A fast setting concrete mix, such as QUIKRETE Fast Setting Concrete Mix #100450, is best to use in cold weather. For the purposes of concreting, cold weather may be considered to be weather that is below 50 dF during the day, or near freezing (32 dF) at night. It is important to take certain precautions in the cold weather: 1) Mix the concrete with water before placing the material in the hole, 2) store the bagged concrete in a warm environment before use, and use warm water to mix, 3) protect the concrete from freezing for at least 48 hours for a fast setting concrete, using plastic sheeting, insulated blankets, or other means. If these preventive measures cannot be taken, it would be best to wait for warmer weather.
