ACI Releases New Specifications, Manual


The American Concrete Institute has released a new ACI 301-20, Specifications for Concrete Construction, as well as a companion ACI Field Reference Manual.

As a reference for projects involving concrete construction, ACI 301 has now been expanded to include shotcrete, internal curing, mineral fillers and recycled concrete aggregates. Evaluation requirements for concrete made with self-consolidating concrete and structures with defined requirements for modulus of elasticity of the concrete are also included. 

Compliance details have also been updated to align with ACI 318-19, Building Code Requirements for Structural Concrete. This provides clarity on the information engineers must provide in the construction documents, according to ACI.

In addition, two checklists for incorporating ACI 301 into concrete specifications are included. The first of these checklists indicates specific qualities, procedures and performance criteria that the specifier must include in a project specification that are not defined in ACI 301-20. The second checklist identifies choices and alternatives that the specifier can include as requirements in a specification. 

The ACI Field Reference Manual includes the ACI 301-20 specifications and more than 20 reference documents on measuring, mixing, transporting, and placing concrete; concrete pumping methods; hot- and cold-weather concreting; consolidation; and concrete formwork.

Both ACI 301 and the Field Reference Manual are available in printed and digital formats.
