Alkali-Aggregate Reaction in Concrete: A World Review is unique in providing authoritative and up to date expert information on the causes and effects of Alkali-Aggregate Reaction (AAR) in concrete structures worldwide. In 1992 a first edition entitled The Alkali-Silica Reaction in Concrete, edited by Professor Narayan Swamy, was published in a first attempt to cover this concrete problem from a global perspective, but the coverage was incomplete. This completely new edition offers a fully updated and more universal coverage of the world situation concerning AAR and includes a wealth of new evidence and research information that has accumulated in the intervening years. Although there are various textbooks offering readers sections that deal with AAR deterioration and damage to concrete, no other single book brings together the views of recognised international experts in the field, and the wealth of scattered research information that is available. It provides a ‘state of the art’ review and deals authoritatively with the mechanisms of AAR, its diagnosis and how to treat concrete affected by AAR. It is illustrated by numerous actual examples from around the world, and comprises specialist contributions provided by senior engineers and scientists from many parts of the world. The book is divided into two distinct but complementary parts. The first five chapters deal with the most recent findings concerning the mechanisms involved in the reaction, methods concerning its diagnosis, testing and evaluation, together with an appraisal of current methods used in its avoidance and in the remediation of affected concrete structures. The second part is divided into eleven chapters covering each region of the world in turn. These chapters have been written by experts with specialist knowledge of AAR in the countries involved and include an authoritative appraisal of the problem and its solution as it affects concrete structures in the region. Such an authoritative compilation of information on AAR has not been attempted previously on this scale and this work is therefore an essential source for practising and research civil engineers, consultant engineers and materials scientists, as well as aggregate and cement producers, designers and concrete suppliers, especially regarding projects outside their own region.

Advanced Concrete Technology A thorough grounding in the science of concrete combined with the latest developments in the rapidly evolving field of concrete technology In the newly revised second edition of Advanced Concrete Technology, a distinguished team of academics and engineers delivers a state-of-the-art exploration of modern and advanced concrete technologies developed during the last decade. The book combines the essential concepts and theory of concrete with practical examples of material design, composition, processing, characterization, properties, and performance. The authors explain, in detail, the hardware and software of concrete, and offer readers discussions of the most recent advances in concrete technology, including, but not limited to, concrete recycling, nanotechnology, microstructural simulation, additive manufacturing, and non-destructive testing methods. This newest edition of Advanced Concrete Technology provides a sustained emphasis on sustainable and novel technologies, like new binders, 3D printing, and other advanced materials and techniques. Readers will also find: A thorough introduction to concrete, including its definition and its historical evolution as a material used in engineering and construction In-depth explorations of the materials for making concrete and the properties of fresh concrete Comprehensive discussions of the material structure of concrete, hardened concrete, and advanced cementitious composites Fulsome treatments of concrete fracture mechanics, non-destructive testing in concrete engineering, and future trends in concrete Perfect for undergraduate and graduate students studying civil or materials engineering—especially those taking classes in the properties of concrete or concrete technologies—as well as engineers in the concrete industry. Advanced Concrete Technology, 2nd Edition will also earn a place in the libraries of civil and materials engineers working in the industry.

This reference book presents the theory and methodology to conduct a finite element assessment of concrete structures subjected to chemically induced volumetric expansion in general and alkali aggregate reaction in particular. It is limited to models developed by the author, and focuses on how to best address a simple question: if a structure suffers from AAR, how is its structural integrity jeopardized, and when would the reaction end. Subjects treated are: • Brief overview of AAR: nature of the chemical reactions, AAR in both dams and nuclear power plants, and how does it impact the mechanical properties of concrete. • Constitutive model for both the AAR expansion, and concrete nonlinearities (both smeared and discrete crack models). • Validation of the model along with a parametric study to assess what are the critical parameters in a study. • Selection of material properties for an AAR finite element simulation, followed by applications in dams and massive reinforced concrete structures. • Micro Model for improved understanding of the essence of the reaction, along with a newly proposed mathematical model for the kinetics of the reaction. • Review of relevant procedures to estimate the residual expansion of a structure suffering from AAR, along with a proposed approach to determine when the reaction will end. The book is extensively illustrated with numerous figures and provides guidance to engineers confronted with swelling in concrete infrastructures.

Aggregates containing certain constituents can react with alkali hydroxides in concrete. The reactivity is potentially harmful only when it produces significant expansion. This alkali-aggregate reactivity (AAR) has two forms--alkali-silica reaction (ASR) and alkali-carbonate reaction (ACR, sometimes called alkali-carbonate rock reaction, or ACRR). ASR is of more concern than ACR because the occurrence of aggregates containing reactive silica minerals is more common. Alkali-reactive carbonate aggregates have a specific composition that is not very common. Alkali-silica reactivity has been recognized as a potential source of distress in concrete since the later 1930s. Even though potentially reactive aggregates exist throughout North America, ASR distress in structural concrete is not common. There are a number of reasons for this: 1. Most aggregates are chemically stable in hydraulic-cement concrete 2. Aggregates with good service records are abundant in many areas 3. The concrete in service is dry enough to inhibit ASR 4. The use of certain pozzolans or slags controls ASR 5. In many concrete mixtures, the alkali content of the concrete is low enough to control harmful ASR 6. Some forms of ASR do not produce significant deleterious expansion To reduce ASR potential requires understanding the ASR mechanism; properly using tests to identify potentially reactive aggregates; and, if needed, taking steps to minimize the potential for expansion and related cracking. Alkali-carbonate reaction in concrete was not documented until 1957. Although ACR is much less common, this report also briefly reviews the mechanism, visual distress symptoms, identification tests, and control measures.

This book gathers the peer-reviewed papers presented at the 17th International Conference on Alkali-Aggregate Reaction in Concrete (ICAAR), held in Ottawa, Ontario, Canada, on May 19-24, 2024. It highlights the latest advances and innovations in the field of internal swelling reactions, particularly alkali-aggregate reaction (AAR), and combined mechanisms such as delayed ettringite formation (DEF). The conference topics encompass understanding the reaction mechanisms and the affecting factors; testing methods and preventative measures; diagnosis, evaluation, and prognosis; monitoring and NDT; structural effects and modeling at all scales; repair and remedial measures; and combined mechanisms (e.g., DEF). The contributions, which were selected by means of a rigorous international peer-review process, present a wealth of exciting ideas that will open novel research directions and foster new multidisciplinary collaborations.
