The American Concrete Institute announces the availability of the new ACI 562-16: Code Requirements for Assessment, Repair, and Rehabilitation of Existing Concrete Structures and Commentary.
Based on nearly one century of content from ACI, these new code requirements combine the Institute's historical knowledge with state-of-the-art resources on the evaluation, repair, and rehabilitation of concrete buildings. ACI 562-16 provides minimum performance requirements that address the unique nature of existing building construction, rather than specific formulas that must be followed in any situation.
"ACI's expert members have been developing technical guidance on concrete repair and rehabilitation since the 1920s when the first article on the repair of concrete structures appeared in the Institute's technical journal," stated Ron G. Burg, P.E., executive vice president, American Concrete Institute. "While industry practices and technology have certainly progressed, these new concrete repair code requirements build upon nearly 100 years of ACI's concrete repair knowledge and provide state-of-the-art, clearly defined, and uniform requirements to extend the service life of concrete structures."
The code requirements represent a major milestone in the industry—not only is it the first material-specific set of requirements for repair materials, but it also serves as ACI's first code specifically for repairing reinforced concrete. Included in the requirements are all aspects of concrete repair, from conception to completion, including the basis for compliance, evaluation and analysis, design of structural repairs, durability, and construction.
Building specifically on the 2013 edition of ACI 562, revisions to definitions in ACI 562-16 bring this document into conformance with the International Existing Buildings Code and other standards for existing structures. ACI 562-16 also includes the addition of specific criteria requirements for assessment and design of repair and rehabilitation for varying levels of damage, deterioration, or faulty construction.
