The Application and Development of Ultra-High-Performance Concrete in Bridge Engineering

Ultra-High Performance Concrete (UHPC) is a relatively new kind of matierials with excellent mechanical and durability performance compared with the conventional concrete. By making a comparison with the conventional concrete ,the compressive strength of UHPC may reach about 200MPa,which is its significant advantage and potential in applications of bridges. The performance of high tensile strength (especially with some steel fibers) enables the UHPC members to absorb energy and resist impulsive loading. In addition, because of the low porosity, the durability of the material is excellent. Based on collecting and analyzing international research results. the materials and production, and mechanical properties of UHPC were summarized. Together with a general introduction of existing international projects ,the summarization provides a comprehensive reference to further application and development of UHPC products.
