Curing Concrete – Normal, Hot and Cold Weather

The concrete achieves its strength through a series of chemical reactions, known as hydration, which are initiated by the addition of water to the mixture. The rate of the reactions influences the properties of the hardened concrete such as strength, permeability, durability, abrasion resistance and resistance to freezing and thawing.
