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.

Short Description:
Este Lineamiento pretende ser una herramienta usada para educar a supervisores, trabajadores del oficio, propietarios e ingenieros sobre las prácticas de trabajo seguras en la industria de reparación de concreto. El lineamiento se ha desarrollado para ser una herramienta visual que representa el desempeño seguro de tareas específicas y los peligros asociados con ellas. Los requerimientos descritos aquí se basan en los estándares de OSHA más recientes y pretenden proporcionar una guía y capacitación en la planeación y ejecución de proyectos de reparación y restauración.
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 assist the contractor, licensed design professional, and owner in the development of performance specifications for quality assurance and quality control of epoxy injection of concrete cracks. It includes process-control methods to assess if satisfactory injection work is being performed. Quality assurance methods described include visual observations and testing samples during the injection work, and removing concrete core samples and performing nondestructive testing of completed repairs.
Familiarity with contract types, the selection of appropriate repair work items, and documentation of completed work is essential for successful completion of a concrete repair project.This guide is intended to assist owners, consultants, and contractors in defining recommended methods of quantity measurement and contract types for concrete repair work.
The intent of this document is to provide objective, standards-based comparison for the
specification, evaluation, and approval of the degree of surface preparation of exposed
conventional reinforcing steel by abrasive media blasting and mechanical hand tool methods.
This guide is designed for use with associated illustrative materials available in digital or
physical form through ICRI.
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.
Dans l'industrie de la construction, il est parfois difficile de spécifier les bons outils pour le mélange, l'application et la finition des matériaux de réparation. En effet, il n'est pas rare qu'un même terme désigne plusieurs outils et qu'à l'inverse, un même outil soit désigné par plusieurs termes. Or, il existe une grande variété de mélangeurs et de palettes de mélange, lesquels confèrent différentes consistances et propriétés aux matériaux de réparation. Le problème se présente aussi avec les mélangeurs mécaniques. Par exemple, le terme "malaxeur à mortier" peut être interprété de diverses manières. L'objectif de ce document n'est pas d'évaluer l'efficacité des outils offerts sur le marché, ni de favoriser l'emploi d'un outil plutôt qu'un autre; il vise simplement à offrir une référence terminologique commune et de source unique aux professionnels de la construction afin de faciliter la description ou la spécification des outils utilisés pour le mélange, l'application et la finit
This guide provides a recommended method of evaluating the adequacy of concrete surface preparation and tensile bond strength of cementitious and polymer concrete surface repairs using the in-situ drilled core tensile pulloff test. The guide outlines equipment and material requirements, the test procedure, reporting, and acceptance criteria. This update also includes failure modes for concrete substrate tests.
The information in this technical committee report deals with the design, installation, and maintenance of protective polymer flooring systems that are applied and directly bonded to concrete. Contains detailed information on the aspects of flooring technology, performance properties, surface preparation requirements, installation procedures, and testing to attain long-term service from a variety of polymer flooring systems.
