Provides information and guidance for the selection, evaluation, and use of surface applied corrosion inhibitors (SACI) for corrosion mitigation and supplement sound judgement by engineers, consultants, or others specializing in the repair of reinforced concrete structures experiencing corrosion induced damage. Understanding the existing concrete conditions and corrosion levels in the structure, the function and limitations of SACI materials, requirements for proper application and quality assurance/control during application, and evaluation and monitoring the performance are addressed.
Outlines the steps in preparing concrete for replacement material in areas where corroded reinforcing steel has caused cracking, spalling, delamination, or other types of deterioration. Topics covered include exposing and undercutting reinforcing steel, edge and surface conditioning, repair of reinforcing steel, and removal geometry.
This bundle includes the 110.1 (2016), 110.2 (2020), 330.2 (2016) Guide Specifications. The documents cover Guide Specifications for Structural Concrete Repair, Epoxy Injection, and Externally Bonded FRP Fabric Systems for Strengthening Concrete Structures, respectively.
This updated and revised guideline will assist contractors, NDE service providers, owners, design professionals, and material suppliers in the selection of nondestructive evaluation (NDE) methods for evaluating the condition of concrete structures. NDE methods can be very useful to perform a condition assessment prior to repairs and to provide quality control and assurance of repairs and long-term performance monitoring. Considerations in planning and executing an NDE program, including correlating with destructive methods, are discussed in the guideline. Guidance, including a brief synopsis of each method, is presented for selecting which NDE methods are appropriate for the concrete property/condition being assessed.
This special publication is a compilation of existing articles on various structural strengthening, stiffening, and stabilization topics, including external bonded reinforcement, external post-tensioning, internal post-tensioning, section enlargement and overlays, supplemental framing and span shortening, and strengthening and stabilization of masonry structures. The purpose is to provide engineers and contractors with a single-source overview of the various materials and techniques available to solve strengthening, stiffening, and stabilization problems. The wealth of information provided should provide invaluable “food for thought” to facilitate the strengthening, stiffening, and stabilization design process.
This guide is intended to provide an introduction to the techniques and procedures used to evaluate and repair existing concrete structures post-tensioned with unbonded single-strand tendons. This guide demonstrates how the strength and serviceability of a structure that has experienced deterioration can be evaluated and restored to its original—or greater—strength and serviceability. Post-tensioning design, evaluation, and repair requires specialized knowledge. There is no substitute for experience and knowledge in working with post-tensioned structures. An experienced contractor and licensed design professional team is essential when working with post-tensioned structures. [Replaces 210.2–2002 (Evaluation) AND 320.4–2006 (Repair)]
This guide specification aids the Design Professional in the preparation of technical specifications for inclusion directly into a project manual for the construction of cementitious bonded overlays that are in line with the state-of-the-art materials and methods used in the concrete repair industry. The document provides an outline for developing the three parts of the specification through suggested text, references, and commentary for evaluating alternatives. This specification section must be used with ICRI 110.1, Guide Specifications for Structural Concrete Repairs. Both the printed and PDF copies include a Word document with hidden text for easy modification of text to meet specific cementitious bonded overlay project requirements. PDF version is free to ICRI members when ordered online.
ACI and ICRI have published an updated “Guide to the Code for Assessment, Repair, and Rehabilitation of Existing Concrete Structures, A Companion to ACI 562-19.” This guide provides the licensed design professional with the knowledge, skill, and judgment to interpret and properly use ACI 562-19, and provides insight into the use and benefits of the code for contractors, material manufacturers, building owners, and building officials.
This is a reference specification that the architect/engineer 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/engineer in supplementing the provisions of this specification, as required or needed, by designating or specifying individual project requirements. The first section covers general construction requirements for all repair work. The second section covers shoring and bracing of the structure or member to be repaired, and addresses sequencing of repair work as the structure is unloaded and reloaded. The third section covers concrete removal and preparation of the concrete substrate for repair, and defines common equipment and methods. The next five sections cover materials and proportioning of concrete; proprietary cementitious and polymer repair materials; reinforcement; production, placing...

Short Description:
This guideline can be used to educate supervisors, craft workers, owners, and engineers in safe work practices for the concrete repair industry. The guideline will have universal appeal, as it has been developed to be a visual tool that depicts the safe performance of specific tasks and the hazards associated with those tasks. The requirements described are based on the most recent OSHA standards and are intended to provide guidance and training in the planning and execution of repair and restoration projects.
