FIELD: measurement equipment.
SUBSTANCE: instrument is fixed with set direction of load application at a chipping element at the angle to the surface of the measurement area. The load is applied from the power cylinder to the chipping element with the specified speed to the moment of rib chipping. The value of the applied force is fixed, and concrete strength is determined. The force from the power cylinder is applied directly to the chipping element, at the same time the specified direction of load application is matched with the axis of the power cylinder.
EFFECT: higher accuracy of concrete strength determination.
