The use of accelerators and antifreezes, keeping of temperature records, heating of materials, subgrade preparation, protective coverings, heated enclosures, curing, and form removal are discussed for several types of concrete structures and preferred methods are indicated. Supplementary material on the effect of curing temperature on concrete strength are given in an appendix. A list of selected references is included.
