Abstract

With the wide use of FRP strengthened structures,the problem of their durability has been highlighted and concerned.The durability of adhesive property between CFRP and concrete is as important as that of FRP.Light aging(especially UV light) is one of the factors that influences the durability of adhesive property of CFRP and concrete.The influence of UV light on tow kinds of the adhesive specimens of FRP and concrete bonding property was conducted.The change tendency of mechanical behavior of CFRP and concrete was investigated and the test results were analyzed.The adhesive properties of CFRP and concrete with and without protected were comparion.The results showed that the influence of UV light on adhesive property was great,and protection can slow the deterioration of adhesive strength of CFRP and concrete.
