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.

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"--

Available in PDF, EPUB and Kindle. Book excerpt: The present book deals with various, very significant topics of coal fly ash beneficiation, such as treatment of acid mine drainage with coal fly ash, toxic metal adsorption using coal fly ash, recovery of metals from coal fly ash and phytoreclamation of abandoned acid mine drainage site after treatment with coal fly ash, the status of research in coal fly ash utilization and applications and some other related topics in this growing and increasingly important research area. Overall, coal fly ash beneficiation has come to assume an important role in most areas of waste management research today. Continued growth and emphasis on scientific research is expected in all areas of waste management and conversion of waste to wealth technologies.
