Abstract
This is the first report to show that the two 29Si-NMR signals (-86.3, -87.1 ppm) of Q2 of natural and synthetic xonotlites were clearly split, which is in accord with the crystal structure study of Kudoh et al.1 The 1H-NMR spectra were deconvoluted into three lines at 2.19, 1.86 and 5.26 ppm and assigned to structural Ca-OH, Si-OH and molecular water, respectively. The signal intensities are in good agreement with the thermogravimetric analysis.
