The American Concrete (ACI) Institute has announced that their new specification, ACI 301-16 Specifications for Structural Concrete, is available. In addition to this new specification, ACI also announced the latest Field Reference Manual.
ACI 301-16 has multiple sections which cover such topics as materials and proportioning of concrete, finishing of formed and unformed surfaces, and treatment of joints. The ACI committee chair notes that:
"There are several major updates to the 2016 document from previous version published in 2010, including more contractor-friendly language, removal of default requirements for slump, and provisions on alkali-silica reactivity," states Michelle Wilson, Chair, ACI Committee 301, Specifications for Structural Concrete. "The specifications have been made clearer for the user by removing wording that is confusing or subject to interpretation."
