摘　　要：活性粉末混凝土作为新型超高强、高耐久的水泥基复合材料,在土木工程领域具有广阔的应用前景。然而,目前由于活性粉末混凝土材料与普通混凝土内部结构差异较大,其微观机理的研究尚不够深入,还难以为材料组成、制备技术以及材料宏观性能的进一步优化提供理论支持。总结了国内外学者利用MIP、BET、NMR、XRD、TGA、EDS、SEM以及ESEM等研究方法对活性粉末混凝土材料微观结构与机理的研究成果。并在此基础上,对活性粉末混凝土材料在组成、微观形貌以及孔结构等微观研究中存在的问题及其发展方向进行了分析与讨论。As a new type of ultra-high strength and high durability cement-based composite materials,reactive powder concrete owns promising applications prospects in civil engineering field.However,the internal structure of reactive powder concrete materials are quite different compared with the ordinary concrete,the study on microscopic mechanisms of this material is still insufficient,so it is difficult to provide theoretical support for further optimization of the material compositions,preparation technology and microscopic properties.The microstructure and properties test of reactive powder concrete materials using MIP,BET,NMR,XRD,DTG,EDS,SEM and ESEM carried out by the scholars at home and abroad are introduced.Moreover,the existing problems of materials composition,microscopic morphology,pore structure and development prospects are analyzed and discussed.
