固体核磁共振作为一种十分理想的强大的分析手段,已在水泥及水泥水化产物研究领域得到了广泛的应用。本文在介绍核磁共振基本原理以及固体核磁共振技术的基础上,重点介绍了~(27)Al和~(29)Si核磁共振在水泥熟料矿物分析、水泥及其他水泥掺合料的水化产物分析、水化过程研究中的应用情况,评价了目前固体核磁共振技术在水泥领域存在的问题,并展望了其在无机非金属材料领域的发展趋势。
As a very ideal and powerful analytical tool, solid-state nuclear magnetic resonance has been widely used in the research of cement and cement hydration products. Based on the introduction of the fundamental principles of NMR and solid state nuclear magnetic resonance (NMR) technology, this paper focuses on the analysis of ~ (27) Al and ~ (29) Si NMR in cement clinker analysis, hydration products of cement and other cement admixtures Analysis and hydration process, the existing problems of solid state nuclear magnetic resonance technology in the field of cement are evaluated, and its development trend in the field of inorganic non-metallic materials is prospected.
