Definition of Curing Concrete

Hydration

• Curing is the process that cement undergoes as it sets and hardens. Hydration refers to the chemical reaction that begins once water is combined with Portland cement. This bonding reaction keeps occurring as long as water is present in the concrete. The curing process relies on the maintenance of the hydration reaction.

Crystals

• Concrete forms crystals that bind the sand and gravel together after it is poured. The curing process ensures the full formation of these crystals and therefore, the achievement of the concrete's full strength.

Temperature

• The curing process regulates the temperature of the concrete during the formation of the strengthening crystals. Under high heat, the crystal formation goes too fast and causes the concrete to crack. Under low heat, the crystal formation goes too slow and the crystals do not form properly.
