How Cold Can You Pour Concrete?

When temperatures dip below 40 °f, the chemical reactions that strengthen concrete slow down and can lead to weaker concrete. If concrete curing temperatures are below freezing, the water inside the concrete can freeze and expand, resulting in cracks.

How Cold Can You Pour Concrete?

Cold weather is a fact of life in many parts of the world, and it can have a major impact on the construction industry. Concrete is a common material used in construction projects, and it can be sensitive to extreme temperatures. So, how cold can you pour concrete?

The answer depends on several factors, including the type of concrete being used, the ambient temperature, and the temperature of the concrete itself. Generally, concrete should not be poured if the temperature outside is below 40 degrees Fahrenheit. In colder temperatures, the concrete will not set properly, increasing the risk of cracks and other structural problems.

At temperatures below 40 degrees, contractors should take extra precautions to ensure the concrete sets correctly. One option is to use a concrete mix that is specifically designed for cold weather pouring. These mixes are designed to set faster than regular concrete, and provide additional strength and durability.

Another option is to enclose the area where the concrete is being poured in a temporary structure. This can help to keep the air temperature above 40 degrees, allowing the concrete to set properly. It is important to use a breathable structure, such as a plastic sheet or other covering that will allow moisture to escape while still providing protection from the cold.
