Publication date: 1999

The International Conference on the Use of Admixtures in High Performance Concrete provides a forum for presentation and discussion of state-of-the-art advances in the use of admixtures to produce high performance concrete.
In the last ten years the development of new chemical admixtures has been outstanding. The introduction of acrylic polymers,anti-corrosion chemicals, new anti-wash admixtures and more effective air entraining agents etc., has resulted in the production of concretes with better performance and durability. At the same time, the dangers arising from incompatibility when combining admixtures or using different cements with one admixture. The conference therefore will be the best forum for interchanging research results and experiences and for presenting up to date scientific and technological advances on the use of admixtures for the production of High Performance Concrete.
This publication brings together outstanding work contributed by scientists and technologists from around the world. It provides the most up-to-date information from experts in the field of chemical admixtures in concrete.
