How to use concrete antifreeze? Chuzhou antifreeze price Fengyang concrete antifreeze manufacturer

Concrete is not suitable for construction in sub-zero environments. If the project requires construction, antifreeze must be added. So how to use concrete antifreeze? Let’s find out together Let's see.

1. How to use concrete antifreeze

1. Apply an appropriate amount of antifreeze Add the agent to the concrete aggregate and mix, and the mixing time should not be less than 3 minutes. To determine the amount of antifreeze to be added, if the environment is minus 5 degrees to minus 0 degrees, only about 5% of the antifreeze needs to be mixed. When construction is carried out in an environment of minus 5 degrees to minus 10 degrees, 7% of the antifreeze needs to be added. About 9% antifreeze is required for construction in an environment of minus 10 degrees to minus 15 degrees.

2. After mixing, a test needs to be conducted to ensure that the anti-freeze is qualified, and the concrete can be poured and used directly.

2. What should you pay attention to when constructing concrete in winter?

When constructing concrete in winter, pay attention to the surrounding There are requirements for temperature. If the temperature is within 5 for more than 5 consecutive days, insulation and antifreeze measures must be considered. Antifreeze materials can be added to the concrete materials before construction, and they can also be covered with film for insulation after construction to avoid temperature rise. Too low situation.

Because if the temperature is too low, the moisture in the concrete and the moisture in the soil will easily freeze, which will affect the early strength of the concrete. At the same time, Brittle cracking may occur.

Since concrete construction in winter requires higher costs and is more difficult, it is necessary to avoid construction in winter. If it is a project that must be constructed, you can Develop corresponding measures according to site conditions, especially temperature changes must be well controlled.

For conditions below 0 degrees, antifreeze must be added to the concrete, which can effectively reduce the freezing point and not only improve the frost resistance of the concrete, but also Can improve the early strength of concrete.
