Abstract

This review summarizes the effects of polymer-modified interfacial agents on the bonding performance between new and old concrete layers. It discusses the advantages and disadvantages of various polymers used in interfacial agents from a materials perspective and elucidates the mechanisms by which polymers enhance interfacial bonding. The anchoring effect of fibers and the film-forming action of polymers synergistically improve the bonding strength and toughness of the material. Despite the promising application prospects of polymer-modified materials in concrete repair and strengthening, challenges remain, such as insufficient early strength and variability in bonding performance after modification with different polymers. Therefore, a systematic and standardized investigation into the impact of polymer type and dosage on bonding performance is necessary.
