FIELD: construction.
SUBSTANCE: invention is intended for measuring of frost boil deformation, compressibility at thawing and filtration coefficient in several cycles of freezing-thawing in laboratory conditions. Device comprises a cartridge for sample, a punch with a stock, a tray with water, a heating element and a heat insulating casing. Device is additionally equipped with a heat insulating diaphragm, floating on water surface, and porous tubular probes passing through holes in the punch, while cartridge walls are perforated.
EFFECT: possibility to obtain values of filtration coefficient during cyclic freeze-thaw actions, as well as to simulate frost boil when adding water along the side surface of the sample.
