Concrete Curing Guide | Total Concrete Ltd
Concrete never stops curing; it gets stronger and stronger as time goes on, but the curing process is the period in which the concrete reaches its rated compressive strength. After this time, while the concrete is still curing, it's a case of diminishing returns. Most ready mix concrete will reach its full strength after 28 days.
