Curing is one of the most important steps in quality concrete construction and one of the most neglected.
-
Effective curing is absolutely essential for surface durability.
-
Apply curing as soon after brooming and edging as it can be done without eroding the surface.
-
As long as concrete is allowed to cure it continues to gain strength and water tightness for years after it is placed.
-
Durability is the resistance of the concrete to freeze-thaw cycles, chemical attack, abrasion and other conditions of service.
-
Fresh concrete must be kept warm and moist until the mixing water combines chemically with the cement (hydration).
-
Without curing, the strength of the concrete can be reduced in half. A 4000psi mix can become a 2000psi mix at the surface with no curing.
