The paper presents the differential analysis of volumetric strain (DAVS). The method allows measurements of volumetric
deformations of capillary-porous materials caused by water-ice phase change. The VSE indicator (volumetric strain effect),
which under certain conditions can be interpreted as the minimum degree of phase change of water contained in the material
pores, is proposed. The test results (DAVS) for three materials with diversified microstructure: clinker brick, calcium-silicate
brick and Portland cement mortar were compared with the test results for pore characteristics obtained with the mercury
intrusion porosimetry.
