混凝土结构用纤维增强塑料筋的耐久性评述

Research on Durability of Fiber Reinforced Plastics in Concrete Structures

钢筋锈蚀在房屋建筑、公路、桥梁、大坝等混凝土结构中大量存在,是混凝土结构耐久性破坏的主要形式之一。纤维增强塑料筋(FRP筋)作为一种钢筋替代材料在混凝土工程中的应用是解决钢筋锈蚀问题的新途径之一。本文对FRP筋及型材在多种环境条件下的耐久性问题的国内外研究进展现状进行了分析,并对今后FRP筋及型材的耐久性研究趋势作了展望。

Steel corrosion occured frequently for concrete structures in building, highway, bridge and dam structures, which was the most forms of concrete structure durable damage. Fiber reinforced polymer （FRP） applied as substitution materials provided a new way to dealing with steel corrosion in concrete structures. The paper was engaged in the analysis on the durability of FRP bars and materials under different environments at home and abroad, and offered the prospect for research trend of durability of FRP bars and materials in future
