Development of Non-Proprietary UHPC Mix – Evaluation of the Shear Strength of UHPC (University of Washington)

Ultra-high performance concrete (UHPC) is a relatively recent advancement in cementitious composite materials with mechanical and durability properties far exceeding those of conventional concrete, which makes it an ideal material for bridge deck joints and other connections. While considerable information has been developed about many characteristics of UHPC, information about shear behavior is sparse. This project investigates experimentally the behavior of UHPC mixes subject to a variety of stress states, focusing on shear and including variables such as mix design and fiber content. The experimental data collected in this project will be used to develop a constitutive model for the shear behavior in UHPC, and in particular the non-proprietary UHPC materials being developed by the partner universities. The testing will be conducted in a special purpose panel testing machine that is capable of applying loads to a 2-D panel in any combination of shear, tension and compression. The variables to be investigated include the mix design, the fiber content and the stress states. The expected outcome is the data on which to base a constitutive model for shear behavior in UHPC in general, and in particular the non-proprietary UHPC materials being developed by the partner universities.
