The durability of certain products used in roofing tiles depends on the boundary
conditions during freezing as well as the texture of the porous material. The
present article is an attempt to understand the effect of these boundary conditions
on the physical state of the liquid phase during its solidification. From the
experimental strains, the pressure developed in the porosity is calculated and thus
the pressure of crystallization is identified. This step allows the pressure of the
liquid phase to be deduced. For saturated products, the water is subjected to an
overpressure during the freezing test and placing a wet cloth in contact with the
tiles can increase its magnitude.
