利用29 Si MAS-NMR可以跟踪水泥和混凝土的水化程度。水化作用对硅酸盐聚合物在混凝土中的分布的影响的初步结果已知的混合设计，以及水泥的成分，被提出。文中还给出了所用砂和骨料的光谱。该技术似乎很有前途的监测混凝土硅酸盐阴离子结构及其可能与力学性能的相关性的一种手段。
The degree of hydration of cement and concrete can be followed using29Si MAS-NMR. Preliminary results of the effects of hydration on the distribution of silicate polymers in concretes of known mix designs, as well as the constituent cement, are presented. The spectra of the sand and aggregate used are also given. The technique appears promising as a means of monitoring concrete silicate anion structure and its possible correlation with mechanical properties.
