Technically, concrete never stops curing. In fact, concrete gets stronger and stronger as time goes on. But, as far as we're concerned, to reach a practical strength, most industrial concrete mixes have a 28 day curing period. After 7 days, the concrete will have gained around three quarters of its compressive strength, but you should refrain ...
