Do you have to wet concrete while curing?

ANSWER: Keeping concrete moist helps the curing process. Concrete hardens as a result of a chemical reaction, called hydration, between cement and water, not because it dries. … Moist-curing concrete for 20 days more than doubles its strength compared to four days of moist-curing, which is considered a minimum.
