摘　　要：该文研究聚丙烯纤维对混凝土性能的影响,结果表明,0.75 kg/m3掺量的聚丙烯纤维增强混凝土劈拉强度、抗折强度、抗裂性、抗渗性和抗冻性较普通基准混凝土明显提高,工作性、抗压强度和回弹模量略微降低。The effect of polypropylene fiber on the properties of concrete was studied in this paper. The results showed the splitting strength, flexural strength, anti-cracking, impermeability and frost-resisting durability were improved with 0. 75 kg/m^3 polypropylene fiber content, while the workability, compressive strength and elastic modulus decreased.

关 键 词：聚丙烯纤维 工作性 抗裂性 耐久性
