Ultra-high-performance concrete (UHPC) continues to attract more researchers, engineers, architects, students and experts across disciplines due to its fascinating material properties. Although it is known that UHPC has excellent mechanical and durability properties, its effect on the sustainability of structures using UHPC technology in part or fully is often not quantifiable, yet. The development of mixture designs with lower carbon footprints is an exciting direction to further affect the sustainability impact of the material on our structures. In addition, the UHPC material properties offer to construct and maintain in a much more environmentally friendly way. The quantification is challenging and might remain challenging in the upcoming years. Research emphasizing life cycle analysis is underway to close part of the knowledge gap.

This course will invite national and international research groups, material suppliers and contractors to share new developments in sustainability of UHPC technology.

The contents of this course include five recorded presentations from the ACI 2023 Fall Convention:
• Is UHPC Sustainable? Holistic Assessment Through a LCA/LCC Perspective of the Material and Structural Durability by Liberato Ferrara, Polytechnic University of Milan
• Development of Sustainable Eco-UHPC with Recycled Mineral Fillers from Locally Available Industrial By-Products in Quebec by Luca Sorelli, Université Laval
• The Next Generation of UHPC Girders in Canada: Sustainable Material for Bridge Infrastructure by Philip Loh, Facca Incorporated
• Shear Behavior of UHPFRC Prestressed Girders Reinforced with Varying Amounts of Fibers by Sri Sritharan, Iowa State University
• Performance Prediction of Low CO2 and Low Cost UHPC Using Machine Learning by Deepika Sundar, Pennsylvania State University

1. Understand the environmental impact of UHPC compared to conventional concrete.
2. Analyze the use of UHPC in bridge infrastructure, comparing its environmental and structural advantages.
3. Explore recent research on UHPC behavior, focusing on the effects of fiber content and prestressing on structural performance.
4. Identify the impact of UHPC on the sustainability of our future infrastructure.
