混凝土技术的突破之一是超高性能混凝土(UHPC)，其钢样抗压强度高达250N/mm2，即使与高性能混凝土相比，耐久性也有显着提高。与钢纤维相结合，现在可以设计可持续的丝状轻质混凝土结构，无论是否有额外的钢筋。到目前为止，大跨度梁、桥梁、壳体和高耸塔架是扩大混凝土应用范围的理想应用。此外，法国和荷兰还在一些人行天桥上修建了交通繁忙的公路桥。德国的桥梁也已经在建设中。已经开发了一系列新的混凝土配方，以涵盖越来越多的应用。法国和德国最近公布了涵盖材料和设计方面的技术建议。本文将报告超高性能混凝土在欧洲的研究和应用状况，以及超高性能混凝土的材料和设计方面，并将根据2004年在卡塞尔举行的超高性能混凝土国际研讨会介绍最新进展。
One of the breakthroughs in concrete technology is ultra-high-performance concrete (UHPC) with a steel like compressive strength of up to 250 N/mm2 and a remarkable increase in durability compared even with high-performance concrete. In combination with steel fibers it is now possible to design sustainable filigree, lightweight concrete constructions with or even without additional reinforcement. Wide span girders, bridges, shells and high rise towers are ideal applications widening the range of concrete applications by far. In addition, e.g. to some pedestrian bridges heavily trafficked road bridges have been built in France and in the Netherlands. Bridges are already under construction in Germany as well. A wide range of new concrete formulations has been developed to cover an increasing number of applications. Technical recommendations have recently been published in France and Germany that cover material as well as design aspects. The paper will report on the state of research and application of UHPC in Europe, on material and design aspects of UHPC and will present the state-of-the-art based on an international Symposium on UHPC held in Kassel in 2004.
