Abstract:In this study, the application of electrodeposition method to repair reinforced concrete damaged by drying shrinkage cracks was investigated experimentally. Especially, it was clarified that electrodeposition had an effect on the reduction of water permeability and carbonation. The contents of this study were as follows; (1) the selection of external solution, (2) the influence of electrodeposition on the crack closure, and the effect of electrodeposition on the water permeability and carbonation restraints, (3) the influence of electrodeposition on the surface coating and minuteness on the non-cracked mortar, and the effect of electrodeposition on carbonation restraint, (4) the water permeability and adhesive strength after the electrodeposition. As a result, it was clarified that the electrodeposition led to improvement of mortar watertightness and carbonation restraints.
