摘要
针对寒区桥面铺装这一特殊应用领域要求,对不同掺入量的聚丙烯纤维混凝土进行冻融循环及冻融—氯盐共同作用下耐久性试验,研究低掺聚丙烯纤维对寒区桥面铺装混凝土性能的影响。试验结果表明:低掺聚丙烯纤维桥面铺装混凝土可提高抗冻性能和抵御氯盐侵蚀能力,防止钢筋锈蚀,增强混凝土耐久性。
By testing the freeze-thaw cycle and frost thawing-chlorin chlorine salt combined activate for the polypropylene fiber concrete(PFC), the performance on polypropylene fiber concrete to bridge deck waterproof surfacing has been studied. The test results indicate that the polypropylene fiber concrete(PFC) improve reinforcement corrosion and concrete durability.
