Abstract: The present paper presents a detailed description of a model elaborated to predict the behavior of hydrated cement systems subjected to sub-freezing temperatures.
The model was developed within the framework of poromechanics and accounts for local thermodynamic equilibrium between various phases.
Ice formation is described at the pore scale and its effects on the thermoporoelastic behavior of the homogenized porous medium are considered.
Basic numerical considerations are formulated.
A comparison with experimental results illustrates the ability of the model to predict the volume instabilities of hydrated cement pastes upon freezing.
