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.
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:
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.
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.
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.
Familiarity with contract types, the selection of appropriate repair work items, and documentation of completed work is essential for successful completion of a concrete repair project.This guide is intended to assist owners, consultants, and contractors in defining recommended methods of quantity measurement and contract types for concrete repair work.
This guideline will assist contractors, owners, engineers, architects, and material suppliers in the selection of nondestructive evaluation (NDE) methods for evaluating the condition of concrete structures. NDE can be a very useful method 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 guide provides a recommended method of evaluating the adequacy of concrete surface preparation and tensile bond strength of cementitious and polymer concrete surface repairs using the in-situ drilled core tensile pulloff test. The guide outlines equipment and material requirements, the test procedure, reporting, and acceptance criteria. This update also includes failure modes for concrete substrate tests.
