The American Concrete Institute (ACI) has announced its specification, ACI SPEC-563-25: Repair of Concrete in Buildings, is now available in the International System of Units (SI). This milestone provides design and construction professionals worldwide with greater accessibility and usability of ACI’s widely respected repair specifications. The SI edition of ACI SPEC-563-25 ensures that engineers, contractors, and owners working in global markets can implement the specification seamlessly within their projects while maintaining consistency with international measurement standards.
“ACI’s mission is to develop and disseminate consensus-based knowledge on concrete and its uses,” said Mike Tholen, ACI senior managing director, technical operations. “Making our repair specifications available in SI units demonstrates our continued commitment to supporting a global community of concrete professionals as ACI expands in international markets.”
ACI SPEC-563-25 provides standardized specification requirements for the repair of concrete in buildings, covering materials, evaluation, surface preparation, application, curing, and quality assurance. Now, with SI units integrated throughout, international practitioners can more easily adopt and apply the guidance to improve durability, performance, and sustainability in concrete repair projects.
The release of the SI version of ACI SPEC-563-25 aligns with ACI’s ongoing initiative to expand access to its technical documents and standards to meet the needs of ACI’s more than 35,000 members in more than 120 countries.
ACI SPEC-563-25 in both U.S. customary Inch-Pound Units and SI units is available for purchase through the ACI Store at concrete.org. ACI SPEC-563-25 is also available in the ACI 562 PLUS Concrete Repair Subscription.
