New ACI Specifications for Concrete Construction – ACI 301-20

ACI 301-20The American Concrete Institute has released the new ACI 301-20, Specifications for Concrete Construction, along with the companion ACI Field Reference Manual.

ACI 301 is a reference specification that engineers, architects, and specifiers can apply to projects involving concrete construction. The scope of the new ACI 301-20 expands 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 throughout ACI 301-20 have 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.

Checklists and more

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

Along with the release of ACI 301, the Institute has also published a new ACI Field Reference Manual. The ACI Field Reference Manual includes the complete ACI 301-20 specifications and more than 20 selected reference documents on measuring, mixing, transporting, and placing concrete; concrete pumping methods; hot- and cold-weather concreting; consolidation; and concrete formwork – providing a convenient resource for use in field offices, jobsite trailers, and more.

ACI Specifications for Concrete Construction and the ACI Field Reference Manual are both available in printed and digital formats.

To assist users in navigating the changes to ACI 301-20, ACI University will also be releasing an on-demand course. Members of the ACI 301 committee will present this online course. It will provide insight on both the revisions and updates in this new specification.
