The Precast/Prestressed Concrete Institute (PCI), the Federal Highway Administration (FHWA) and the Fédération Internationale du Béton (fib) are co-sponsors of an International Symposium on High Performance Concrete to be held September 25-27, 2000, in conjunction with the PCI Annual Convention and Exhibition in Orlando, Florida.
The PCI/FHWA/fib International Symposium will address research, design, construction, performance, and benefits of High Performance Concrete (HPC). HPC is engineered to achieve enhanced durability and/or strength characteristics while ensuring adequate constructability. Topics addressed at the Symposium will include:
General History, Marketing, and Implementation
The history and definition of HPC, modeling service life, lifecycle analysis, marketing, and implementation of HPC for bridges.
Materials and Mix Design
Material properties, mix design, use of admixtures, durability, placeability, and avoidance of delayed ettringite formation.
Laboratory Research and Future Direction
Research on fresh concrete properties, strength, durability, ductility, high performance grout, reactive powder concrete, and new materials including development, testing, and application of FRP and other non-metallic, corrosion-resistant reinforcement.
Quality Concepts, Fabrication, and Transportation
Quality control, curing procedures, test methods, instrumentation, placement, and use of quality systems to produce durable high strength concrete products. Fabrication and testing of bridge girders, prestressing techniques, delivery to the jobsite, and erection of prestressed concrete members.
Construction Techniques
Techniques, systems, methods, or procedures that facilitate construction, including transportation and placement of HPC.
Structural Design and Concepts
Design aspects of HPC including optimization techniques for slab design layout and seismic behavior of high strength structural elements, repair, and rehabilitation.
Structural Performance and Code Requirements
Evaluation of structural performance in terms of creep, shrinkage, camber, and other long-term behavioral characteristics. Current ACI and AASHTO Code provisions including limits and required changes relevant to high strength concrete.
FHWA Showcase Projects and Case Histories
Overviews and summaries of the demonstration projects sponsored by FHWA and various state departments of transportation, including follow-up reports on their performance. Highlights from projects that have incorporated HPC including problems and limitations.
