Abstract

Fiber reinforced polymer ( FRP) rods have a broad application in civil eng ineering field used as a material substiting steelbars. Based on the domestic and abroad research, the durability of the fiber reinforced polymer (FRP) rods undermultifarious environmental conditions is summarized in this paper, and the effect of environments such as temperature, humidity, corrosion from acid, alkaline and salt solutions on durability performance of FRP materials as well as the degradation of the bond characteristics between FRP rods and the interface of concrete caused by the acceleration environment test are mainly discussed. The results indicate that the environmenta lconditionsm entioned above affect FRP rods and bond characteristics between FRP rods and the in terface of concrete.In addition, a relatedmodel predicting the influence on durability of FRP rods in alkaline solutions is given and future study trend on durability of FRP rods is presented
