Download or read book Environmental Degradation of Advanced and Traditional Engineering Materials written by Lloyd H. Hihara and published by CRC Press. This book was released on 2013-10-23 with total page 722 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the main, ongoing challenges for any engineering enterprise is that systems are built of materials subject to environmental degradation. Whether working with an airframe, integrated circuit, bridge, prosthetic device, or implantable drug-delivery system, understanding the chemical stability of materials remains a key element in determining their useful life. Environmental Degradation of Advanced and Traditional Engineering Materials is a monumental work for the field, providing comprehensive coverage of the environmental impacts on the full breadth of materials used for engineering infrastructure, buildings, machines, and components. The book discusses fundamental degradation processes and presents examples of degradation under various environmental conditions. Each chapter presents the basic properties of the class of material, followed by detailed characteristics of degradation, guidelines on how to protect against corrosion, and a description of testing procedures. A complete, self-contained industrial reference guide, this valuable resource is designed for students and professionals interested in the development of deterioration-resistant technological systems constructed with metallurgical, polymeric, ceramic, and natural materials.

Book Synopsis Revitalizing a Nation by : Clifford Winston
Download or read book Revitalizing a Nation written by Clifford Winston and published by Brookings Institution Press. This book was released on 2023-12-20 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: An efficient transportation system reduces the cost of distance by moving people and goods from their origins to their destinations as cheaply, quickly, and safely as possible. By enabling individuals and firms to be more productive, transportation provides the foundation for the development and growth of industries and an entire economy. Clifford Winston, Jia Yan, and Associates argue that competition and innovation are the key drivers of an efficient transportation system. The authors provide new evidence that transportation deregulation and privatization that spur additional competition among carriers and infrastructure providers, as well as new innovations that create autonomous transportation services, have the potential to rid the US transportation system of its major inefficiencies and revitalize the nation.
Book Synopsis Investigation of Anti-Icing Chemicals and Their Interactions with Pavement Concretes by : Jan Olek
Download or read book Investigation of Anti-Icing Chemicals and Their Interactions with Pavement Concretes written by Jan Olek and published by . This book was released on 2016-12-31 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The interactions of concrete specimens (both plain and with fly ash addition) with six different deicers was investigated by exposing them to solutions of sodium chloride (NaCl), magnesium chloride (MgCl2), calcium chloride (CaCl2), and the combinations of: sodium chloride with magnesium chloride (NaCl + MgCl2), sodium chloride with calcium chloride (NaCl + CaCl2), sodium chloride with agricultural by product - Ice Ban® (NaCl + Ice Ban®). In addition, control group of specimens was exposed to the deionized water. The exposures consisted of wet/dry (W/D) and freeze/thaw (F/T) cycles as well as a continuous storage in lime water at 23°C.The effects of various exposure conditions were evaluated based on the changes in the following: relative dynamic modulus of elasticity (RDME), ultrasonic pulse velocity (UPV), mass of specimens, length of specimens, mass of scaled material and compressive strength. In addition, absorption and chloride penetration measurements were performed for specimens exposed to various deicers at room temperature of 23°C. Finally, the qualitative visual evaluation of the appearance of the samples was also performed along with documentation of microstructural changes using the scanning electron microscopy (SEM).Among the deicer/anti-icers tested, calcium chloride and magnesium chloride solutions caused comparatively higher degree of deterioration than other solutions. Although the ultimate extent of visual degradation of the specimens exposed to both of these deicers was very comparable, the onset of the degradation process in specimens exposed to magnesium chloride was significantly delayed when compared to the onset of deterioration of specimens exposed to calcium chloride.The best performance (least amount of damage) was observed for specimens exposed to sodium chloride solutions followed by specimens exposed to the combination of sodium chloride with magnesium chloride and sodium chloride with calcium chloride.The test results indicate that F/T exposure conditions are much more severe than W/D regimes, even though the concentrations of deicers/anti-icers used for F/T cycles were about 50% lower than those used for W/D cycles. Moreover, the addition of fly ash has a positive influence on performance of the concrete regardless of the type of the exposure regime.

Book Synopsis Efficacy, Costs, and Impacts of Non-chloride Deicers by : Laura Fay
Download or read book Efficacy, Costs, and Impacts of Non-chloride Deicers written by Laura Fay and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this project was to synthesize available information on non-chloride deicers to allow for a more comprehensive understanding by winter roadway maintenance professionals and allow for easy comparisons between products and with sodium chloride (as salt brine or rock salt). This was accomplished through a literature search that summarized research on non-chloride deicing products and identified 46 non-chloride deicing products, summarized research on applications of various heated pavement technologies, and summarized research on anti-icing and anti-bonding/water-repellent surface treatments. Two surveys of state and local transportation agencies and vendors and manufacturers of non-chloride deicing products were conducted, respectively. The survey of state and local transportation agencies identified non-chloride products used. An evaluation of the Clear Roads Qualified Products List (QPL) Specification Document and other standards and testing requirements was conducted, which suggests that a wealth of data is collected and available for review of non-chloride deicing products. A deeper evaluation of BOD, COD, nitrogen, phosphorus, cyanide, toxicity, and corrosion is provided, because these are of particular interest when considering non-chloride deicers. Subsequently, we developed educational primers, or two-page fact sheets, for key categories of non-chloride deicers - acetates, formates, glycols, and ag-based that serve as high-level overviews of information on non-chloride deicers that can be used to make informed decision when comparing products to sodium chloride as rock salt or salt brine. This work found non-chloride deicers to be a viable option in winter roadway maintenance operations and many transportation agencies across the country are successfully using these products.

Book Synopsis Stormwater Infiltration by : Bruce K. Ferguson
Download or read book Stormwater Infiltration written by Bruce K. Ferguson and published by CRC Press. This book was released on 1994-09-21 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stormwater infiltration is the most complete approach to stormwater management. Only infiltration can simultaneously solve problems of water quality, flood control, streambank erosion, aquifer recharge, and maintenance of downstream base flows and wetland hydroperiods. Stormwater Infiltration is the first book to explain the principles of natural science on which infiltration is based, how to apply infiltration to any region of the country, and what kinds of results can be expected. It brings into one publication the complete range of necessary information on soils, vegetation, infiltration, hydrology, design criteria, site layout, construction process for surface and subsurface basins, porous paving materials, feasibility, maintenance, and performance. It draws more than half a century's actual experiences from all over the United States to place stormwater management in a context of environmental balance and quality for human life.
