Ultra high performance concrete (UHPC) can be seen as one of the major breakthroughs in concrete technology in the last two centuries. The material has attracted the interest of many researchers, designers, practitioners, agencies, societies, contractors and suppliers through its excellent mechanical performance and its resistance against environmental degradation. UHPC has been investigated in numerous aspects around the world and the research effort is increasing based on the number of published journal papers and conference articles. UHPC unites people, disciplines and societies to achieve goals of high impact. Those goals are directed towards an enhancement of our safety, health and living conditions by positively impacting our environment, counteracting the degradation of the infrastructure, and by providing inspiring, sustainable and cost-efficient solutions to our current problems and to those to come.
