摘　　要：研究了碳纤维对混凝土力学性能及耐酸雨腐蚀性的影响。研究表明,碳纤维的理想掺量为0.1%。碳纤维石粉混凝土的抗压、抗折强度及抗硫酸腐蚀性均优于普通混凝土和石粉混凝土,7d和28d的抗折强度均超过10MPa。碳纤维石粉混凝土具有优异的抗硫酸腐蚀性,可应用于酸雨地区的混凝土工程。The compressive and flexural properties, the sulphuric acid erosion resistance of carbon fiber concrete have been studied. The results show the ideal adding ratio of carbon fiber is 0. 1%. The compressive strength and flexural property, the sulphuric acid erosion resistance of the carbon fiber concrete are better than that of the ordinary and limestone powder concrete, and the 7d and 28d flexural strengths of carbon fiber concrete exceed IOMPa. The results reveal that carbon fiber concrete can be used in concrete engineering of the acid rain area.
