Abstract: The formation process of microstructure in cement pastes was firstly simulated with a numerical model CEMHYD3D. The influence of water-to –cement ratio and particles size on heat release and degree of hydration were then investigated. In addition, the mass of CH and C-S-H phases simulated have been verified by measuring values by Thermogravimetry-differential scanning calorimetry (TG-DSC) and XRD-Rietveld analysis. The results show that the simulated values are in good agreement with the available experimental data, indicating a good reliability of the CEMHYD3D model.
