Figure 5From: Transformation of meta-stable calcium silicate hydrates to tobermorite: reaction kinetics and molecular structure from XRD and NMR spectroscopy27Al{1H}CP-MAS NMR of tobermorite (t = 24 h sample). These data show polarization transfer from both sites in which CP transfer is greater for the [4]Al site at 65 ppm than for the site at 58 ppm (solution:solid of 5:1).Back to article page
