Abstract:
     In the said method, the permeability pressure and green compression strength of samples for compactness test are first measured directly and these two parameters of normal technological samples are then found out based on the linear relationship. In this tester, a displacement sensor is used to measure the compactness, a pressure sensor to measure the green compression strength and a barometric sensor to measure the permeability recpectively. All the operations are executed under the control of a microcomputer.
