Best Practices for Pouring Winter Concrete. Cranesville Block's Cold Weather Concreting Guidelines:

Cold Weather Concreting Guidelines

1. Use air-entrained concrete when exposure to moisture and freezing and thawing conditions are expected.
   
2. Keep surfaces in contact with concrete free of ice and snow and at a temperature above freezing prior
   to placement.
   
3. Place and maintain concrete at the recommended temperature.
   
4. Place concrete at the lowest practical slump.
   
5. Protect plastic concrete from freezing or drying.
   
6. Protect concrete from early-age freezing and thawing cycles until it has attained adequate strength.
   
7. Limit rapid temperature changes when protective measures are removed.
