Fig. 8: Phase structure analysis during early hydration stages.
From: Molecular elucidation of cement hydration inhibition by silane coupling agents
a QXRD curves at various hydration intervals, with standard PDF cards for Ca3SiO5 and ZnO highlighted. b Phase content derived from XRD fitting analysis, where the R-value for each group is maintained below 12%. B denotes the pure water group, and S represents the silane-treatment group, with phase content expressed as the weight percentage (wt%) of the sample. c Representative TEM images at three distinct hydration times, where yellow dashed boxes highlight regions of dissolution inhibition on the surface of Ca3SiO5 particles in the silane-treatment group. The red lines mark the sedimentation of Layers A and B.
