scope:

This document provides guidance on concrete removal, substrate and reinforcement preparation, material selection, material application methods, and protective systems for concrete structures (Fig. 1.2). An overview of concrete repair methodology is included with references to ACI 562 and ACI 563.

In addition to concrete repair, this document provides guidance for the strengthening of concrete structures. Many of the same techniques are used to both repair and strengthen concrete members and structures, including demolition, bonding new material to existing substrate, and installation of new reinforcing steel.
