Abstract
The effect of Superabsorbent polymer (SAP) admixture in patch repair materials on the adhesion to the base concrete and the protection performance of reinforcing bars was investigated. In the experiment, one side of RC joint specimens were exposed to water. Water leakage from the interface between the base concrete and the repair material was reduced in the SAP specimen compared to the conventional Polymer modified mortar specimen. In addition, the half-cell potential and polarization resistance of the SAP specimens showed noble and high values, respectively, indicating the inhibition of corrosion of reinforcing bars.
