【摘要】 FRP(纤维增强复合材料)近年来在混凝土结构加固中得到了广泛的应用,FRP加固混凝土结构的耐久性能也日益受到人们的重视。在我国青海及北方许多地区冻融循环作用对混凝土结构的耐久性能有较大的影响,采用FRP加固后混凝土结构的冻融耐久性如何已成为一个十分重要而迫切的研究课题。综述了近年来国内外有关FRP加固混凝土结构冻融耐久性的研究成果,对今后的研究工作提出了建议,以期促进FRP这一高性能新型材料在青海等日夜温差较大地区的推广与应用。更多还原

【Abstract】 In recent years,FRP(fiber reinforced polymer/plastic)has been widely utilized for strengthening concrete structures.More and more attention has been paid on the durability of the strengthened concrete structures by FRP. The effect of freeze and thaw has a great influence on the durability of the concrete structures in Qinghai Province and many areas of Northern China.The research in the durability of the strengthened concrete structures by the FRP under the effect of freeze and thaw is still less related to.An overview involves the achievements in durability under the effect of freeze and thaw by various researchers all over the world.We try to put some advices in the further researching in the durability of FRP reinforced structures under the effect of Freeze and Thaw.This paper is mainly aimed at promoting future research and application of FRP in Qinghai Province and other areas which are deeply influenced by the effect of day and night temperature difference.更多还原
