Development of an Ultra-High Performance Concrete Precast ...

31-12-2006  Ultra-high performance concrete (UHPC) is in a relatively new class of cementitious materials. These concretes demonstrate good durability properties, high compressive strength, and usable tensile resistance. The high compressive and useable tensile resistance can lead to smaller and more efficient precast cross sections.
