Figure 2From: Transformation of meta-stable calcium silicate hydrates to tobermorite: reaction kinetics and molecular structure from XRD and NMR spectroscopyPowder diffraction data of a physically separated solid cake. The top layer shows reflections at 7.8 2θ (002), 29.1 2θ (220), and 30.1 2θ (222) that are indicative of 11 Å tobermorite (White Square) while the bottom layer shows one broad reflection at 29.5 2θ due to CSH (Black Circle).Back to article page
