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.

Short Description:
This guideline can be used to educate supervisors, craft workers, owners, and engineers in safe work practices for the concrete repair industry. The guideline will have universal appeal, as it has been developed to be a visual tool that depicts the safe performance of specific tasks and the hazards associated with those tasks. The requirements described are based on the most recent OSHA standards and are intended to provide guidance and training in the planning and execution of repair and restoration projects.
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.
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.
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).
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.
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 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.
