Molecular Dynamic simulation studies probing the formation and structure of C-S-H are generally computationally expensive and can reach only very short time scales. Herein, we propose a coarse graining approach to model the formation of C-S-H, using patchy particles and a modified Patchy Brownian Cluster Dynamics algorithm. The simulations show that patchy particle systems can recover the qualitative kinetic evolution of C-S-H formation, and the obtained final structures were comparable to previously reported molecular dynamics studies and experiments. The model was extended to study the effect of water in the polymerization of tetraethoxysilane oligomers, the principal component of an impregnation treatment for deteriorated concrete surfaces. The intermediate system properties predicted by the simulations, such as viscosity and gel time, and structure were found to be well in accordance with the tailored experiments.13697798enginfo:eu-repo/semantics/openAccessjournal article10.1016/j.cemconres.2021.106658Calcium-silicate-hydrate (C-S-H)CementSimulationsSilicate polymerizationCalcium-silicate-hydrate (C-S-H)CementSimulationsSilicate polymerizationBuilding and ConstructionGeneral Materials ScienceProject IDinfo:eu-repo/grantAgreement/EC/H2020/760858/EU/Innovative materials and techniques for the conservation of 20th century concrete-based cultural heritage/InnovaConcreteinfo:eu-repo/grantAgreement/EC/H2020/760858/EU/Innovative materials and techniques for the conservation of 20th century concrete-based cultural heritage/InnovaConcreteFunding InfoThe work described in this manuscript has been performed under InnovaConcrete EC project, supported by funding from the European Union's Horizon 2020 Research and Innovation Programme under Grant Agreement N◦760858.
