Material Property Characterization of Ultra-High Performance Concrete

Advances in the knowledge and understanding of the behaviors of concrete on the microstructural level have led to the development of the next generation of concrete, namely ultra-high performance concrete (UHPC). This report characterizes the material behaviors of one UHPC in terms of accepted concrete testing methodologies. The Federal Highway
Administration (FHWA) has been investigating the optimal use of UHPC in highway bridges, and this report presents results from the first phase of this research program. Of primary importance, the results contained herein provide a starting point for bridge owners interested in advancing the state of bridge engineering through the use of extremely high strength and high durability concretes. This report presents both what can be achieved today through the use of a commercially available concrete as well as the types of advancements that can be achieved by reevaluating the traditional components and proportions normally present in cementitious structural materials.
