The production and availability, and physical, mechanical and chemical properties of aggregate is applied to plastic and hardened concrete, and mix design, with emphasis on performance. Now with sustainability, and specialised rheological mixes; plus use of recycled and waste products; along with specifications, standards and tests.
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 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 2nd 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 learning in the field.
