FIELD: test technology.
SUBSTANCE: invention is intended to determine the strength of concrete and relates to destructive methods of control and increase measurement accuracy while simplifying the test procedure. Destructive load is applied to the side surface at three points located diametrically at an equal distance from each other, by means of puncturing cylindrical metal gaskets commensurate with the sample, the axes of which are arranged at an angle of 60° to each other and perpendicular to the axis of the sample.
EFFECT: ability to reduce the impact of technological, methodological and metrological factors and improve the accuracy of testing while simplifying the test procedure.
