Concrete Curing Temperature Chart . For most concrete structures, the curing period at temperatures above 5º c (40º f) should be a minimum of 7 days or until 70% of the specified compressive or flexural strength is attained. The general guidelines suggest that the concrete curing temperature must be maintained at >5°c (40°f) for 48 hours (aci 306).

Digital vs chart recorder one of the requirements of astm c511 is that your curing facility must be monitored by a temperature recorder. The period can be reduced to 3 days if Curing measures, in general, are specified in aci 308.1.
Cold-Weather Concreting So the objective is to keep our young and impressionable concrete damp and at the right temperature (ideally between 50 and 85 f). Investigations by paul klieger reported in the portland cement association research bulletin 103 show the strength of type i portland cement concretes at various ages when cured for the first 28 days at temperatures of 120°, 105°, 90°, 73°, 55°, 40° and 25°f, and then cured for the remaining period at 73°f until an age of 365 days. In a perfect world, the temperature of fresh concrete should be above 50 °f, but cured and maintained at 50 °f. If the concrete’s temperature is too high (in cold weather, this is hard to accomplish), then crushed ice may be added to the mix.
