摘要
纤维增强塑料筋(FRP筋)因其优异的力学性能及较轻的质量,逐渐成为替代传统钢筋的理想选择。尽管FRP筋在混凝土结构中展现出良好的性能,其耐久性仍然是工程应用中的关键问题。该文综述了纤维增强塑料筋的组成、优势以及在不同环境条件下的耐久性表现,重点探讨了酸碱、海洋盐离子、潮湿、紫外线和冻融等环境对FRP筋耐久性的影响。还分析了当前FRP筋耐久性研究中的挑战,并提出了未来的发展趋势和研究方向。随着技术的不断进步,FRP筋的耐久性有望得到有效改善,进一步推动其在混凝土结构中的应用。
Fiber-reinforced plastic reinforcement(FRP reinforcement)is gradually becoming an ideal alternative to traditional steel reinforcement due to its excellent mechanical properties and lighter mass.Although FRP bars show good performance in concrete structures,their durability is still a key issue in engineering applications.This paper reviews the composition,advantages,and durability performance of fiber-reinforced plastic reinforcement under different environmental conditions.It focuses on the effects of the environments such as acid and alkali,marine salt ions,humidity,ultraviolet rays,and freezing and thawing on the durability of FRP tendons.Finally,this paper also analyzes the current challenges in FRP reinforcement durability research and proposes future development trends and research directions.With the continuous progress of technology,the durability of FRP reinforcement is expected to be effectively improved,further promoting its application in concrete structures.
