Analyses and models of the autogenous shrinkage of hardening cement paste. II. Modelling at scale of hydrating grains
Our previous paper (Hua/1995/) has studied the autogenous shrinkage at macroscopic scale. One can also model the autogenous shrinkage at the scale of the hydrating grains without going into the colloidal details of the hydrates. At this scale, hydrates (including the immobilised water held by micropores) are considered as homogeneous isotropic viscoelastic and locally non-ageing. For the ensemble of the material, only the percentages of heterogeneities (hydrates, residual anhydrous cement, capillary water, etc.) vary during the process of hydration. The modelling is based on the mechanism of capillary depression for the same cement paste as that studied in the previous paper with a modelling at macroscopic scale (CPA 55 with W/C = 0.42). The result agrees well with measurement.
