Rebound hardness, gas permeability coefficient and water absorption rate of cut slides of concrete under different wet curing history at different depths on its surface were tested. The results show that the time of early wet curing is closely related to the spatial uniformity of the physical properties of concrete materials. The shorter the time of early wet curing, the lower the hardness (strength) of the surface layer concrete, and the worse the resistance to water and gas permeability, and the more significant the gradient of difference at different depths along the vertical concrete surface.
