Project ID:	FHWA-PROJ-10-0030
Project Name:	Direct Tension Test Method for Ultra-High Performance Concrete
Status:	Active
Contact:	Last Name: Graybeal First Name: Benjamin A (Ben) Telephone: 202-493-3122 E-mail: benjamin.graybeal@dot.gov
Organization:	Federal Highway Administration - Turner-Fairbank Highway Research Center (TFHRC)
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 aims to develop a test method for the assessment of Ultra-High Performance Concrete (UHPC) tensile mechanical properties. Existing test methods do not effectively relate these properties, resulting in hesitancy from anyone considering the use of UHPC. A practical test method that directly relates the important engineering response will support the continued expansion of UHPC materials in the highway infrastructure.
Laboratories:	Structures Laboratory Concrete Laboratory
Start Date:	July 1, 2010
End Date:	September 30, 2013
Funding Amount:	$50,000.00
FHWA Program Name:	Ultra-High Performance Concrete with Ductility
Goals:	The objective of this research program is to develop a practical, reliable test method that relates the full range of uniaxial tensile response of Ultra-High Performance Concrete (UHPC)-class materials. This tensile response includes both elastic and inelastic behaviors, with the inelastic behaviors including the generation of multiple tightly spaced cracks bridged by internal fiber reinforcement.
Project Type:	Onsite
Background Information:	Data not yet available
Test Methodology:	Conduct a series of physical tests applying a direct tensile load to Ultra-High Performance Concrete (UHPC) components. Iteratively assess response and adjust test method.
