After the concrete floor is paved, the maintenance should be started immediately. It is more suitable to spray curing agent on various concrete floors laid by machinery, and it needs to be cured by moisturizing and covering. In rainy days or when there is sufficient water for maintenance, wet maintenance methods such as covering with moisturizing film, geotextile, sacks, straw bags and straw curtains can also be adopted. It is not appropriate to use the method of water conservation.

The maintenance of cement floor should be covered with moisturizing film, felt, geotextile, sack, straw bag and straw curtain. And it is necessary to sprinkle water in time to keep the concrete surface moist all the time, and it is also necessary to determine the number of times of sprinkling water every day. In the area where the temperature difference between day and night is more than 65438 00 degrees, or the construction ground where the daily average temperature is not more than 5 degrees, thermal insulation and moisture preservation measures should be taken.

The maintenance of cement floor should be based on the increase of compressive strength of concrete floor, and its compressive strength should not be less than 80%, especially the maintenance in the first seven days. Generally speaking, the curing days are 14-2 1 day, the high temperature weather should not be less than 14 days and the low humidity weather should not be less than 2 1 day. Special attention should be paid to the concrete floor mixed with fly ash. The shortest curing time should be no less than 28 days, and it needs to be extended appropriately at low temperature.
