Concrete can be placed safely throughout the winter months if the concrete mixture and its temperature are adapted to the construction procedure and the ambient weather conditions.
How to work with concrete in cold weather
When winter arrives, we need to take certain precautions to protect against some of the potential problems of placing concrete in cold weather-specifically, when the temperature drops below 40 degrees F (4 degrees C).
Commonsense tips for concreting in cold weather:
Concrete that has been frozen just once at an early age can be restored to nearly normal strength by providing favorable curing conditions. Such concrete, however, is not as resistant to weathering, nor is it as watertight as concrete that has not been frozen. If concrete is frozen and kept frozen at about 14 degrees F (-10 degrees C), it will gain strength slowly. Below that temperature, cement hydration or concrete strength gain ceases.
