The minimum period for curing concrete to attain maximum strength is 28 Days. From the above graph, it is clear that concrete attains 50% of its design strength when it cured for 3-7 Days. 75% of Compressive strength achieved in 14 days and 90% of strength by 28 days as time goes on the strength increase gradually.

Actually, the crack is formed due to the heat of hydration in the structure (members) so this heat is reduced by curing.
