Keep concrete moist for the first 7 daysConcrete gains most of its strength during the first week. Keep the surface continuously moist by spraying with water, covering with wet burlap, or applying a curing compound. Wet-cured concrete reaches 10-15% higher final strength than air-cured concrete.

These are rough estimates based on typical conditions. Actual curing times depend on specific mix design, aggregate type, admixtures, wind exposure, and ground temperature. Always follow your concrete supplier's recommendations and local building code requirements.
