Abstract：Ultra High-Performance Concrete (UHPC) has ultra-high mechanical properties and ultra-high durability, which can better adapt to the current trend of largescale and complex civil engineering structures in civil engineering, and meet the requirements of sustainable development for the development of highperformance materials. It is considered as one of the most excellent cement-based materials in the past 30 years. In recent years, UHPC materials and structures have become a hot topic in civil engineering. The number of UHPC-related patents and papers is growing exponentially. The number, scope and area of UHPC applications are increasing greatly. Various specifications and standards are also being developed and revised. Based on the research and engineering application status of UHPC, this paper summarizes the performance characteristics of UHPC, describes the application status of UHPC in the fields of bridge engineering, construction engineering and protection engineering, and discusses the key challenges of large-scale application of UHPC in combination with the experience of the authors’ team in the application of UHPC. It can provide reference for further research and application of UHPC materials in the future.
