Progress of Studies on Durability of FRP Rods Used in Civil Engineering

摘要

Fiber reinforced polymer (FRP) rods have a broad application in civil engineering field used as a material substiting steelbars. Based on the domestic and abroad research, the durability of the fiber reinforced polymer (FRP) rods under-multifarious 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 environment a lconditions mentioned above affect FRP rods and bond characteristics between FRP rods and the inter face of concrete. In addition, a related model predicting the influence on durability of FRP rods in alkaline solutions is given and future study trend on durability of FRP rods is presented.
