Evolution of the position from the 001 reflection in experimental data (dots, same data as in Fig. 3[link]) and in a hypothetical random (R0) interstratified structure (solid line) built of layers of plombierite-like layers [d(001) = 14 Å] with interlayer calcium omitted yielding a Ca/Si ratio of 2/3 and of layers of tobermorite MDO2 from Urals [d(001) = 11.3 Å] with the occupancy of interlayer calcium (Ca2 in Merlino et al., 2001BB41) increased to 0.5 and all Si bridging tetrahedra omitted, yielding a Ca/Si ratio of 5/4.  [article HTML]
