Structure of Calcium silicate hydrate (C-S-H) phase in cement

I know it is not related to the LAMMPS,
but does anyone know how to obtain the atomic geometrical structure of Calcium silicate hydrate (C-S-H) phase in cement based material?
is there any algorithm or software for doing that?

Mehdi,
The concrete sustainability hub at MIT lists several articles on
atomistic simulations on cement phases.
The link below might be a good place to start.
