This book presents a number of innovative uses of fly ash. Fly ash is a fine powder that is a byproduct of burning pulverized coal in thermal power plants. It is a pozzolan – a substance containing aluminous and siliceous material that when mixed with lime and water forms a compound similar to Portland cement. Though fly ash was a problem in terms of its disposal, it now has a variety of uses, such as a prime material in blocks, bricks, and PCC paving, and further applications are being investigated. As such, the recovery and reuse of fly ash wastes plays an important role in the implementation of the circular economy concept. Featuring selected, high-quality research papers presented at IconSWM 2018, the book provides valuable insights for the recycling industries, power plants, researchers, and governments.

The drive to develop more sustainable materials has made fly ash a valuable raw material in many different applications. Comprehensive and authoritative, Handbook of Fly Ash highlights the latest research efforts to develop the properties of fly ash to maximum utility while safeguarding the environment. This book takes an interdisciplinary approach to the research into the classification and compositions of various types of fly ash, such as bottom ash and boiler slag, special classes of fly ash, and their sources around the globe. This is followed by a discussion of fly ash-reinforced composites, such as elastomer-based composites and metal matrix composites. This book also covers a wide range of applications of fly ash in cement, concrete, bricks and blocks, road construction, wastewater treatment, and scrubber sludge solidification. - Highlights the recent developments in the utilization of fly ash including its preparation, functionalization, properties, and handling. - Places a focus on a wide variety of fly ash applications including recent innovations, such as alkali-activated binder, polypropylene composite, and geopolymer concrete. - Includes comprehensive coverage of the characteristics of fly ash with a particular focus on health hazards if it is not properly disposed. - Discusses fly ash-reinforced composites, such as polymer/elastomer-based composites and metal matrix composites.

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.

Phytomanagement of Fly Ash brings together the recent and established knowledge of different aspects of fly ash management, providing a cutting-edge synthesis of scientific and experiential knowledge on contaminated site restoration. Phytomanagement of Fly Ash provides readers with ecologically friendly and cost-effective solutions to decontaminate fly ash polluted sites, along with potential opportunities in phytoremediation that also yield biodiesel, aromatic oil, bio-fortified products and pulp-paper biomass. The book also focuses on novel topics, such as afforestation on fly ash catena, adaptive management, potential sink for carbon sequestration, and ecosystem goods and services. This book is a useful reference for environmental professionals in the coal industry, ecological planners and managers, students, practitioners and policymakers involved in phytoremediation. - Provides a holistic approach to fly ash, covering the ecological, economic and social issues related to its management - Addresses the multiple industrial uses of fly ash - Includes strategies to mitigate costs related to fly ash dump restoration

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.

"TRB's National Cooperative Highway Research Program (NCHRP) 749: Methods for Evaluating Fly Ash for Use in Highway Concrete presents suggested changes to coal fly ash specifications and test protocols contained in American Association of State Highway and Transportation Officials (AASHTO) Standard Specifications for Transportation Materials and Methods of Sampling and Testing (AASHTO M 295). The changes suggested include modifications to the test methods currently specified for evaluating acceptability of fly ash for use in highway concrete as well as the introduction of new test methods for enhancing such evaluations. Attachment C: Details of the Research into Methods for Evaluating Fly Ash Use in Highway Concrete is only available online."--Publisher description.
