Topic Description:
Ultra-high performance concrete (UHPC) is one of the major breakthroughs in concrete technology in the last two centuries. It is a fiber-reinforced, cementitious material that offers exceptional mechanical and durability performance, including compressive strengths exceeding 22,000 psi and excellent resistance against environmental degradation. For this reason, UHPC is being considered for a wide variety of structural and architectural applications to provide innovative design solutions. The Federal Highway Administration (FHWA) has taken significant interest in this material as part of their Every Day Counts program to promote accelerated bridge construction (ABC) through the use of prefabricated bridge elements. Field-cast UHPC is used in this case to join prefabricated elements on-site to form simple, strong, durable connections for improved long-term performance. Over 180 bridges throughout North America have been constructed using this type of system. This presentation will discuss what UHPC is, what characteristics it exhibits, the advantages to using it, and the various structural applications that have proven successful over the years.
