Why Won't the Concrete Dry?
But well-cured concrete also has a disconnected void system that slows the moisture-vapor emission rate. So drying well-cured concrete requires removing a small amount of water, but that water must exit the concrete through a winding, constricted path. In concrete where the duration of curing is short, the reverse is true.
