To investigate the bond performance between seawater sea-sand alkali activated concrete (SSASC) and carbon fiber-reinforced polymer (CFRP)/glass fiber-reinforced polymer (GFRP) bars, center pull-out tests were carried out at different FRP bars, FRP bars diameters, bond lengths, concrete strengths, and concrete curing ages. Based on the statistical analysis of existing experimental data, the bonding performance between alkali activated concrete (ASC) and FRP bars is significantly better than that of ordinary Portland concrete (OPC). The bond strength can be predicted by the corresponding empirical model. The results show that the bond strength decreases with the increase of FRP bars’ diameter and bond length, and there is no significant change as the diameter changes. Concrete ASC30 is mostly destroyed in pull-out failure, while concrete ASC60 is mostly destroyed in splitting/reinforcement fracture failure, and the concrete with a higher strength also has a higher bond strength. The bond strength increases with the increase of curing age. The bond strength between OPC and FRP bars is less than that of ASC. In addition, the bond strength predicted by the empirical model is in reasonable agreement with the experimental data.
