The present paper proposes the integrated multi-stage approach to predict the mechanical properties of cement paste with the function of hydration time. To this purpose, in the initial stage, volume fractions of hydration products are reliably predicted, and representative volume element (RVE) is then developed in MATLAB.Afterwards, the developed RVE is transferred to COMSOL to perform the numerical analysis, where intrinsic mechanical properties are computed. The proposed model results showed good agreement with the existing analytical model and experimental results.
