Is it possible to pour concrete if it freezes at night?

In order to prevent concrete from freezing at low temperatures, special antifreeze additives can be added. These additives contain chemical components that help prevent water from freezing in the concrete mix and make the concrete more resistant to low temperatures.

What should I add to the concrete so that it does not freeze?                                    

Antifreeze additives are usually introduced into the concrete mix during its preparation. They help to reduce the freezing point of water inside concrete, which allows it to maintain its strength and structure even at low temperatures. It is important to choose the right antifreeze additive, taking into account the specific climatic conditions and requirements for concrete.

Antifreeze additives can be available in various forms, such as powders or liquids, and are usually purchased from building materials suppliers. It is important to follow the manufacturer's recommendations regarding the dosage and method of application of antifreeze additives in order to achieve the best results.

In addition to antifreeze additives, it is also important to consider other factors when pouring concrete in cold conditions, such as proper insulation, temperature control and compliance with recommendations for the care of fresh concrete during solidification.

Is it possible to fill the foundation at minus 5?

Pouring the foundation at a temperature of minus 5 degrees Celsius can be risky and is not recommended without taking appropriate precautions. Low temperatures can lead to freezing of water in the concrete mixture, which can damage the structure of concrete and worsen its strength characteristics.

If pouring the foundation is necessary in the cold season, then the following measures should be taken:

• The use of antifreeze additives:

Adding antifreeze additives to the concrete mix can help prevent water from freezing inside the concrete and improve its resistance to cold.

• Concrete heating:

The use of heating systems or insulation around the shape of the foundation can help maintain an optimal temperature during pouring and initial solidification of concrete.

• Cold protection:

After pouring the foundation, it is necessary to protect it from low temperatures using insulation materials, films or other materials.

• Planning and consulting with professionals:

It is important to discuss the foundation pouring plan with engineers and concrete specialists in order to choose the best methods and materials for specific climatic conditions.

However, it is recommended to avoid pouring the foundation at extremely low temperatures, if possible, and wait for warmer conditions to ensure the safety and quality of construction.
