Abstract:: The development of ultra-high performance concrete (UHPC) was reviewed, and the research status of green, environmentally friendly and low-cost UHPC preparation technology was analyzed. The main application status of UHPC in the field of architectural engineering and structural maintenance and reinforcement were pointed out, and the formulation of relevant standards and specifications of UHPC in China was sorted out. Based on the analysis of the current technical bottlenecks that hinder the development of UHPC, the direction of future development research was prospected. The results show that great progress has been made in the preparation technology of UHPC, especially in the research of lowcarbon and lowcost. The cost of UHPC production is still high, but it has shown broad prospects in the maintenance, reinforcement and prefabricated structure. Some UHPC related technical specifications and procedures have been formulated in China, but the comprehesive standard construction system is not yet perfected. The future research of UHPC will continue to focus on sustainability, reducing costs, improving preparation technology, expanding application fields, etc., to meet the rapid development of engineering construction and infrastructure needs. With the continuous advancement of sustainable development strategy and the advancement of technology, UHPC is expected to play a more important role in the field of engineering.
