The American Concrete Institute has expanded the scope of ACI 301-20, Specifications for Concrete Construction, to include internal curing, mineral fillers and recycled aggregates, along with evaluation requirements for elements cast with self-consolidating mixes and structures with defined modulus of elasticity requirements. Compliance details throughout the document have been updated to align with ACI 318-19, Building Code Requirements for Structural Concrete—providing clarity on the information that design and engineering professionals must include in construction documents.
As a companion, the new ACI Field Reference Manual includes complete ACI 301-20 specifications and more than 20 selected documents on measuring, mixing, transporting, and placing concrete; pumping methods; hot- and cold-weather practice; mix consolidation; and, formwork. To assist users in navigating ACI 301 changes, ACI University will be releasing an online course, available on demand and presented by Committee 301 on Specifications for Structural Concrete members.
ACI 301-20, Specifications for Concrete Construction, and the Field Reference Manual are available in printed and digital formats through www.concrete.org/store.
