What is Concrete Temperature Limit?
Concrete placed & cured at a moderate temperature (15–25°C) will gain higher strength & durability than 35°C concrete. Curing concrete at high temperature accelerates curing and strength achievement, but provide lower maximum concrete strength. ACI 306 specify limits for concrete temperature in cold weather conditions.
