an endurance test was introduced, the resistant of deicing salt of properties by different dosage of polypropylene fiber concrete was studied. Through the experiment, it is concluded that the polypropylene fiber concrete in deicing salt under the action of dynamic modulus, quality loss, the flexural strength and splitting tensile strength, the resistant of deicing salt of properties by different dosage of polypropylene fiber concrete is analyzed.
