My hometown is in rural Taixing, Jiangsu. Winter is coming, and I want to go home and build a house. I'm afraid of freezing the outer wall in cold weather. How much temperature does the outer wall not freeze? Rigid masonry ... If the temperature is above 0 degrees for 5~ 10 days after you build the wall, the wall will be fine. The higher the temperature, the less time it takes. If the temperature of the wall is below 0 degrees for several days in a row, the wall will be reversed as soon as the weather turns, that is, water seeps out of the cement, indicating that the cement has no cohesive force, so it will be demolished and rebuilt.
