The American Concrete Institute has released its 2021 ACI Collection of Concrete Codes, Specifications and Practices, a collection that it deems “the most comprehensive and largest single source of information on concrete design, construction, materials, and repair.”

The collection includes nearly 50 codes and specifications along with more than 200 practices, which includes guides and reports.

Categories in the ACI Collection include concrete materials, properties, design, construction, reinforcement, specialized application, repair, structural analysis, and innovation, plus popular topics such as slabs, formwork and masonry. It features:

• ACI 318 “Building Code Requirements for Structural Concrete”;
• ACI 301 “Specifications for Structural Concrete”; and
• ACI 562 “Code Requirements for Assessment, Repair, and Rehabilitation of Existing Concrete Structures and Commentary,” among others.

According to ACI, the collection is available as an online subscription, a USB drive and a nine-volume set of books. Additionally, the online subscription includes access to current and historical versions of ACI’s codes and specifications, along with versions in both inch-pound and S.I. units. Online access for multiple users and companies is also available.
