Special Concretes - Workability and Mixing

This book forms the Proceedings of the International RILEM Workshop held in Paisley in March 1993. It contains contributions on theoretical and practical aspects of the use of special concretes, with a particular focus on their behaviour in the fresh state.
This book forms the proceedings of the International RILEM Workshop held in Paisley in March 1993. It contains contributions on theoretical and practical aspects of the use of special concretes, with a particular focus on their behaviour in the fresh state. A significant and increasing proportion of concrete mixes differ considerably from ordinary mixes. These are used where high performance is needed or for special applications, such as high strength concrete, underwater concrete, flowing concrete, sprayed concrete. Mixes containing fibres, silica fume, polymers, special aggregates and cements, also demand a different approach to normal practice, such as the use of modified mixing equipment. Outstanding performance of special concretes can be achieved but successful applications depend strongly on the behaviour of the mixes when fresh. At present there is insufficient guidance on the properties, specification, methods of assessment and compliance testing of fresh special concrete. This book brings together expert contributions in this fast developing field and aims to assist civil engineering and concrete technologists concerned with improving the quantity and economy of construct
