FIELD: construction.
SUBSTANCE: method to detect frost resistance of a coarse filler in concretes by means of saturation of investigated concrete with water and their cyclic freezing-thawing is characterised by the fact that prior to testing a surface layer is removed from the samples, thus baring grains of a coarse filler. Thickness of the removed layer makes at least a half of a diameter of coarse filler grains, and hardness of bare filler grains is detected in process of cyclic freezing-thawing.
EFFECT: detection of actual frost resistance of a coarse filler in concretes, with simultaneous detection of kinetics of filler grains destruction and mortar fraction.
