Abstract:"The term Ultra-High Performance Concrete (UHPC) refers to a relatively new class of advanced cementitious
composite materials whose mechanical and durability properties far surpass those of conventional concrete. This
class of concrete has been demonstrated to facilitate solutions that address specific problems in the U.S. highway
bridge infrastructure. Initial material development research on UHPC began more than two decades ago. First
structural deployments began in the late 1990s. First field deployments in the U.S. highway transportation
infrastructure began in 2006. For this study, UHPC-class materials are defined as cementitious-based composite
materials with discontinuous fiber reinforcement that exhibit compressive strength above 21.7 ksi (150 MPa),
pre- and post-cracking tensile strength above 0.72 ksi (5 MPa), and enhanced durability via a discontinuous pore
structure.
The report documents the state of the art with regard to the research, development, and deployment of UHPC
components within the U.S. highway transportation infrastructure. More than 600 technical articles and reports
covering research and applications using UHPC have been published in English in the last 20 years, with many
more published in other languages. The report includes information about materials and production, mechanical
properties, structural design and structural testing, durability and durability testing, and actual and potential
applications. The report concludes with recommendations for the future direction for UHPC applications in the
United States."
