Direct Tension Test Method for Ultra-High Performance Concrete

Project Information

Project ID: 
Project Abstract: 

This project will 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. Test method development will be followed by assessment of the performance of multiple UHPC-class materials. Project will also include a phase wherein the efficiency of fiber reinforcement is assessed according to the test method.  One and two-dimensional structural elements will be cast and tested.


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.
