The 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 document was 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 included. “Compliance details throughout ACI 301-20 have been updated to align with ACI 318-19, Building Code Requirements for Structural Concrete—providing clarity on the information engineers must provide in the construction documents,” according to an ACI news release.
“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,” the release says.
