(a)–(c) The α-C₂S structure along (a) the c axis, (b) the b axis and (c) the ( $[{\overline 2} {\overline 1} 0]$ ) direction. (d)–(f) The average structure of $[\alpha_H^{\prime}]$ belite along (d) the a axis, (e) the b axis and (f) the c axis. (g)–(i) The β-C₂S structure along (g) the b axis, (h) the a axis and (i) the c axis. (j)–(l) The structure of γ-C₂S along (j) the a axis, (k) the c axis and (l) the b axis. Panels (a), (d) and (g) correspond to the ∼7 Å direction, (b), (e) and (h) to the ∼5 Å direction, and (c), (f) and (i) to the ∼9 Å direction. The viewing directions of γ-C₂S are selected accordingly for proper comparison. The projections in (b), (e), (h) and (k) display the original cell of α-C₂S as dashed black lines to illustrate the formation of tetrahedron pairs in $[\alpha_H^{\prime} {\hbox{-}} {\rm C}_2 {\rm S}]$ . The structures are displayed as 2 × 2 × 2 of the respective unit cells. Ca is displayed in purple, Si in orange and O in red.
