The use of recycled metallic abrasives (e.g., steel grit) is becoming more common on U.S. Army Corps of Engineers (COE) projects for preparation of steel surfaces prior to application of thermal-sprayed metallic and liquid-applied coatings. The angularity of the resulting surface roughness is critical to the adhesion of the thermal-sprayed coatings, and enhances the adhesion of liquid-applied coatings. There are no established field methods that a COE inspector can use to evaluate the angularity of the abrasive or the angularity of the surface after abrasive blast cleaning has been performed. The objectives of this research were to determine the effect that the recycling of metallic abrasive has on the adhesion thermal-spray (zinc/aluminum 85/15) and liquid-applied epoxy zinc-rich coatings, and to recommend an approach that can be used to generate industry standards for recycled abrasive. The data may also be helpful in developing field inspection methods for surface and abrasive angularity that can be used to verify proper surface preparation.

Abrasive blasting of tanks and other enclosed spaces on-board ships comprises a large part of the work effort and budget allocated to surface preparation and coating for both new construction and repair contracts. Traditionally, disposable abrasives such as copper and coal slag have been used for tank blasting. The use of recoverable steel grit for tank blasting would appear to reduce or eliminate many of the problems associated with slag and mineral abrasives. Due to the durability and toughness of steel, steel grit can be reused many hundreds of times. Significantly smaller volumes of abrasive waste are generated for disposal. The durability of steel grit also results in very low dust generation, since the particles do not readily break down into fines. The recovery of steel abrasive through a vacuum recovery system greatly decreases environmental hazards by trapping paint chips and dust, which are segregated from the reusable abrasive. The higher density of steel grit in comparison to other abrasives produces increased cutting ability, while improving worker visibility through decreased dust generation. The increased cutting and low dust equate to increased productivity. Finally, the use of steel grit would not trigger the costly sampling and testing requirements of MILA- 22262A, since steel abrasive is not covered under this specification.

Choosing the most suitable coatings for structures such as bridges and building supports can extend the service life of that structure significantly. Corrosion Control Through Organic Coatings discusses the most important variables in the testing, selection, and application of heavy-duty, organic corrosion-protection paints. The book addresses the maintenance and restoration of older infrastructure and industrial plant as well as coatings for new structures made from various types of steel. The author, Amy Forsgren, examines the mechanisms of aging and deterioration caused by ultraviolet light, condensation, temperature, and chemical reactions. She also provides a complete description of composition of anti-corrosive organic coatings, including pigments, binders, and additives. Ms. Forsgren suggests which corrosion tests provide the most useful information on coating performance and corrosion-protection. Several chapters review the advantages and disadvantages of of different surface preparation methods. In addition, the author considers the environmental impact of various coatings and recognizes health hazards posed by volatile organic compounds (VOC's), toxic or hazardous pigments such as lead, and silica dust exposure. She also offers recommendations for providing safe working environments for personnel handling surface preparation. Integrating engineering aspects and corrosion expertise with paint formulation knowledge and surface chemistry, Corrosion Control Through Organic Coatings provides unique coverage of the most advanced treatments for extending the life span of heavy-duty metal structures today.

This synthesis will be of interest to bridge painting contractors, bridge maintenance and construction engineers, environmental engineers, equipment manufacturers and suppliers, and others interested in bridge paint removal. Information is provided on current practices in bridge paint removal, containment, and disposal, with special attention paid to environmental, health, and cost issues, along with a discussion of current environmental regulations governing paint removal practices. The removal of bridge paint is a nationwide problem with sensitive environmental concerns and rapid changes in available technology and regulatory oversight. This report of the Transportation Research Board describes the current state of the practice for bridge paint removal, containment, and disposal, especially with regard to lead-based or other toxic paints. Additionally, current environmental regulations and health concerns in this area are examined.
