Curing Concrete in Cold Weather

The traditional, tried-and-true method for curing concrete in cold weather is to cover it with blankets. This method is successful even if the air temperature falls below 20°F. Between the ground temperature, the heat generated by the concrete, and the insulation of the blankets, it's enough to protect the concrete as it cures.
