Entwicklung eines brandbeständigen ultrahochfesten Betons für hochdynamische Beanspruchungen

Development of an ultra high strength concrete with increased resistance to fire and explosive loading

In recent years, the German Government exceedingly deals with the consequences of extreme events such as natural disasters, technical accidents and terrorist attacks. In 2007, the program "Research for Civil Security" was set up by the German Federal Ministry of Education and Research (BMBF) which aimed at solutions for the handling of such menaces.
Particularly the breakdown of public transport buildings (e. g. tunnels, bridges) is supposed to involve a drastic undersupply of general public in case of attack. To avoid that, the load bearing capacity of these buildings has to be enhanced. In this context, an ultra high strength concrete with increased resistance to fire and explosive loading was developed within the research project AISIS. The project results are presented within this article.
