ACI 563-18 (SI) PDF Download

ACI 563-18 (SI) is a standard that provides specifications for the repair and rehabilitation of concrete in buildings. It is a reference specification that can be used by architects and engineers for any construction repair project involving structural concrete. The standard includes both mandatory and optional requirements checklists which can be used to supplement the provisions of the specification as needed for individual projects.

The standard is divided into several sections that cover various aspects of the repair process. The first section addresses general construction requirements for all repair work. The second section focuses on shoring and bracing of the structure or member to be repaired and provides guidance on the sequencing of repair work as the structure is unloaded and reloaded. The third section covers concrete removal and preparation of the substrate for repair, including equipment and methods.

Subsequent sections address materials and proportioning of concrete, including proprietary cementitious and polymer repair materials. The standard also covers reinforcement, production, placing, finishing, and curing of repair materials, as well as formwork performance criteria and construction. It provides guidelines for the treatment of joints, embedded items, and surface defects, and includes provisions for testing, evaluation, and acceptance of repair materials.

In addition, the standard incorporates two other specifications, ACI 503.7 and ACI 506.2, which cover crack repair by epoxy injection and shotcrete, respectively. These specifications are referenced in sections 9 and 10 of ACI 563-18 (SI) for comprehensive coverage of the repair process.
