Available in PDF, EPUB and Kindle. Book excerpt: A best practices guide is developed from a synthesis of recent research on high-volume fly ash (HVFA) concrete mixtures. These best practices can be applied by the concrete construction industry to achieve desired properties and to ensure the (high) performance of HVFA concrete mixtures in practice. As such, the report considers all aspects of HVFA concrete production, from the characterization of the starting materials, through mixture proportioning and curing options to achieve desired properties, to the in-place early-age and long-term performance of the concrete in its fresh and hardened states. Both mechanical and transport properties are considered in detail. Perspective is established based on a brief review of current practices being employed nationally. Each topical section is concluded with a practice-based set of recommendations for the design and construction community. The report is intended to serve as a valuable resource to these communities, providing both a research summary and a guide to practical steps that can be taken to achieve the optimum performance of these sustainable concrete mixtures.

Book excerpt: Computational Modelling of Concrete and Concrete Structures contains the contributions to the EURO-C 2022 conference (Vienna, Austria, 23-26 May 2022). The papers review and discuss research advancements and assess the applicability and robustness of methods and models for the analysis and design of concrete, fibre-reinforced and prestressed concrete structures, as well as masonry structures. Recent developments include methods of machine learning, novel discretisation methods, probabilistic models, and consideration of a growing number of micro-structural aspects in multi-scale and multi-physics settings. In addition, trends towards the material scale with new fibres and 3D printable concretes, and life-cycle oriented models for ageing and durability of existing and new concrete infrastructure are clearly visible. Overall computational robustness of numerical predictions and mathematical rigour have further increased, accompanied by careful model validation based on respective experimental programmes. The book will serve as an important reference for both academics and professionals, stimulating new research directions in the field of computational modelling of concrete and its application to the analysis of concrete structures. EURO-C 2022 is the eighth edition of the EURO-C conference series after Innsbruck 1994, Bad Gastein 1998, St. Johann im Pongau 2003, Mayrhofen 2006, Schladming 2010, St. Anton am Arlberg 2014, and Bad Hofgastein 2018. The overarching focus of the conferences is on computational methods and numerical models for the analysis of concrete and concrete structures.

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.

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.
