FIELD: physics.
SUBSTANCE: model for compressing rock when evaluating its freeze-thaw resistance consists of a rod of the analysed material, component metal holders with depressions into which the ends of the rod enter, and a fixing structure between supports and ends of the rod. The fixing structure is based on cement which expands during solidification. The depressions in the holders have the least cross sectional area where the rod enters the holder, perpendicular to the axis of the rod.
EFFECT: increased accuracy of determining type of construction materials from freeze-thaw resistance, reduced labour input and cutting on number of tests.
