摘　　要：按照国际标准测试了纤维自密实高性能混凝土(FRSCHPC)的工作度、强度及韧性,研究了FRSCHPC在混凝土结构加固与补强中的应用,分析对比了不同纤维含量的FRSCHPC作为补强材料与原结构共同工作的性能.试验结果表明,低收缩率、徐变率及较高强度、韧性的FRSCHPC与原构件具有相同受荷性能,是一种行之有效的结构补强材料.According to different international guidelines, the tests of workability, strength and toughness of the fibre reinforced self compacting high-performance concrete （FRSCHPC） were completed. Based on the test results, the application of FRSCHPC as the repair material of the concrete structure was investigated and the working behavior of different repair materials together with the original concrete structure was analyzed and compared. Experimental results show that the FRSCHPC, with the low shrinkage and creep ratio, high strength and toughness, and the same load-bending ability with original members, can be suitable for the repair application of the concrete structures.
