C-(A)-S-H derived from tobermorite with statistically distributed sites and exemplary marked coordination spheres. The central main-layer Ca–O polyhedra (green) and paired silicate tetrahedra (gray) are encompassed by bridging silicate tetrahedra and charge-balancing Ca–O octahedra. Created with the IUCr Jmol enhanced figure toolkit (McMahon & Hanson, 2008). |
