Marine Concrete Structures: Design, Durability and Performance comprehensively examines structures located in, under, or in close proximity to the sea. A major emphasis of the book is on the long-term performance of marine concrete structures that not only represent major infrastructure investment and provision, but are also required to operate with minimal maintenance.

Chapters review the design, specification, construction, and operation of marine concrete structures, and examine their performance and durability in the marine environment. A number of case studies of significant marine concrete structures from around the world are included which help to reinforce the principles outlined in earlier chapters and provide useful background to these types of structures. The result is a thorough and up-to-date reference source that engineers, researchers, and postgraduate students in this field will find invaluable.

Covers, in detail, the design, specification, construction, and operation of marine concrete structures Examines the properties and performance of concrete in the marine environment Provides case studies on significant marine concrete structures and durability-based design from around the world

Bringing together in one volume the latest research and information, this book provides a detailed guide to the selection and use of aggregates in concrete. After an introduction defining the purpose and role of aggregates in concrete, the authors present an overview of aggregate sources and production techniques, followed by a detailed study of their physical, mechanical and chemical properties. This knowledge is then applied to the use of aggregates in both plastic and hardened concretes, and in the overall mix design. Special aggregates and their applications are discussed in detail, as are the current main specifications, standards and tests.

This book addresses the need to resolve the ITZ's influence on engineering and durability characteristics of cementious composites, identifies the systems and properties that are affected by it, and quantifies these effects in order to prepare the base for engineering design tools. This volume presents the proceedings of the Second International RILEM conference on the Interfacial Transition Zone in cementious composites, held in Haifa, Israel in 1998.

This well-established text brings together in one volume current research and information on the selection and use of aggregates in concrete. It gives an overview of aggregate sources, production, and availability, followed by a detailed treatment of their physical, mechanical, and chemical properties. This crucial background is then applied to the use of aggregates in both plastic and hardened concrete, and in the overall mix design, with emphasis on the influence of aggregates on concrete performance.Aggregates in Concrete Second Edition includes a new chapter that deals with sustainability considerations and new material on aggregates in specialised rheological mixes. Special aggregates and their applications are discussed in detail, especially the use of recycled aggregates – from CDW and recycled concrete – and aggregates derived from industrial and agro-waste materials, as well as porous aggregates for internal curing of concrete. The main aggregate specifications, standards, and tests in use are also detailed.This book is essential for practitioners in concrete while remaining accessible for students in the field.

This book provides an up-to-date survey of durability issues, with a particular focus on specification and design, and how to achieve durability in actual concrete construction. It is aimed at the practising engineer, but is also a valuable resource for graduate-level programs in universities. Along with background to current philosophies it gathers together in one useful reference a summary of current knowledge on concrete durability, includes information on modern concrete materials, and shows how these materials can be combined to produce durable concrete. The approach is consistent with the increasing focus on sustainability that is being addressed by the concrete industry, with the current emphasis on ‘design for durability’.

All pupils at Stoneyridge School have Review sessions. The students don’t enjoy them, but understand they are used to improve their well-being and are simply a part of school life. Zane Sampson is one of these students who has learnt to live with Reviews; however, after discovering that the school is secretly using these sessions to mark its students either as Eligible or Ineligible, Zane begins to question whether Stoneyridge is being entirely honest with its pupils. Zane gradually comes to realise that he can only be sure of two things: all of his peers are being lied to, and until he unearths the actual purpose of their Reviews, he and his friends could be living in more danger than they know.

This book gathers contributions presented at the 7th International Conference on Concrete Repair, Rehabilitation and Retrofitting (ICCRRR), held in Cape Town, South Africa, on November 4–6, 2024.

This book gathers contributions presented at the 7th International Conference on Concrete Repair, Rehabilitation and Retrofitting (ICCRRR), held in Cape Town, South Africa, on November 4–6, 2024. The conference aims at sharing knowledge and experience on current developments in concrete technology, durability design and service life management, condition assessment of concrete structures, and concrete repair, rehabilitation and retrofitting. The contributions, which were selected through a rigorous international peer-review process, share exciting ideas that will spur novel research directions and foster new multidisciplinary collaborations.

This book gathers peer-reviewed contributions presented at the 5th International Conference on Calcined Clays for Sustainable Concrete (ICCCSC), held in Cape Town, South Africa, on February 4–6, 2026. Focusing on sustainable concrete technologies and applications, this book highlights the latest findings in this fast-growing field, addressing topics such as low-carbon cement production, performance evaluation, LC2 and LC3 technology, environmental efficiency, production and quality control, fresh and hardened concrete properties, service life modelling.

Concrete and cement-based materials must operate in increasingly aggressive aqueous environments, which may be either natural or industrial.  These materials may suffer degradation in which ion addition and/or ion exchange reactions occur, leading to a breakdown of the matrix microstructure and consequent weakening.  Sometimes this degradation can be extremely rapid and serious such as in acidic environments, while in other cases degradation occurs over long periods.  Consequences of material failure are usually severe – adversely affecting the health and well-being of human communities and disturbing ecological balances. There are also large direct costs of maintaining and replacing deteriorated infrastructure and indirect costs from loss of production during maintenance work, which place a great burden on society. The focus of this book is on addressing issues concerning performance of cement-based materials in aggressive aqueous environments , by way of this State-of-the-Art Report. The book represents the work of many well-known and respected authors who contributed chapters or parts of chapters. Four main themes were addressed: I. Nature and kinetics of degradation and deterioration mechanisms of cement-based materials in aggressive aqueous environments, II. Modelling of deterioration in such environments, III. Test methods to assess performance of cement-based materials in such environments, and which can be used to characterise and rate relative performance and inform long term predictions, IV. Engineering implications and consequences of deterioration in aggressive aqueous environments, and engineering approaches to the problem.
