Available in PDF, EPUB and Kindle. Book excerpt: High Volume Fly Ash Concrete (HVFA) is a type of concrete that incorporates a large volume of fly ash as a partial replacement for Portland cement. Fly ash is a by-product of coal combustion that is collected from power plants, and it has pozzolanic properties that can enhance the durability, workability, and strength of concrete. In HVFA, the replacement of Portland cement with fly ash typically ranges from 50% to 70% by mass, resulting in a reduction in the amount of cement required and a decrease in the carbon footprint of the concrete. However, this high volume of fly ash can also affect the behavior of the concrete in structural design. One of the main challenges in designing with HVFA concrete is the potential for delayed strength development. Fly ash reacts slowly with water, and this can result in a longer period for the concrete to reach its desired strength. This delayed strength development must be taken into account in the design process to ensure that the concrete can support the intended loads. Additionally, the use of HVFA can also affect the workability and setting time of the concrete. The high amount of fly ash can make the mixtures more viscous and harder to place, and it can also result in longer setting times. This can impact the construction schedule and require adjustments to be made in the mix design and placement procedures. On the other hand, HVFA can also provide benefits in structural design. The lower heat of hydration and reduced shrinkage characteristics of HVFA can minimize the potential for cracking and improve the long-term durability of the concrete. Furthermore, the use of fly ash can contribute to the overall sustainability of the project by reducing the carbon footprint and diverting waste from landfills. Overall, the behavior of HVFA concrete in structural design requires careful consideration of its unique properties and potential challenges. With proper mix design and construction practices, HVFA can provide a durable and sustainable option for concrete structures.

This book was released on 2024-01-20 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: When infrastructure is built quickly, development occurs. Concrete is the go-to material for construction projects. Manufacturing cement is a significant contributor to atmospheric carbon dioxide. Using carbon-neutral materials like crimson mud or powdered snail shells can reduce cement's carbon dioxide emissions by half. As an adaptable alternative to traditional concrete, HVFA concrete has many uses. Long-lasting and useful in Plain Cement Concrete (PCC) projects, fly ash also enhances concrete's workability. The positive effects of fly ash on the environment, such as lower carbon dioxide emissions, are not new. Adding fly ash to concrete increases its strength and segregation, which reduces its price and makes it simpler to pump.

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

Book excerpt: Why a book about concrete? Because we use so much of it -- far more than any other building material. It seems only sensible to inquire as to how we can use this ubiquitous building material without undue damage to the life and landscapes that surround us. You may have heard of fly ash as an eco-friendly alternative to using portland cement in concrete, but until now there has been no easy guide to how it makes superior concrete, or to how to use it. This book isn't just for people who want to "build green" -- it's for people who want to build better concrete.

Available in PDF, EPUB and Kindle. Book excerpt: While the use of small proportion of fly ash in the binder of concrete is well understood and accepted in many countries, the technology relating to the use of high volume (40% by weight or more of binder) of fly ash in structural concrete is a more recent development. This paper discusses the development of high volume fly ash (HVFA) concrete in Australia and overseas with specific emphasis on its potential applications. Mix design method and data are described. It has been found that HVFA concrete can be designed within the constraints of the present Australian code of practice to give equivalent 28 day compressive strength to plain cement concrete. However, the volume stability and durability properties of HVFA concretes have been found to be significantly better than the equivalent plain cement concrete. With its inherent increased cohesiveness and long term properties, potential applications are identified and discussed with respect to the specific properties.
