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 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)]
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.
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 is the second document in a series of guide specifications prepared by ICRI. The guide specification addresses the requirements for the supply and installation of FRP fabric systems by providing specification text, optional requirements, references, and commentary to allow the user to tailor the document to a specific structural strengthening repair project, and use as a technical specification section in a complete project manual. Both the printed and PDF copies include a Word document with hidden text for easy modification of text to meet specific repair project requirements. Note that the design of the FRP system is outside the scope of these guide specifications.
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.
Illustrates and describes the application methods commonly used for placement of concrete repair materials, along with material requirements, the best applications, and cautions and limitations for each. In addition, engineering considerations, surface preparation, constructability, environmental factors, quality assurance/control, and safety are addressed.
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).
An aid for the selection process, this guideline describes several methods of strengthening structures including externally bonded systems, post-tensioning, section enlargement and supplemental supports (formerly no. 03742).
