Project ID:FHWA-PROJ-06-0036
Project Name: Mechanical Properties of Lightweight High-Performance Concrete
Status: Active
Contact:
Last Name:Graybeal
First Name:Benjamin A (Ben)
Telephone:202-493-3122
E-mail:benjamin.graybeal@dot.gov
Office: Office of Infrastructure Research and Development
Team:Bridge and Foundation Engineering Team
Roadmap/Focus area(s): Infrastructure Research and Technology Strategic Plan and Roadmap
Project Description:This projects aims to provide recommended specifications for the mechanical properties of lightweight high-performance concrete. Recommendations will be provided to code-writing committees in order to allow for a systematic update of codes to reflect the performance of modern lightweight concrete.
Laboratories: Structures Laboratory
Concrete Laboratory
Start Date: October 1, 2006
End Date: July 31, 2013
Goals:The key project objective is to develop recommended specifications for the mechanical properties of lightweight high-performance concrete as relevant to the American Association of State Highway and Transportation Officials (AASHTO) Load and Resistance Factor Design (LRFD) Bridge Design Specification.
Test Methodology: Approach includes physical testing of multiple lightweight concrete mix designs, compilation of decades worth of lightweight concrete mechanical properties from other research efforts, probabilistic analysis of results, and creation of recommended specification provisions.
Other Information: Physical mechanical testing conducted alongside full-scale structural tests.
Expected Benefits:The expected benefit is the facilitation of a major revision of the American Association of State Highway and Transportation Officials (AASHTO) Load and Resistance Factor Design (LRFD) Bridge Design Specification, thus updating structural concrete provisions to reflect the performance of modern lightweight concretes appropriately.
