摘要
纤维增强材料(FRP)在建筑结构加固修复及混凝土复合结构中广泛运用,特别在恶劣的服役环境中,常用纤维增强材料(FRP)代替钢筋或与钢筋混凝土结合使用,但FRP并非完全免疫于各类劣化环境,FRP-混凝土复合结构劣化环境下的耐久性越来越受到广大学者的重视。冻融作用对混凝土及FRP材料结构耐久性造成影响,进而影响FRP-混凝土复合结构的耐久性,FRP材料耐久性关系着整个复合结构的寿命问题。文章综述了近年来国内外学者对混凝土、FRP材料及FRP混凝土复合结构在冻融劣化环境下的耐久性研究成果,对今后的研究工作给出意见建议,以促进FRP在我国季节性冻土区的推广使用。
Fiber-reinforced materials(FRP)are widely used in the reinforcement and repair of building structures and concrete composite structures.Especially in harsh service environments,fiber-reinforced materials(FRP)are commonly used in place of steel bars or in combination with reinforced concrete,but the FRPsare not completely immune to all degraded environments;the durability of FRP-concrete composite structures under degraded environments has attracted more and more attention from scholars.Freeze-thaw affects the durability of concrete and FRP material structures,and then affects the durability of FRP-concrete composite structures.The durability of FRP materials is related to the life of the entire composite structure.In this article,the research results of domestic and foreign scholars on the durability of concrete,FRP materials and FRP concrete composite structures in freeze-thaw degradation environments in recent yearswere reviewed,and some suggestions for future research work were put forward,in order to promote the promotion and use of FRP in my country’s seasonal freezing areas.
