PMSS Project Details

 

Project ID:FHWA-PROJ-09-0002
Project Name: Simultaneous Structural and Environmental Loading of an Ultra-High Performance Concrete Component
Status: Completed
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 project focuses on beginning to assess the long-term structural performance of an ultra-high performance concrete component, which is continuously subjected to both cyclic structural loading in an aggressive environment. An ultra-high performance concrete beam was loaded cyclically in flexure for 500,000 cycles over the course of 5 months while simultaneously having a sodium chloride solution applied to the cracked tensile face of the beam.
Laboratories: Structures Laboratory
Start Date: January 1, 2009
End Date: June 30, 2010
Goals:The key project objective is to investigate performance of ultra-high performance concrete (UHPC) when subjected to large structural loadings in the presence of an aggressive environment. The goal is to facilitate applicable use of this advanced cementitious material in the bridge inventory.
Test Methodology: Use structural testing methods to load a beam in flexure beyond its cracking limit while applying a salt solution to the tension flange.
Other Information: Pilot study testing is complete. Final report has been published.
