American Concrete Institute Announces New Concrete Repair Specifications

Farmington Hills, Michigan (November 14, 2018)—The American Concrete Institute (ACI) has announced the availability of important new specifications for concrete industry professionals—ACI 563-18: Specifications for Repair of Concrete in Buildings—which can apply to any construction repair and rehabilitation project involving structural concrete by citing it in the project specifications. Mandatory requirements and optional requirements checklists are provided to assist the architect and/or engineer in supplementing the provisions of this specification by designating or specifying individual project requirements.

The document covers general construction requirements for all repair work; shoring and bracing of the structure or member to be repaired; concrete removal and preparation of the concrete substrate for repair, including equipment and methods; materials and proportioning of concrete; proprietary cementitious and polymer repair materials; reinforcement; production, placing, finishing and curing of repair materials; formwork performance criteria and construction; treatment of joints; embedded items; repair of surface defects; mockups; finishing of formed and unformed surfaces; provisions governing testing, evaluation, and acceptance of repair materials.

Sections 9 and 10 incorporate by reference two other specifications—ACI 503.7 and ACI 506.2—into this ACI standard to cover crack repair by epoxy injection and shotcrete, respectively.

ACI 563-18 complements ACI 562 code requirements for assessment, repair and rehabilitation of existing concrete structures. The ACI 562 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 provides minimum performance requirements that address the unique nature of existing building construction.

ACI will host a webinar through ACI University on specifications for repair of concrete in buildings on December 4, 2018. Details at ACIUniversity.com.
