The main method of curing cement mortar is natural conservation. Natural conservation refers to the measures of covering, moistening, wind blocking, heat preservation, etc., under natural conditions (greater than +5°C). The natural conservation covers water conservation and plastics. Film curing two.
Covering water conservation shall be covered with mortar, sawdust, wet sand and other suitable materials within 3 to 12 hours after the mortar is poured. Water shall be kept moist and the watering maintenance date shall not be less than 7 days and nights. The number of times of watering should be sufficient to keep the mortar moist enough. Generally, when the temperature is above 15°C, it should be watered at least once every 3 hours during the first three days and nights after the mortar is poured, and it should be watered twice at night. In the future conservation, it should be watered about 3 times every day and night. Under dry climate conditions, the number of watering should be increased appropriately. Large-scale floor can be maintained with animal water.
The plastic film is maintained by covering the plastic film, so that the mortar is isolated from the air, moisture is no longer evaporated, and the cement is cured and hardened by hydration of the mortar.
