Concrete Curing Temperature Makes a Difference

May 22, 2017 · By the age of 28 days the high-temperature concretes were weaker than the 73°F concrete. From 28 days to 1 year the 55°F concrete was considerably stronger than the 73°F concrete. All of this suggests that, provided there is continuous curing, concrete cured at about 55°F for the first 28 days ultimately reaches the highest strength (Concrete). Hot Weather Concrete Temperature Limits

CIP 27

Low concrete temperature has a major effect on the rate of cement hydration, which results in slower setting and rate of strength gain. A good rule of thumb is that a drop in concrete temperature by 20°F [10°C] will approxi-mately double the setting time. The slower rate of set-ting and strength gain should be accounted for when

Tips for Curing Concrete in Cold Weather

Aug 23, 2019 · Concrete exposed to cold temperatures will take more time to reach an initial set, which may mean that the finishing crew needs to be present for a longer period of time. Windbreaks can help protect the concrete (and workers) from winds that can cause quick temperature drops and evaporation that is too swift.
