The application of high-performance concrete (HPC) in bridge engineering has significantly enhanced the strength and durability of the structure. However, its performance is influenced by factors such as material proportioning, construction technology, and environmental conditions. Through experimental analysis and case studies, this research reveals that optimizing the water-binder ratio, selecting appropriate admixtures, and improving the construction technology can effectively enhance the durability of HPC. Protection strategies proposed for different environmental conditions, such as measures against chloride ion erosion and protection against freeze-thaw cycles, further ensure the long-term stability of the bridge. Scientific and reasonable design and construction are the keys to improving the durability of HPC, providing important theoretical basis and technical support for future bridge engineering projects.
