Abstract

The concrete strengthened was placed in the natural,water,acid,alkaline and carbonation environments for 14 d and 56 d.Effect of erosion medium on adhesive property between the concrete strengthened and CFRP was researched by measuring the normal tensile strength and observing the destructional forms between concrete and CFRP.The results showed that the normal tensile strength was obviously reduced by acid environment and followed by carbonation environment,alkaline environment,water environment after 14 d.The tensile strength was also obviously reduced by acid environment and followed by alkaline environment,water environment after 56 d.Carbonationt environmen increased the novmal tensile strength between the concrete strengthened and CFRP.After 14 d destructional forms of the concrete strengthened with CFRP only in the acid environment was the bond failure between concrete and CFRP;and under natural and carbonation environments concrete was damaged due to tension stress.This illustrated that acid environment greatly affected the adhesive property between concrete and CFRP.After 56 d destructional form of the concrete in water,acid,and alkaline environments was the bond failure between concrete and CFRP and under other environments concrete was damaged as a result of normal tension stress。This showed that erosion environment more and more greatly affected the adhesive property between concrete and CFRP with increase of ersion time.
