Growth of sheets in 3D confinements - a model for the C-S-H meso structure

A numerical model for the growth of amorphous quasi-two-dimensional structures in three-dimensional confinements is presented. Application of this model to the formation of calcium-silicate-hydrates by reaction of anhydrous cement and water, within the interstitial pore space of cement grains, leads to structures with growth and morphological properties consistent with a range of experimental data.
