摘　　要：在配制水泥基材料过程中,利用活性材料替代部分水泥,可提高基体的力学和耐久性能,同时还可减少水泥用量,对节能减排有重大帮助。近年来偏高岭土(MK)活性材料开始受到广泛关注和研究,其对水泥基材料性能的影响研究也有重大进展。主要综述了MK对水泥基材料力学性能的影响研究进展,主要包括含杂质煅烧高龄粘土以及纯MK对砂浆和混凝土的早期和后期力学性能影响,MK与石灰石粉(LF)复掺对水泥基材料力学性能以及MK对超高性能混凝土(UHPC)的力学性能影响,最后对MK-水泥基材料的未来研究方向进行了展望。It can not only improve the physical and durability properties of matrix but also can help saving energy and decreasing carbon dioxide emission greatly by lessening usage amount of cement that is replaced by pozzolanic materials partly while producing cement-based materials.In recent years,metakaolin(MK)is noticed and researched extensively as a pozzolanic material.The research which metakaolin influence the properties of cement-based materials have prominent progress.The research progess on the physical property that metakaolin influence cement-based materials were summarized.It included the research that impure calcined kaolin clay and pure metakaolin influence the early and later physical propeties of mortar and concrete,the research that the compound addition of MK and limestone powder(LF)influence the mechanical properties of cement-based materials and the research that MK influence the mechanical properties of ultra high performance concrete(UHPC)primarily.Finally,the research orientation on the metakaolin cement-based materials in the future was prospected.
