Especificar el equipo adecuado para la mezcla, aplicación y acabado de materiales de reparación de concreto es extremadamente difícil, puesto que la industria utiliza varios nombres para el mismo equipo y los mismos nombres para diferentes equipos. Muchos tipos diferentes de paletas mezcladoras y mezcladoras pueden producir diferentes consistencias y propiedades en los productos de reparación de concreto. Especificar los tipos de mezcladoras mecánicas adecuados también es difícil, pues el término “mezclador de mortero” tiene muchos significados diferentes. La intención de este documento no es defender un tipo de equipo de mezclado, aplicación o acabado en comparación con otro ni discutir la eficiencia relativa u otras propiedades, sino simplemente proporcionar una sola fuente de referencia común que puede utilizarse en el oficio al describir o especificar el equipo de mezclado, aplicación o acabado para concreto.
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)]
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).
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 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 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.
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.
Provides information and guidance for the selection, evaluation, and use of surface applied corrosion inhibitors (SACI) for corrosion mitigation and supplement sound judgement by engineers, consultants, or others specializing in the repair of reinforced concrete structures experiencing corrosion induced damage. Understanding the existing concrete conditions and corrosion levels in the structure, the function and limitations of SACI materials, requirements for proper application and quality assurance/control during application, and evaluation and monitoring the performance are addressed.
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 provides information for the selection and application of materials for fluid-applied waterproofing systems to concrete pedestrian and vehicular traffic surfaces. Properly selected and applied traffic membrane systems can protect concrete from deterioration caused by abrasion, moisture intrusion, environmental forces, and chemical attack. The guideline includes system design, material properties and types, project implementation, system installation, and health and safety.
