中文摘要：
作为新型水泥基复合材料,活性粉末混凝土具有高强度,高韧性以及高耐久性等优异性能,在桥梁与路面工程、建筑工程、水利工程和特种结构等领域拥有广阔的应用前景.但由于组成中活性组分多,内部结构复杂,微观机理研究尚不够明确,难以为材料的宏观性能提供明确的理论依据.介绍了活性粉末混凝土的基本组成、各组分产生的反应及影响因素,总结了国内外学者对活性粉末混凝土微观形貌及孔结构等的研究成果,更进一步地提出了现阶段微观层面研究和材料本身所存在的问题,指出了发展趋势,并进行了分析和讨论.
英文摘要：
As a new type of cement-based composite materials, with ultra-high strength, high toughness and high durability, reactive powder concrete has promising applications prospects in bridge and road engineering, architectural engineering, hydraulic engineering and unique construction. However, since there is much active component, and the internal structure of reactive powder concrete is complex, the study of microcosmic mechanism is not definite, it is difficult to provide theoretical support for the macro-properties of the material. The basic composition of reactive powder concrete, the reaction of them and the influencing factors among these components were introduced. The microstructure and pore structure of reactive powder concrete by the scholars at home and abroad are introduced. Further, the existing problems of micro-level research at the present stage, the material and the development prospects are analyzed and discussed.
