- Kay Wille, Associate Professor, University of Connecticut
- Micah Hale, Professor, University of Arkansas
- Sherif El-Tawil, Professor, University of Michigan
- Barzin Mobasher, Professor Arizona State University
- George Morcous, Professor, University of Nebraska – Lincoln
- Craig Newtson, Professor, New Mexico State University
7:45 p.m. – 8:15 p.m. Panel Discussion: Owners’ and Contractors’ Perspective – Moderated by Atorod Azizinamini, Director, ABC-UTC
All presenters in the workshop will be involved in this panel discussion along with selected DOT and FWHA personnel. Discussion will begin with questions submitted before the workshop. This session will also provide an opportunity for attendees to ask questions of all presenters.
8:15 p.m. – 8:45 p.m. Brief overview of Workshop Day 2 – Royce Floyd, University of Oklahoma
This presentation will provide a brief overview of the demonstrations that will be conducted on the second day of the workshop, which are focused on mixing UHPC in different locations and testing methods.
Session 2 – December 10, 2021: Practical Demonstration of ABC-UTC Non-Proprietary UHPC
The second half of the workshop is aimed at providing hands on experiences for mixing UHPC. Virtual demonstrations at different ABC-UTC partner universities will be carried out and using cameras at these locations; attendees will have an opportunity to view the steps in mixing UHPC and observe the mixing process in real time.
4:15 p.m. – 4:45 .p.m. Explanation of Mixing Procedures and Mixer Requirements – Royce Floyd, University of Oklahoma
This presentation will show the raw materials included in the ABC-UTC Non-Proprietary UHPC mix, discuss procedures required for mixing UHPC, and discuss the effectiveness of different types of commonly available high shear mixers. The presenter will share lessons learned from mixing the same materials at the different ABC-UTC partner institutions.
4:45 p.m. – 5:25 p.m. Demonstration of Mixing Material at Partner Institutions – David Garber, Florida International University, Royce Floyd, University of Oklahoma
This session will include demonstration of mixing the ABC-UTC Non-Proprietary UHPC mix at two of the partner institutions in real time and by video. A representative from each institution will provide a brief explanation of the slight differences in mixing procedure required for the given equipment.
5:25 p.m. – 5:40 p.m. Demonstration of Flow and Discussion of Typical Issues – Moderated by David Garber, Florida International University
A flow test will be run at each institution where demonstration batches of UHPC were mixed. The moderator will record the individual results and lead a discussion of modifications to the mix required to maintain required flowability.
5:40 p.m. – 6:00 p.m. Discussion and Demonstration of Testing Methods – Royce Floyd, University of Oklahoma
Differences in testing methods required for hardened properties of UHPC will be discussed and testing of compressive strength and flexural specimens will be demonstrated.
6:00 p.m. 6:15 p.m. Summary and Conclusions – Atorod Azizinamini, Director, ABC-UTC
