Aggregates in Concrete
Purchasing Options
Summary
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.

Editorial Reviews
'The book ... deserves a hearty welcome ... We strongly recommend it to all those who are involved in concrete construction — ready-mixed concrete suppliers, construction engineers, concrete technologists, etc. This could also be a good reference book for academicians and students of civil engineering.' - The Indian Concrete Journal, Vol 80, August 2006, No 8.
'A useful reference for practitioners and I can strongly recommend it as a worthwhile addition to the bookshelf of any person that regularly deals with concrete as a construction material.' - Civil Engineering (South Africa)
