Figure 6
Main panel: HRTEM observation of a C–S–H crystal having a size of ∼6 × 20 nm, formed from hydration of C3S in the presence of additional CaCl2. Vertical and horizontal solid lines, respectively, highlight the presence of periodicities of ∼7 Å and, perpendicular, of 10–11 Å, which are more easily identified in the figure resulting from the fast Fourier transform of this image [inset (a)], this diagram being compatible with the calculated selected-area electron diffraction pattern [inset (b)] of tobermorite (Merlino et al., 1999BB37). Indexings are performed using the tobermorite (Merlino et al., 1999BB37) model.
