Early cracking in slabs and other large concrete structures is often. The temperature of concrete should not be less than 5ºC when delivered. The American Concrete Institute ACI ACI 306R-10 has stated that cold weather exists when the air temperature has fallen to or is expected to fall below 40F 5C during the protection period.
What about too hot.
This is the ideal temperature for concrete to set without freezing and also for it to set to an ideal strength. At temperatures below 40 degrees Fahrenheit the initial curing process can take anywhere from two to 24 hours longer and when cold enough it can be stopped entirely. Temperatures below 50F will begin to slow the curing process and the water in the cement is at risk of freezing at temperatures below 40F. The temperature of concrete should not be less than 5ºC when delivered. Man its hot outside. How Does Concrete Cure.
