ACI 308.1-11 Specification for Curing Concrete. 1 .3—DefinItions accepted—determined to he satisfactory by Architectl Engineer. cold %eather—a period when the average daily ambient temperature is below 4OF for more than three successive days. (Note: The average daily temperature is the average of the highest and lowest temperature during the period from midnight to midnight. When temperatures above 50°F occur dunng more than half of any 24-hour duration, the period shall no longer be regarded as cold weather.) Contract Documents —a set of documents supplied by Owner to Contractor as the basis for construction. These documents contain contract forms. contract conditions. specifications. drawings, addenda, and contract changes. curing period—time during which continuous curing procedures are employed.
