Curing Concrete, Chapter 12 - The University of …
Curing is the maintenance of a satisfactory moisture con-tent and temperature in concrete for a period of time imme-diately following placing and finishing so that the desiredproperties may develop (Fig. 12-1). The need for adequatecuring of concrete cannot be overemphasized. Curing has astrong influence on the properties of hardened concrete ;proper Curing will increase durability, strength, watertight-ness, abrasion resistance, volume stability, and resistance tofreezing and thawing and deicers. Exposed slab surfacesare especially sensitive to Curing as strength developmentand freeze-thaw resistance of the top surface of a slab canbe reduced significantly when Curing is portland cement is mixed with water, a chemicalreaction called hydration takes place.
