Construction Conditions
Base surface requirements: The concrete base surface should be cleaned, repaired flat, and polished to a certain roughness. Ensure that the concrete curing is completed, the strength reaches C25 or above, and the moisture content is less than 8%. After processing the base surface, the next process should be carried out as soon as possible.
Environmental temperature and humidity requirements: The construction environment temperature should be between 5–35 ℃, and the base surface temperature should be at least 5 ℃ higher than the air dew point temperature. The humidity range should be between 30% and 80%.
Ventilation conditions: Ventilation should be maintained during construction, but construction should not be carried out when there is strong wind.
Environmental temperature and humidity requirements: The construction environment temperature should be between 5–35 ℃, and the base surface temperature should be at least 5 ℃ higher than the air dew point temperature. The humidity range should be between 30% and 80%.
