What are the requirements for pouring concrete in cold weather?
Pour concrete when air temp ≥40°F or if ≤40°F within 24h [1]. Preheat forms/reinforcement to ≥40°F if air temp <40°F [1]. Mix concrete at 50–80°F [1]. Heat water/aggregates if air temp ≤40°F [1]. Do not heat cement or add salt [1]. Protect concrete until it gains strength per 502.3.10 [1]. For bridge floors, avoid pouring if temps will drop below 32°F within 24h unless engineer allows [3]. Reduce enclosure temp gradually at end of protection (≤5°F/hour, ≤40°F/24h) [3].
