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.
La preparación correcta de la superficie es un elemento clave para determinar el éxito de un proyecto de restaura-ción de concreto. La preparación inadecuada de la super-ficie puede llevar a la falla del sistema de protección o material de reparación, que resulta en mayores repara-ciones, gastos agregados y pérdida de uso, y puede en último término comprometer la integridad de la estructura. La preparación de la superficie es el proceso por el cual una superficie sana, limpia y adecuadamente raspada se produce sobre un sustrato de concreto. La preparación de la superficie incluye la remoción de lechada, suciedad, aceite, capas, pintura, recubrimientos, concreto sano o en mal estado y otros materiales que interferirán con la ad hesión o penetración de un sellador, recubrimiento, revestimiento de polímeros o material de reparación.
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.
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.
This is the initial document in a series of guide specifications to be prepared by ICRI. The guide specification offers a methodology for standardizing the essential requirements for structural concrete repairs by providing specification text, optional requirements, and commentary to allow the user to tailor the document to a specific concrete 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.
The purpose of this document, updated in 2023, is to provide a standardized protocol for testing and reporting of data for inorganic repair materials. Descriptions of material limitations, packaging, storage, label contents, application instructions, material composition, and material properties can be inconsistent, confusing, missing, or misleading. The ACI 364.3R/ICRI 320.3R Cementitious Repair Material Data Sheet—Guide is a first in the industry to provide this information in a standardized, logical, and consistent format so that repair materials can be appropriately selected and specified.
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.
This guideline describes the tools, techniques, and processes that are used in the evaluation of masonry façade structures. It offers background into the history and evolution of masonry structure design and construction.
A tool to help designers, specifiers, contractors, and manufacturers make the best possible decisions in selecting materials for the repair of concrete surfaces. It fully describes a process used to develop sound selection criteria that will ensure that, for each project, the material properties needed to produce durable repairs are specified.
