1, yes, although it is MINUS two degrees, the temperature is not particularly low, which does not have much impact on the cement floor. 2. If the temperature is lower than -5℃, this situation will bring early frost damage to the cement floor, and heat preservation measures must be taken. In addition, after pouring the cement floor, the curing temperature of the floor should be increased.
Second, how to prevent freezing when pouring concrete in winter?
1, in winter, the temperature is relatively low, so it is very important to take anti-freezing measures when pouring concrete. Antifreeze can be made by hot shed or heat storage. However, there are actually some materials coated on the concrete surface that can also play a role in heat insulation.
2, make its surface to store a certain amount of heat, but also to prevent the concrete surface from freezing, at the end of the concrete construction, be sure to cover the thermal insulation material. Don't be exposed to low temperature in winter to avoid cracking in cold winter and low temperature.
3. Once the concrete is poured, you must pay attention to maintenance in the future. If the strength of concrete is relatively low at first, the strength of concrete can be directly improved through later maintenance. The concrete is still very low, so some special cement is needed as the wall fixing material, and it can be smeared directly. Therefore, when pouring concrete in winter, it is necessary to take protective measures for the weather temperature of the construction ground, which can also play a good role in the ground.
