Abstract

•Patch repair always leads to corrosion increase of the active steel within the remaining substrate concrete.•SACP should be preferentially placed within the substrate concrete (and not within the new concrete of patch repair).•Contaminated concrete should be removed all around the steel for a sustainable repair.•The ratio between macrocell current and overall current of SACP in reinforced concrete is far from that in maritime field: taking into account the electrical resistivity of concrete allows to better estimate the SACP lifetime.
