Curing is a very important step in concrete construction. When concrete has been cured properly, it greatly increases its strength and durability. Through the result of hydration, concrete hardens. It is the chemical reaction between cement and water. Hydration occurs only if water is available and if the concrete’s temperature stays within a suitable range. During the curing period which is from five to seven days after the placement for conventional concrete, the concrete surface needs to be kept moist to allow the hydration process. The new concrete can be wet with soaking hoses, sprinklers or covered with wet burlap, or can be coated with commercially available curing compounds, which seal in moisture.
