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.
Este lineamiento proporciona una guía sobre la remoción de concreto y los procedimientos para la preparación de la superficie paray la reparación del de concreto deteriorado provocado por la corrosión del acero de refuerzo. Se discuten la geometría de la remoción, la configuración del área de reparación, el proceso de remoción, la preparación del borde, la reparación del refuerzo, la preparación e inspección de la superficie necesarias para las reparaciones durables. Se incluyen consideraciones especiales para la remoción de concreto asociada con la reparación de columnas.
Summarizes the capabilities, operating requirements, and limitations of the various methods used to prepare concrete surfaces for the application of protective sealers, coatings, polymer overlays, and concrete repair. Benchmark profiles are included which provide visual standards for purposes of specification, application, and verification. In this updated version of the guideline you will find; surface retarders and handheld breakers have been added to the surface preparation methods; surface preparation methods have been updated; and a new appendix summarizes considerations for selecting surface preparation methods and describes various test methods used to evaluate the prepared surface. Plus, concrete surface profile (CSP) 10 has been added to reflect a more aggressive CSP used for concrete repair.
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
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. (Joint SSPC/NACE/ICRI document).
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.

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.
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.
