✦ Synopsis

Cement paste is the matrix material for concrete and cement based composites. This paper presents a molecular dynamics (MD) method for estimating mechanical properties of hydrated cement major constituents: calcium-silicate-hydrate (C-S-H) structurally related tobermorite 14 Γ… and jennite, and calcium hydroxide (CH). Microporomechanics technique is used to calculate properties of two types of C-S-H, namely, low density (LD) and high density (HD) C-S-H gels. Simulation results reported by the authors were compared with existing computational and experimental values. This research is intended to give a general step to study the complicated cement hydrated products from a multiscale view.
