Book Synopsis Corrosion Effects of Cement Stabilized Backfill on Galvanized Steel Earth Reinforcements by : Derek V. Morris
Download or read book Corrosion Effects of Cement Stabilized Backfill on Galvanized Steel Earth Reinforcements written by Derek V. Morris and published by . This book was released on 1994 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cement stabilization of backfill has been used for some time in mechanically stabilized earth type retaining walls. However, there has been no data on the corrosion life of galvanized steel reinforcement in this environment, which is intermediate in pH between normal soil and pure cement. Field observations had indicated a potential corrosion problem at a particular site in District 12. As a result of the test program conducted during this project, the following conclusions were made. First, cement addition to backfill in the usual quantities (i.e. 7% or more) raised the pH environment to values close to that of normal concrete. At these levels corrosion rates of zinc coatings were not significantly accelerated -- if anything, corrosion rates were less than for unstabilized fill. Second, very small amounts of cement addition, of the order of 1% to 4% producing pH values significantly less than 12, could cause limited acceleration of corrosion. It is, therefore, advisable to control minimum cement levels and to encourage efficient mixing. Third, elevated corrosion rates were associated primarily with the presence of inorganic ions, both for stabilized and unstabilized fill. In the case of the problem site in District 12, this appeared to be the result primarily of unusually high sulfate content in the fill. Fourth, the use of crushed concrete as backfill did not accelerate corrosion. This material, therefore, appears to be acceptable for this application.

Subcommittee on Rural Development, Entrepreneurship, and Trade and published by . This book was released on 2010 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The subcommittee has called this hearing so that members might learn more about coal ash, the small businesses that turn coal ash into useful products and the concerns that these businesses have about the proposed Federal regulations that they believe may have a negative effect on their industry ... The EPA has recently issued two proposals for regulating coal ash. One would regulate coal ash as a solid waste and would provide very limited Federal enforceability and may not provide adequate protection of the environment and human health. The other would list coal ash as a special waste under the Hazardous Waste Subtitle in the Resource Conservation and Recovery Act, Subtitle C. The second option is one that we will focus on ... since it has generated great concerns among small businesses across this country. These businesses, many of which are represented here today, have reason to believe that regulating coal ash under Subtitle C, even as a special waste, will open recycling operations to added litigation and a stigma that will discourage the ... use of the products made with recycled coal ash."--P. 1-2.

Book Synopsis Electrochemical Test Methods to Evaluate the Corrosion Potential of Earthen Materials by : Kenneth L. Fishman
Download or read book Electrochemical Test Methods to Evaluate the Corrosion Potential of Earthen Materials written by Kenneth L. Fishman and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrochemical properties of earthen materials such as electrical resistivity, pH, salt concentrations, and organic contents are commonly used to characterize the corrosion potential of buried metal elements that are in direct contact with the surrounding soil. The TRB National Cooperative Highway Research Program's NCHRP Research Report 958: Improved Test Methods and Practices for Characterizing Steel Corrosion Potential of Earthen Materials proposes a protocol describing best practices for sampling, testing, and characterizing the steel corrosion potential of earthen materials. The protocol incorporates alternatives to the current AASHTO test standards for measuring electrochemical properties.

Available in PDF, EPUB and Kindle. Book excerpt: More than ten years have passed since the first edition was published. During that period there have been a substantial number of changes in geotechnical engineering, especially in the applications of foundation engineering. As the world population increases, more land is needed and many soil deposits previously deemed unsuitable for residential housing or other construction projects are now being used. Such areas include problematic soil regions, mining subsidence areas, and sanitary landfills. To overcome the problems associated with these natural or man-made soil deposits, new and improved methods of analysis, design, and implementation are needed in foundation construction. As society develops and living standards rise, tall buildings, transportation facilities, and industrial complexes are increasingly being built. Because of the heavy design loads and the complicated environments, the traditional design concepts, construction materials, methods, and equipment also need improvement. Further, recent energy and material shortages have caused additional burdens on the engineering profession and brought about the need to seek alternative or cost-saving methods for foundation design and construction.

Available in PDF, EPUB and Kindle. Book excerpt: The Minefill series of symposia offers an international forum for exchanging ideas; presenting new technologies; and reviewing advancements in preparing, placing, and using mine backfills. The papers in this volume highlight recent advances in the industry, including a number of new paste-plant start-ups and increased industry knowledge of backfill behavior. Case histories are presented to illustrate the practical application of new technlogies. Because treatment of mine wastes is an increasingly important and visible aspect of mining, the information shared at this symposium and in this volume is crucial to success in the industry.
