Sprayed Concrete Technology [Hardcover]

The process of spraying concrete is one of the most versatile concrete placing techniques, and is used in a wide range of applications - 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.
