The interaction of methylene blue dye with calcium-silicate-hydrate
The interaction of methylene blue (MB) dye solution with various calcium-silicate-hydrate (C-S-H) preparations (C/S ratio = 0.60 to 1.80) was investigated. Experiments were also performed by treating the C-S-H in lime-saturated water and distilled water. The effects of MB on the X-ray basal spacing and the degree of polymerization were determined using low-angle X-ray diffraction (XRD) and 29.Si MAS NMR spectroscopy. An interaction mechanism tor C-S-H-MB using a 'bridging' model for the C-S-H nanostructure is proposed. The model is consistent with the XRD and 29.Si MAS NMR results.
