Abstract: While Ultra-High Performance Concrete (UHPC) has been under research and development
for over a quarter of a century, it is still a relatively new material technology compared to
conventional concrete. Due to the superior properties of UHPC, it is slowly gaining acceptance in
numerous applications, such as bridges, architectural products, security, water / waste-water,
building elements and others throughout the world. The lack of UHPC specific codes and
standards, a lack of understanding and comfort by the general practioner, and a common
agreement on what exactly is UHPC are some of the major factors in slowing the implementation
of this technology.
Several jurisdictions have commenced the process of writing standards for UHPC, such as the
American Concrete Institute (USA), the American Society of Testing and Materials (USA), the
Canadian Standards Association (Canada), the Swiss Institute of Engineers and Architects
(Switzerland), the French Society of Civil Engineers (France), the Japanese Society of Civil
Engineers (Japan), Korean Concrete Institute (Korea), China Concrete & Cement-based Products
Association (China), Scientific Technical Spanish Association of Concrete(Spain) and others.
The majority of these standards writing bodies as well as National Specifying Agencies all differ
slightly on what they consider as UHPC in their respective documents.
This paper discusses the various international bodies’ approach to standardizing UHPC
including the global history of UHPC development, a brief synopsis of the mechanical properties
in each international document, and an introduction to a global definition for UHPC.
