Abstract
This paper presents an historical perspective of the development and current testing procedures of ultra-high-performance concrete (UHPC) in North America, and explores the need for specific standardized tests for UHPC. A review of the applications utilizing the UHPC technology, projects completed over the past 20 years and promising applications, such as precast bridge deck elements, field-cast UHPC connections for accelerated bridge construction, underground utility systems, architectural building components, urban furniture, security, and others, are covered. The fundamentals of the technology, material properties of UHPC, design details, project profiles, and testing methods for UHPC are included. By utilizing the UHPC material’s unique combination of superior properties including strength, durability, ductility, workability, and aesthetics in conjunction with precast elements and field-cast methodologies, the built infrastructure performance is advanced, accelerated, and improved. Benefits include: simplified construction techniques, speed of construction, improved durability, reduced maintenance, reduced out-of-service, minimum interruption, reduced element size and complexity, extended usage life, and improved resiliency.
