短切聚丙烯纤维对透水混凝土的性能影响
Effect of Chopped Polypropylene Fiber on the Performance of Pervious Concrete
摘要: 以短切聚丙烯纤维作为增强材料，设计不同尺寸和掺量的短切聚丙烯纤维透水混凝土(CPPFPC)，通过试验分析了不同尺寸、不同掺量短切聚丙烯纤维对透水混凝土抗压强度、抗折强度、透水性能及抗冲击性能的影响，结果表明：各尺寸短切聚丙烯纤维掺量为0.2%时，透水混凝土的综合性能较好；短切聚丙烯纤维对透水混凝土的抗压强度、抗折强度及抗冲击性能均有提升，抗折强度提升效果相对于抗压强度较弱，而抗冲击性能提升较为显著。
Abstract: Using the chopped polypropylene fiber as the reinforcing material, different sizes and dosages of chopped polypropylene fiber permeable concrete (CPPFPC) were designed. The influence of different sizes and dosage on the compressive strength, folding strength, water permeability and impact resistance of permeable concrete were analyzed through experiments. The results show that when the amount of chopped polypropylene fiber of each size is 0.2%, the comprehensive performance of permeable concrete is good; chopped polypropylene fiber improves the compressive strength, folding resistance and impact resistance of permeable concrete. The improvement effect of the antifolding strength is weak compared to the compressive strength, and the impact resistance performance is more significantly improved.
