Summary

Bringing together in one volume the latest research and information, this book provides a comprehensive account of 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 main specifications, standards and tests in use. Aggregates in Concrete is an essential reference for concrete practitioners, academics, and researchers, and a key text for graduate students of concrete technology.
