ABSTRACT
In this paper, we connected both cement research on nanoscale and sub-microscale with FEM method. By adopting parameters transfer and cohesive zone model, C-S-H globule was calibrated from MD results as solid element and interaction between C-S-H globules was represented by cohesive element in The FE software ABAQUS. Then according to the LD/HD C-S-H distribution generated by a particle’s placement algorithm, we constructed C-S-H RVE model under 250 nm by assembly C-S-H globule and inserted with cohesive element. Validated by Bolomey formula, this model well exhibits strong coherent results between density and tensile/shearing performances. Finally, we compared mechanical properties under tensile loading for both perfect adhesion and cohesive adhesion.
