306R-16: Guide to Cold Weather Concreting

The conditions of cold weather concreting exist when the air temperature has fallen to, or is expected to fall below, 40°F (4°C) during the protection period. The protection period is defined as the amount of time recommended to prevent concrete from being adversely affected by exposure to cold weather Cold Weather Concreting- Concreting in Cold Weather | Cold Weather Concreting. During Cold weather concreting, the rate of hardening and setting of concrete is very much retarded when the temperature falls below 21 deg. C. (70 deg. F.). At about 10 deg. C. (50 deg. F.) the action of setting slows down to about one-half of what it is at 21 deg. C.
