  The aim of presented paper is modeling of degradation processes in historical
mortars exposed to moisture impact during freezing. Internal damage caused by
ice crystallization in pores is one of the most important factors limiting the
service life of historical structures. Coupling the transport processes with
the mechanical part will allow us to address the impact of moisture on the
durability, strength and stiffness of mortars. This should be accomplished with
the help of a complex thermo-hygro-mechanical model representing one of the
prime objectives of this work. The proposed formulation is based on the
extension of the classical poroelasticity models with the damage mechanics. An
example of two-dimensional moisture transport in the environment with
temperature below freezing point is presented to support the theoretical
derivations.
