Ultra high performance concrete (UHPC), as a cement-based composite material with ultra-high mechanical properties and durability, has attracted great interest and attention in the bridge industry since its successful development in 1993. In bridge engineering, UHPC has been applied in various aspects such as main beam structure, arch bridge main arch, waffle board bridge surface structure, bridge joints, and old bridge reinforcement. According to incomplete statistics, as of the end of 2016, over 400 bridges in various countries around the world have adopted UHPC as the main or partial building material, and over 150 bridges have adopted UHPC as the main structural material.

The ultra-high performance of new concrete is reflected in its ultra-high mechanical properties, super durability, excellent volume stability, and superior workability. Its flexural strength is three times that of ordinary concrete. Compared with the already available ultra-high performance concrete, this new type of concrete has the advantages of reducing shrinkage deformation by 50% and not requiring steam curing at room temperature, making it more cost-effective.
