摘要
对超高性能混凝土(UHPC)的发展历程进行梳理,分析了绿色环保、低成本化UHPC制备技术的研究现状,指出了UHPC在建筑工程、结构维修加固等领域的研究和应用现状,并对中国UHPC相关规范的制定情况进行了梳理。分析了当前阻碍UHPC发展的技术瓶颈,对未来发展研究的方向进行了展望。结果表明:UHPC在制备技术尤其是低碳化、低成本化研究方面有了较大的进展;UHPC生产成本仍比较高,但是在装配式结构、维修加固等方面表现出了广阔的应用前景;中国已制定一些UHPC相关技术规范与规程,但全面的标准体系建设还不完善;未来UHPC的研究将继续致力于可持续性、低成本化、完备制备技术、拓展应用领域等方面,以满足快速发展的工程建设和基础设施需求;随着可持续发展战略的推进和技术的进步,UHPC有望在工程领域发挥更重要的作用。
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.
