The standard cube pullout tests were conducted to study the bond behavior between the ribbed glassfiberreinforced polymer (GFRP) bars and concrete made with different raw materials and different strengths. The results showed that the use of recycled coarse aggregate (RCA) decreased the bond strength while seawater seasand (SS) had nominal effect on that of concrete. Different concretes shared similar bond stressslip curve. Similar with natural aggregate concrete (NAC), the bond strength between seawater seasand recycled aggregate concrete (SSRAC) and the ribbed GFRP bars improved with the increase of compressive strength of concrete. Furthermore, four bond stressslip models were selected to fit the experimental curves and the results showed that all the four models fitted the experimental curves well and the model proposed by Malvar had the highest coefficient of determination.
