聚丙烯纤维混凝土在集装箱码头上的研究与应用

Research and Application of Polypropylene Fiber Concrete in Container Terminal

通过对码头面层的龟裂和裂缝原因进行的调查分析,并通过对混凝土面层防止龟裂的四种方法的现场试验,得出掺聚丙烯纤维对混凝土面层龟裂有较好的性价比。在此基础上,对聚丙烯纤维混凝土特性进行了系统的试验研究,并在上海外高桥港区三期、四期和五期码头面层中成功应用。

Based on the analysis of the investigation on reason of cracks in terminal facing layer concrete and action mechanics of fiber in concrete, and through site tests about anti-cracks in concrete facing layer by 4 methods, this paper draws a conclusion that we can get higher performance-price ratio by adding polypropylene fiber in concrete facing layer. Furthermore, systematic experimental study was conducted on the characteristics of polypropylene fiber concrete, which was successfully applied in terminal facing layers of Shanghai Waigaoqiao Port Area Phase III, Phase IV and Phase V projects.
