The RILEM conference "Use of Superabsorbent Polymers and Other New Additives in Concrete", 15-18 August 2010, Lyngby, Denmark, is scientifically sponsored by RILEM through the technical committee: TC 225-SAP Application of super absorbent polymers in concrete construction. The event is hosted by the Department of Civil Engineering at the Technical University of Denmark and financially sponsored by the Knud Hřjgaard Foundation.

The conference broadly concerns all aspects of the use of new additives in concrete. A major part of the conference addresses themes with relation to the aforementioned RILEM technical committee 225-SAP. Other examples of new additives covered by the conference theme include surface active agents and mineral admixtures. The contributions to the conference deal with theory, modeling and results from experimental investigations, where such new additives are used in concrete.

In addition to the above mentioned topics, two invited speakers contribute keynote talks at the conference on topics of general relevance for the audience. Hans-Henrik Bache, formerly Aalborg Portland Cement factory, makes a perspective on the ‘Development of ultra high strength concrete’. Christian Munch-Petersen, from EMCON A/S, shows the footprints of ‘Concrete for modern, large bridges and tunnels’. The latter contribution is included in this volume. All contributions have been peer reviewed.
