Simulation of the Influence of Intrinsic C-S-H Aging on Time-Dependent Relaxation of Hydrating Cement Paste. Academic Article uri icon


  • The viscoelastic/viscoplastic behavior of cement paste may occur due to intrinsic calcium silicate hydrate (C-S-H) viscoelasticity/viscoplasticity and cement grain dissolution during the hydration process. A numerical model that combines a microstructure model and a finite element calculation model has been developed to predict the time-dependent behavior of cementitious materials based on these two mechanisms, while incorporating C-S-H intrinsic aging. The simulation results from the model suggest that when considering C-S-H aging, the time-dependent properties of C-S-H are capable of generating the aging effect of cement paste, and can become a significant mechanism leading to the overall relaxation of cement paste.
