Experimental Study on Bond Performance between CFRP and Concrete in Seawater Environment

In order to obtain the variation of the interface bond performance between CFRP and concrete in seawater environment,the single shear test is adopted to study the bond performance of CFRP-concrete with the emphasis on the effects of concrete compression strength,width of CFRP,bond length of CFRP and seawater erosion time.The test results show that the interface bond strength between CFRP and concrete has a slowly downward trend with the increase of erosion time;The slip value corresponding to the inflection point of load-slip curve and the maximum slip value have a certain increase;The shear stress distribution curve can show the interface debonding process between CFRP and concrete;The concrete compression strength has a small impact on the bond strength.
