Guide to Cold Weather Concreting
Organization:
ACI - American Concrete Institute
Year: 2010
Abstract: INTRODUCTION
Cold weather exists when the air temperature has fallen to, or is expected to fall below 40°F (4°C) during the protection period. The protection period is defined as the time required to prevent concrete from being affected by exposure to cold weather. Concrete placed during cold weather will develop sufficient strength and durability to satisfy the intended service requirements when it is properly produced, placed, and protected. The necessary degree of protection increases as the ambient temperature decreases.
If requirements for cold weather concreting are needed in specification form, reference ACI 306.1. If necessary, add appropriate modifications to the contract documents after consulting the specification checklist.
This guide provides the necessary information for the contractor to select the best methods to satisfy the minimum cold weather concreting requirements.
