聚丙烯纤维混凝土在桥面连续及伸缩缝中的应用

Application of Polypropylene Fiber Reinforced Concrete to the Joint of Continuous Slab-deck and the Expansion Joint of Bridge

探讨聚丙烯短纤维掺加于普通混凝土中改善混凝土抗冲击、抗冻等性能的作用机理 ,结合实例介绍了聚丙烯纤维混凝土在桥面连续及伸缩缝中的应用。

Characters of concrete such as impact resistance and frost resistance can be improved if the polypropylene fiber is mixed into the plain concrete. Combined with the concrete example, the applications of polypropylene fiber reinforced concrete to the joint of continuous slab-deck and the expansion joint of bridge was introduced.
