Curing of Concrete

[msm859]

The hardness of concrete is typically stated based on a 28 day cure. You should not subject it to heavy use before then.

I also pour concrete decks, and concrete is safe to walk on after about 4-8 hours after broom finish and you may put furniture on the deck just to be safe 3-4 days later and it takes 27 DAY to reach its MAXIMUM HARDNESS STRENGTH
