Abstract

The development and utilization of marine resources are becoming the focus of all countries. However, the special characteristics of the marine environment pose severe durability challenges to traditional concrete materials. Ultra-high performance concrete (UHPC) has gradually been widely used in marine engineering due to its excellent durability and corrosion resistance. This paper discusses the basic concept of UHPC and its mechanism of action, evaluates its current application in marine engineering, and analyzes the challenges of its application in the marine environment. On this basis, this paper looks forward to the future development direction of UHPC in marine engineering, pointing out that with the progress of material science and construction technology, UHPC will play a greater role in the research and development of new types of structures and the improvement of construction technology, and promote its wide application in marine engineering.
