| 介绍了超高性能混凝土（UHPC）的制备原理和性能特点，对UHPC国内外研究和应用情况进行了综述，指出了我国UHPC研究和应用中存在的问题。结果表明：UHPC是一种具有优异的力学性能、耐久性能和环保效益的新型水泥基复合材料。国外在UHPC理论研究和应用研究方面都取得了大量成果，在实际工程中已经获得了广泛的应用；近年来我国在理论研究和应用方面也得到了快速发展；如何简化UHPC制备工艺、降低生产成本、补偿自收缩是今后的主要研究方向，完善相关规范标准以更好地指导UHPC现浇工程应用是目前首要解决的问题。随着环保和可持续发展理念的日益重视，UHPC这种低碳环保材料将有广阔的发展前景。 |
| 英文摘要: |
| The preparation principle and performance characteristics of UHPC are introduced， the research and application of UHPC at home and abroad are reviewed， the problems in research and application of UHPC in China are pointed out. The results show that it is a new cement-based composite material with excellent mechanical properties， durability and environmental benefits. A lot of achievements have been made in theoretical research and applied research of UHPC abroad， it has been widely used in practical engineering. In recent years， we have achieved rapid development in theoretical research and application. How to simplify the preparation process of UHPC， reduce the production cost and compensate the self shrinkage are the main research directions in the future. At present， the first problem is to perfect of our country UHPC construction standardiz. With environmental protection， sustainable development being more attention， UHPC has excellent prospects for development. |
