Curing of concrete is an important part of the construction process because it affects the durability of concrete. However, unexpected accidents may shorten the curing period or cause the concrete surface to dry out during the curing period, resulting in a loss of durability. In this cases, it is expected that the concrete surface can be re-wetted to restore its quality. In this study, the quality changes of concrete surfaces were quantitatively evaluated using an air permeability test after re-wet curing the concrete with different initial curing periods of concrete. The results of a quantitative study of the resistance of concrete to penetration of chloride ions by re-wet curing are also reported.
