摘要
FRP筋除具有抗拉强度高、疲劳性能好、松弛率小等优良力学性能外,特殊环境下的耐腐蚀性能也明显优于钢筋,成为解决钢筋锈蚀问题的最佳选择。本文在系统地查阅国内外代表性研究文献的基础上,对FRP筋的耐酸碱盐、潮湿、紫外线和耐温耐火性能进行了研究和总结,并对今后拟开展的研究工作提出了建议。
FRP provides high strength,good fatigue properties,low relaxation rate,excellent corrosive resistance to steel in corrosive environments,etc.,and being taken as an alternative reinforcing material for steel to the corrosion problem.This paper describes the newest research work on the resistant performances of acid,alkali,salts,moisture,ultraviolet rays,temperature and fireproof of FRP tendons at home and abroad.Finally,advices for advanced research are provided.
