This guideline provides information on the properties and characteristics of grout materials for selection of a proper grout material to control water leakage through cracks and other discontinuities in concrete structures. It is also for the selection of grout materials for crack injection to control leaks through cracks in concrete structures. (formerly no. 03738).
This guideline is intended to provide information on electrochemical techniques used to mitigate the corrosion of steel in atmospherically exposed concrete structures. The information presented is based on testing and the experience of owners, engineers, contractors, and suppliers. This guideline includes information on impressed current and galvanic cathodic protection, electrochemical chloride extraction, and realkalization.

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 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 guideline is intended to provide an introduction to hydrodemolition for concrete removal and surface preparation, the benefits and limitations of using hydrodemolition, and an understanding of other aspects to be addressed when incorporating hydrodemolition into a repair project. The guideline provides a description of the equipment, applications, safety procedures, and methods of water control and cleanup.
THE RIGHT TOOL AND EQUIPMENT FOR THE JOB. The intent of this document is not to advocate one type of tool or piece of equipment versus another, or discuss tool/equipment efficiency and other properties, but simply to provide a single-source common guide that can be used in the trade when describing and specifying concrete repair tools and equipment. Specifying tools and equipment for mixing and placing concrete repair materials is extremely difficult because the industry uses multiple names for the same tools/equipment and the same names for different tools/equipment. The Problem: Different types of tools and equipment can produce different consistencies and properties in concrete repair products. The Solution: ICRI Technical Guideline 320.5R-2014 will help ensure that the appropriate tools and equipment are properly described and specified.
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.
