Figure 1
Sketch of the structure of C–S–H, in the tobermorite-like assumption. (a) is a view of the layer, with yellow and purple polyhedra representing, respectively, layer Ca and layer Si coordination spheres. The ribbons of Si tetrahedra, parallel to b, are termed the wollastonite-like chains. They are detailed in (b), where all Si and vacant sites identified in the present study are assigned (see text for details). |
