Theoretical basis for dissolution-induced viscoelastic and viscoplastic behavior of cementitious materials
While the macroscale viscoelastic/viscoplastic behavior of cementitious materials is well-documented and has been extensively modeled from a phenomenologieal perspective, the mechanisms (and their relative importance) of the viscoelastic/viscoplastic response of such materials is still subject to debate. In this paper, theoretical basis is presented for viscoelastic/viscoplastic behavior in cementitious materials owing to time-dependent phase dissolution and resulting stress and strain redistribution. Two time scales are considered via consideration of hydration-induced dissolution processes (early age) and stress-induced dissolution processes (early or later age). Based on thermodynamic considerations, viscoelastic behavior of cementitious materials due to phase dissolution effects is entirely plausible and warrants further investigation.
