ASTM standards Usually we specify the 28-day strength, that is, the compressive strength after 28 days' moist cure at 73 ˚F.

It Depends on the hydration process of the concrete.

95 - 98 % concrete strength is 28 days.

The full strength of concrete is 3 years.

Because the hydration process of concrete 100 % will be 1 year.
