Cold Weather Concreting Guidelines

Cold weather can have some serious, and irreversible, adverse effects on concrete:

• Inadequate strength gain associated with low concrete temperature
• Delayed initial set
• Fluctuations in workability
• Concrete damage due to freezing at early ages

And cold weather for concrete is not really all that cold. Problems can occur at temperatures as warm as 50 F.

During cold weather the project team must have cold weather concreting practices in place to assure that the concrete will perform as designed.
