GAUGING TUBE FOR EQUIPMENT USED FOR LOGGING CONCRETE ADHESIVNESS

摘要

The calibration tube consists of a tube with a diameter equal to the cemented column, closed at one end with a flexible cap, in which a probe with sound transducers is inserted. The probe is equipped with appropriate centralizers. In one version of the invention, the tube has a standard diameter and is closed with a flexible cap at one end that has an axial hole through which a probe fastening threaded cap is inserted. In this case the probe is equipped with a single centralizer at its upper end.
