The process of spraying concrete is one of the most versatile concrete placing techniques, and is used in a wide range of application - from construction of new tunnels, domes, tanks and pools, to repair and strengthening of existing structure. The steady growth in interest and application in the technique is reflected in this book, which brings together current international developments in materials, application, repair, specifications and testing. Sprayed Concrete: Materials, Applications and Performance forms the proceedings of the International Conference organised by the American Concrete Institute and the Sprayed Concrete Association in Edinburgh, Scotland, September 1996. Over thirty contributions from international experts make this book essential for concrete technologists world-wide who need to keep fully up to date with advances in the subject.
