Abstract

In the field of civil engineering, with the rapid development of global climate change and industrialization, the durability of building materials has presented unprecedented challenges. For this challenge, this paper innovatively studies the durability of ultra-high performance concrete (UHPC) in extreme environmental conditions. Through systematic experimental research and theoretical analysis, this study discusses the remarkable effect of fiber enhancement, nanomaterials application and surface treatment technology in improving UHPC durability, and proposes an improvement scheme for the existing durability test method. The experimental results revealed that the UHPC modified by carbon nanotubes showed excellent performance in resisting freezing and thawing and salt erosion, while the application of waterproof layer significantly improved the durability of UHPC. In addition, this study also proposed comprehensive protection measures, including fiber enhancement, waterproof layer and anticorrosive coating, which can significantly improve the durability of UHPC in extreme environments. The study also looks into the future to further optimize the UHPC design and improve its application performance in various extreme environments to promote the wide application and development of UHPC in the civil engineering field. The findings of this study not only provide the theoretical basis and technical support for the wide application of UHPC in extreme environments, but also provide new solutions for realizing the sustainable utilization of resources, which has important scientific significance and application value.
