What are the rules for placing concrete in cold weather on South Carolina DOT projects?
Do not place concrete if air temp is below 35°F without RCE authorization. If placing above 35°F or with authorization, protect concrete to maintain air temp between 50°F–100°F for 96 hours post-placement. Monitor concrete temps for 4 days. Use approved measures like curing blankets (min 4 days), heating equipment, or windbreaks. Remove ice/frost from materials before placement. Alternative measures require RCE approval.
