The organization that writes the industry standards for how concrete is designed and built.
ACI, the American Concrete Institute, is a nonprofit technical society founded in 1904 that develops and publishes standards, codes, and guides for the design, construction, and materials of concrete structures. ACI 318 (Building Code Requirements for Structural Concrete) and ACI 301 (Specifications for Structural Concrete) are among the most widely adopted concrete standards in the United States. Contractors, engineers, and inspectors reference ACI standards throughout concrete construction.
