Cold Weather Concreting Acj The general requirements for producing satisfactory concrete during cold weather are discussed, and methods for satisfying these requirements are described. Your Online Construction Book Superstore Cold Weather Concreting revised in 306r-88 you with the techniques to properly manufacture, place and protect concrete in cold weather. Introduction General requirements Temperature of concrete as mixed and placed and heating of materials Preparation before concreting Protection against freezing and protection for concrete not requiring construction supports Protection for structural concrete requiring construction supports Materials and methods of protection Curing requirements and methods Acceleration of setting and strength development References.
Supplementary material on the effect of curing temperatures on concrete strength is referenced in authoritative sources. For many structural concretes, protection considerably in excess of ack required to insure freedom from damage by early freezing is required to assure safe 30r6-88 of strength. For many structural concretes, protection considerably in excess of that required to prevent damage by early freezing is needed to assure development of adequate strength.
The general requirements for producing satisfactory concrete during cold weather are discussed, as are methods for achieving these requirements.
