Through measuring the anti-fight performance and fatigue property of polypropylene fibre concrete, this article makes dynamic performance of polypropylene fibre concrete. The result shows that the polypropylene fibre is important to the improvement of breaking strength of concrete, and the bending fatigue performance and impact toughness is improved substantially.%本文通过测定聚丙烯纤维网混凝土的抗击性和疲劳特性,对聚丙烯纤维网混凝土的动力学性能分析.结果表明聚丙烯纤维网掺入对提高混凝土抗折强度有显著作用,尤为突出的是其弯曲疲劳性能和冲击韧性大幅提高.
