Abstract
Previous research has indicated that Ultra High-Performance Concrete (UHPC) is highly effective in providing reliable connections between precast concrete components, particularly in Accelerated Bridge Construction (ABC) applications. While several proprietary UHPC products are available in North America, one significant drawback is their considerable cost. To address this issue, the bridge industry has increasingly turned its attention to non-proprietary UHPC as a cost-effective alternative. Given the recent advancements and applications of non-proprietary UHPC in bridge engineering, this study aims to explore current trends and insights, emphasizing its growing importance in the U.S. bridge sector. The paper begins with a bibliographic study to identify recent research trends in the field of UHPC materials. It then focuses on the development of non-proprietary UHPC by various researchers across the United States using locally available materials. Finally, the study investigates the development of UHPC utilizing materials available in Idaho and evaluates the overall strength and failure mechanisms of non-proprietary UHPC in closure pour connections between precast components.
