摘要
钢筋锈蚀是混凝土结构面临的主要问题,纤维增强聚合物(FRP)筋代替钢筋增强混凝土构件解决锈蚀问题已成为研究的热点.但FRP筋的耐久性能与材料的组成、性质和筋与混凝土间的相互作用等均有关系,其耐久性腐蚀机理较复杂.综述了FRP筋在温度、水分、酸碱环境以及紫外线作用下的耐久性能研究进展和相关研究成果,为以后FRP筋性能的研究提供参考.
Taking the place of reinforcing bar, the fiber reinforced polymer (FRP) rebar is used to reinforce the concrete member is a feasible way to solve the main problem of reinforcing bar corrosion for concrete structures. However, durability of FRP rebar is related to material composition, properties as well as bar-concrete interaction, and its durability corrosion mechanism is complex. The research status of durability of FRP rebars under temperature, moisture, acidic and alkali environment and ultraviolet exposure are summarized, which would provide a reference for the future study.
