Normally, we need to maintain and cover the concrete within 12 hours after the cement product is poured. As for the maintenance time: for concrete mixed with portland cement, general portland cement or slag portland cement, it must not be less than 7 days, and for concrete with retardation admixture or impermeability In 14 days, the number of sprinklers should be able to keep the concrete in a wet state, and the maintenance water should be the same as the mixing water.

Points to note: If the average temperature of the day is less than 5 degrees Celsius, do not sprinkle water. Cover the concrete for maintenance with plastic cloth. The exposed surface should be tightly covered and the plastic cloth should be kept condensed.
