Molecular dynamics of C–S–H production in graphene oxide environment
Reviews on Advanced Materials Science, 2022 The process of calcium silicate hydrate (C–S–H) generation in graphene oxide (GO) nanoslits was investigated via molecular dynamics simulations using the structural polymerization reaction of silica chains in the synthesis of silica gels.

Nano-scale mechanics of colloidal C–S–H gels [PDF]
Soft Matter, 2014 Gels of calcium-silicate-hydrates (C-S-H) are the glue that is largely responsible for the mechanical properties of cement. Despite their practical relevance, their nano-scale structure and mechanics are still mainly unexplored, because of the difficulties in characterizing them in a complex material like cement.

Densification of C-S-H measured by H NMR relaxometry [PDF]
, 2012 The nanoscale morphology of, and pore water interactions in, calcium silicate hydrate (C-S-H), the active component of cement, remain uncertain. H-1 nuclear magnetic resonance (NMR) can fully characterize the nanoporosity of C-S-H in as-prepared material
