摘　　要：通过在混凝土体系中单掺或混掺钢纤维、聚丙烯纤维、UF500纤维素纤维3种不同性质的纤维,系统的研究了3种纤维单掺或混掺对混凝土工作性、力学性能和抗渗性的影响特点和变化规律。结果表明,钢纤维和聚丙烯纤维有利于提高混凝土抗折强度,而纤维素纤维对混凝土抗渗性有较明显的改善效果;纤维混掺比纤维单掺能更大幅度的提高混凝土的抗折强度和抗渗性能。The influence of steel fiber, polypropylene fiber and UF500 cellulose fiber as well as their hybrid on workability, mechanical properties and impermeability of concrete are investigated systematically.Results showd that steel fiber and polypropylene fiber could effectively increase the flexural strength of concrete, and cellulose fiber better able to improve the impermeability of concrete.The concrete with hybrid fiber has better flexural strength and impermeability than the concrete with single fiber.
