Jul 27, 2021Concrete curing and concrete drying are two different processes. Curing is the process of hardening that begins immediately after the concrete is poured. The concrete curing process is usually mostly complete after 28 days or so. However, the concrete will continue to harden further for a significant amount of time after that.
