The weather temperature is 0 degrees Celsius, can the house still lay the foundation?

The weather temperature is 0 degrees Celsius, and the house can't hit the foundation. If the concrete is attacked by negative temperature during the setting process, the hydration of cement will be hindered, and the free water in it will start to freeze. If the volume increases by 9%, the concrete will freeze, which will seriously affect the quality of concrete. Although the strength of concrete can still be improved by curing at room temperature after initial freezing, it cannot be restored to the unfrozen level, and the earlier it is frozen, the more difficult it is to restore the later strength.

When the average temperature for five consecutive days is lower than 5 degrees Celsius or the daily minimum temperature is lower than 3 degrees Celsius, winter construction measures should be taken to ensure the project quality. Because winter construction needs heat preservation and more heat energy to increase the project cost, we should try to avoid site leveling, foundation treatment, waterproof outdoor decorative roof, high-altitude pouring concrete and other projects.
