Headquartered in Farmington Hills, MI, the American Concrete Institute (ACI, www.concrete.org) provides numerous, valuable resources on cold weather concrete practices, including 306.1-90: Standard Specification for Cold Weather Concreting (Reapproved 2002). Authored by ACI Committee 306 – Cold Weather Concreting, 306.1-90: Standard Specification for Cold Weather Concreting (Reapproved 2002) specifies requirements for cold weather concrete practices, such as cold weather requirements for preparations prior to placement of concrete, and protection of concrete.

MasterFormat is the specifications-writing standard for most commercial building design and construction projects in North America. SectionFormat provides a uniform standard for arranging specification text in a project manual’s sections using a three-part format, General, Materials, and Execution. 306.1-90: Standard Specification for Cold Weather Concreting (Reapproved 2002) includes the following three parts and articles within each part for cold weather concrete — concrete properties and the construction operations of mixing, transporting, and placing of the concrete materials in cold weather:

  1. General
    • Scope
    • Definitions
    • Reference organizations
    • Reference standards
    • Submittal of procedures
  1. Materials
    • Scheduling protection materials
    • Concrete
  1. Execution
    • Preparation before concreting
    • Concrete temperature
    • Curing of concrete
    • Protection of concrete

Keywords: accelerating admixtures; cold weather; compressive strength; construction; curing; formwork; freezing; heating; insulation; maturity; protection; temperature.
