普通混凝土浇筑完毕后应当连续浇水养护7天以上，大体积混凝土浇水养护时间

Ordinary concrete should be continuously watered and cured for more than 7 days after pouring, and the watering and curing time of mass concrete should not be less than 14 days. For mass concrete, temperature measurement measures should be taken to keep track of the internal, surface, and atmospheric temperature of the concrete to ensure that the temperature difference between adjacent interfaces does not exceed 25°C.

After the pouring of ordinary concrete has been completed, it shall be watered continuously for more than 7 days, and the watering maintenance time of large-volume concrete shall not be less than 14 days. Large volume concrete should take temperature measurement measures, at any time to grasp the internal, surface and atmospheric ambient temperature of concrete, to ensure that the temperature difference of adjacent interface does not exceed 25 degrees C.

After the completion of ordinary concrete pouring, it shall be continuously watered and cured for more than 7 days, and the watering and curing time of mass concrete shall not be less than 14 days. Temperature measurement measures shall be taken for mass concrete, and the temperature inside, surface and atmospheric environment of concrete shall be mastered at any time to ensure that the temperature difference between adjacent interfaces does not exceed 25 ℃.<br>
