Figure 3
Variation in the position of the C-S-H basal reflection as a function of structural Ca/Si ratio. Published XRD patterns having too weak a diffraction intensity or showing the presence of high amounts of portlandite were excluded. Note that the actual Ca/Si ratio may be slightly overestimated for samples from Renaudin et al. (2009BB50) that have Ca/Si > 1.5, because of the presence of portlandite in their XRD pattern.
