Book excerpt: Fly ash is a by-product of the combustion of coal and other waste materials. In recent years, there has been intensive research on fly ash because of the increasing demand for the recycling of industrial by-products to improve sustainability in manufacturing and infrastructure. This book presents some of the latest developments in the generation, characterisation, utilisation and environmental impacts of fly ash. Recent developments on the methods of collection and analysis of fly ash, and novel applications such as in geopolymers and recovery of resources from fly ash are included. The book is intended for professionals in research and academics, and students interested in materials and sustainability. The book consists of 17 chapters contributed by 42 authors. Each chapter ends with an extensive list of references for further information. The topics on fly ash have been grouped into the following three parts: Part 1: various sources, methods of collection, factors influencing collection efficiency, flow and hydrodynamic behaviours, methods of characterisation, physical, chemical, leaching and radiation properties, and extraction of metals from fly ash; Part 2: different technological initiatives on utilisation, applications in the construction industry, use as a supplementary cementitious material, alkali-activated binder, polypropylene composite materials, and behaviour of fly ash geopolymer concrete; and Part 3: health and environmental issues such as the effects on lung and heart, bioleaching for detoxification, ash from incinerated wastes, and lifecycle assessment of civil structures using fly ash.

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.
Download or read book Coal Fly Ash written by Miriam Gray and published by Nova Science Publishers. This book was released on 2018-11-27 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Due to rising energy demand, the amount of coal utilization is escalating at a fast rate, leading to a rise in ash generation. Coal Fly Ash: Properties, Applications and Performance begins by presenting a study wherein the physiochemical properties of coal ash were analysed and based on that, their potential for reuse was identified. Next, the synergy between Portland cement and coal fly ash was investigated. Raw materials were characterized in terms of chemical and mineralogical composition and physical properties. Mortars were manufactured and the effect of the addition of different ratios of coal fly ash (0-80 wt %) as a partial substitute of Portland cement was studied. Following this, an investigation was carried out to explore the behaviour of coal ash with hydrated lime as mineral filler in hot mix asphalt, in an attempt to determine a sustainable solution for the management of coal ash in Mauritius. The closing chapter describes the synthesis process used to obtain zeolite Na-A from coal fly ash via fusion with NaOH followed by hydrothermal reaction. Coal fly ash is a low cost source of both silica and alumina. The molar ratio of SiO2/Al2O3 for zeolite 4A formation was achieved through the addition of sodium aluminate solution/aluminum waste as aluminum sources"--

Download or read book Coal Combustion Products CCPs written by Tom Robl and published by Woodhead Publishing. This book was released on 2017-04-29 with total page 566 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coal Combustion Products (CCPs): Their Nature, Utilization and Beneficiation is a valuable resource for engineers and scientists from the coal, cement, concrete, and construction industries seeking an in-depth guide to the characteristics, utilization, beneficiation, and environmental impacts of coal combustion by-products. Researchers in universities working in this area will also find much to expand their knowledge. The book provides a detailed overview of the different waste materials produced during power generation from coal, exploring their nature, beneficiation techniques, applications, and environmental impacts. Strong focus is placed on coal fly ash, bottom ash, and flue gas desulfurization materials, and their employment in cement, concrete, gypsum products, aggregates, road construction, geotechnics, and agriculture, among other products and industries. Part 1 focuses on the nature of coal ashes, with chapters on their origin, generation, and storage, both in ponds and landfill. The coal combustion by-products produced as a result of clean coal technologies are the focus of the final chapter in the section. The next group of chapters in Part 2 considers the utilization of different waste materials, including the key products coal fly ash, bottom ash, and flue gas desulfurization materials. This is followed by a contribution reviewing the latest research into innovative and advanced uses for coal ash. After an introduction to ash quality problems and quality monitoring, Part 3 concentrates on the essential area of by-product beneficiation techniques, in other words how to maximize the quality of materials for the end user. Topics covered include separation methods, thermal processing, and chemical passivation. The final section of the book addresses environmental issues, including the use of coal combustion by-products in green construction materials and the essential health and safety considerations associated with their use. An essential reference on the nature, reactivity, beneficiation, potential and environmental risks of coal-combustion by-products Contains an in-depth review of the origin and geochemistry of coal ash Explores the utilization of coal combustion by-products as supplementary cementitious materials to reduce the anthropomorphic greenhouse gas emissions associated with the use of ordinary Portland cement concrete Describes the essential area of the toxicology of coal combustion by-products
Download or read book Characteristics of a Coal Fly Ash Subjected to Additional Processing written by Christopher W. Swan and published by . This book was released on 2011 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents the results of a study of the physical and environmental properties of pre- and post-processed fly ashes (termed Raw and Processed fly ashes, respectively). The ashes were collected from a coal-fired power plant in the northeastern U.S. which utilizes a carbon burn-out unit (CBO) to prepare the fly ash for concrete and other construction applications. Measured physical properties included carbon contents via loss-on-ignition (LOI), specific gravities, gradation analyses, and scanning electron microscopy (SEM). In addition, total and leachable concentrations of lead, selenium, and arsenic were determined. Leachable concentrations were determined for leaching solution pHs varying between 1.5 and 11.5. When compared to Processed fly ash, Raw fly ashes had an expectedly higher LOI (approximately 2% versus 6% carbon content, respectively) and lower specific gravity (2.37 versus 2.18, respectively). Although the total metal content of the fly ashes was similar, leachable metal concentrations were notably higher for the Processed fly ash over the full range of leaching solution pHs evaluated. The test results indicate that the CBO process, at times necessary to create usable fly ash, can result in fly ashes with notably altered physiochemical properties that lead to higher leachable contaminant concentrations.
