摘要
偏高岭土是优质活性掺合料,是高岭土在适当温度下脱水形成的无水硅酸铝。其在混凝土强度与耐久性提升方面发挥了积极的作用,取得了较大的研究进展,但在水泥土中应用研究方面略显不足。本文综述了偏高岭土在不良地基处理与工业废料固化处理方面的研究现状,并对偏高岭土水泥土力学性能、耐久性能、微观结构、固化机理四个方面的相关研究成果进行介绍,指出目前研究存在的问题和未来的发展方向,为推动该新型材料在水泥土中的研究和应用具有重要的指导意义。
Metakaolin is a high-quality active doping material and is formed the waterless silicate aluminum by dehydration at the appropriate temperature for kaolinite.It has played an active role in the improvement of concrete strength and durability and has made great progress in research,but it is slightly inadequate in the application and research of cement soil.This paper summarized the current research status of metakaolin in the treatment of bad foundation and the curing treatment of industrial waste.The relevant research results from the four aspects of mechanical properties,durability,microstructure and curing mechanism for metakaolin cement soil were summarized in this paper,and the existing problems and development direction in the future were pointed out,which is of great significance to promote the research and application of this new material in the cement soil.
