聚丙烯纤维对混凝土抗震能力提高的探讨

A Study on the Polypropylene-Fibre Reinforced Concrete for the Improvement of Earthquake-Resistant Capacity

通过对普通水泥混凝土和聚丙烯纤维混凝土试件进行力学性能及耐久性的对比试验,分析讨论了聚丙烯纤维的掺入对水泥混凝土性能的影响。试验结果表明聚丙烯纤维混凝土具有良好的力学性能以及抗裂、抗渗透和抗冻融性能,从而能够在材料层面综合提高钢筋混凝土结构的抗震能力。

This paper examines experimentally the impacts of the incorporation of polypropylene fiber on concrete. A series of polypropylene-fiber reinforced concrete specimens are tested in comparison with ordinary cement concrete specimens for mechanical properties and durability performance. Test results indicate that the polypropylene-fiber reinforced concrete has good mechanical properties, crack resistance, impermeability and anti-freeze-thaw-cycle performance, which could improve the earthquake-resistant capacity of concrete structure in material aspect comprehensively.
