Ultra High Performance Concrete (UHPC)

Ultra High Performance Concrete (UHPC) not only offers superior compressive strength but also extraordinary ductility and far more durability than ordinary concrete. It enables to build structures which are sustainable and economical and come with light and filigree appearance at the same time.During the last four years, since the First International Symposium on Ultra High Performance Concrete held in Kassel in 2004, UHPC has gained much more attendance all over the world, being it by different types of applications for interesting structures or by research on the material itself and the optimization of its production and behaviour. Much of this work has been presented and discussed at the Second International Symposium on Ultra High Performance Concrete in Kassel in 2008 in more than 100 lectures. The presentations have given a broad survey of all aspects of UHPC including raw materials, micro- and macro-structures, mechanical behaviour, durability as well as of construction and design specifications appropriate for this material. Exciting architectural concepts and many examples of interesting engineering applications have been presented at the symposium. von Fehling, Ekkehard
