Concrete Curing Time And Duration - Pro Civil Engineer . Com

In normal concrete work, the maximum compressive strength that can possibly be obtained is generally reckoned to be about 7,500 psi for a 28-day cylinder. Curing Time for Concrete. In standard industrial cases, full strength concrete is recognized at 28 days. At seven days, you should have concrete that is cured to 70% full strength or greater.
