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 guideline is intended to provide information for the selection and application of materials
for fluid-applied waterproofing systems to concrete for horizontal pedestrian and vehicular
traffic surfaces.
Concrete is subject to deterioration by a variety of mechanisms. Properly selected and applied
traffic membrane systems can protect concrete from deterioration caused by abrasion, moisture
intrusion, environmental forces (freezing-and-thawing cycling), and chemical attack. This
guideline provides information on the common service conditions, basic review of the properties
of concrete, surface preparation, system designs, and materials used for traffic membranes.
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.
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.
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.
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 updated and revised guideline will assist contractors, NDE service providers, owners, design professionals, and material suppliers in the selection of nondestructive evaluation (NDE) methods for evaluating the condition of concrete structures. NDE methods can be very useful to perform a condition assessment prior to repairs and to provide quality control and assurance of repairs and long-term performance monitoring. Considerations in planning and executing an NDE program, including correlating with destructive methods, are discussed in the guideline. Guidance, including a brief synopsis of each method, is presented for selecting which NDE methods are appropriate for the concrete property/condition being assessed.
This guideline is intended to assist architects, engineers, owners and their agents, developers, general contractors, and flooring contractors who are accountable for the successful installation of a floor covering or coating over an interior concrete sub-floor that is on, below, or above grade. This guideline provides information regarding moisture issues, moisture testing methods, interpretation of test results, and moisture mitigation strategies. The information provided in the guideline is meant to assist in the successful installation of floor coverings and coatings.
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.
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.
