Abstract: While Ultra-High Performance Concrete (UHPC) has been under research and development for more than 20 years, it is still a relatively new material technology compared to conventional concrete. The use of this technology is slowly increasing and gaining acceptance in numerous applications, such as bridges, architectural products, security, water / waste-water, building elements and others. It is the superior mechanical properties of UHPC, particularly durability and tensile ductility that provide the benefits and reason for potential users of the technology, irrespective of the challenges of deploying this technology. The challenge of the lack of codes and standards is one major factor in slowing the implementation of UHPC. 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 Swiss Institute of Engineers and Architects (Switzerland), the French Society of Civil Engineers (France), the Japanese Society of Civil Engineers (Japan) and others. Early in 2016 the Canadian Standards Association formed two Task Groups to develop guidelines for the standardization of UHPC and fibre-reinforced concrete. The first Task Group is drafting the Materials and Methods Standard for UHPC and the second Task Group is drafting a Structural Design Guideline for Bridges for tension softening and hardening fibre reinforced concretes.
This paper covers the Canadian approach to standardizing UHPC including the background, a brief outline and the main points of the new materials, methods and the structural design of bridges with fibre-reinforced concretes, including UHPC.
