摘　　要：超高性能混凝土(UHPC)是一种强度极高、耐久性极佳的新型水泥基复合材料,钢纤维的掺入能有效提高其韧性,使其在建筑工程领域有很好的应用前景。对国际、国内主要研究成果进行归纳,介绍UHPC的制备原理,对UHPC的组成材料、配合比及制备工艺进行分析和说明,阐述其基本力学性能、耐久性及应用方式。Ultra-high performance concrete （UHPC） is a new kind of cementitious material with good applica- tion future in civil engineering, because of ultra high strength and high durability. High toughness can be acquired for UHPC by incorporating steel fibers. By collecting and analyzing international and domestic research results, the pre- paration principles of UHPC are introduced, the raw materials, mixture proportions and preparing techniques of UH- PC are analyzed, the mechanical properties and durability of UHPC are described, and the application and development of UHPC are summarized.
