To explore the research progress of bonding performance between rebar and concretesubjected to multi-factor composite environments,the bonding characteristics,bonding strength and bonding stress prediction formulas of reinforced concrete under monotonic and repeated loads were summarized and analyzed.Different environments such as freeze-thaw cycles,dry-wet cycles,chlorine salt attack,sulfate attack,carbonization and continuous loads were considered.The reasons affecting the bonding properties of reinforced concrete under different environmental factors were sorted out and explained.Combined with the literature and the practical needs of the project,the further problems to be solved in the research on the bonding properties of reinforced concrete under muti-factor composite environments are pointed out.At last,the conclusion was put forward that due to the complex effects of muti-factor compound environment,although some rules had been found in the existing studies,the conclusions were scattered and different,and further scientific research is needed.
