摘要
分析聚丙烯纤维对混凝土性能的改善机理。通过工程实例和试验成果,阐述聚丙烯纤维混凝土的性能指标。表明聚丙烯纤维混凝土具有良好的抗冲耐磨性能和抗裂性能,可较好地应用于船闸输水廊道等处于高速、紊乱、含沙水流区。
This paper analyzes the improvement mechanism of concrete performance by polypropylene fiber. Based on engineering instance and experimentation, the performance indices of polypropylene fiber concrete are expatiated. It is proved that polypropylene fiber concrete performs well in resisting impact, abrasion and crack, and thus well applicable in sandy flow region characterized by high speed and turbulence, such as the filling ＆ emptying culvert of shiplock, etc.
