Abstract
A simple and accurate method for automatic measurement of volume changes of saturated test specimens in laboratory tests is described. In this method, the volume change of water in a burette is measured with use of an extremely sensitive differential pressure transducer. Any value of back pressure less than 3000 kN/m2 can be used in this method. The volume change is monitored with a digital voltage meter. The sensitivity of the method is 0.006 ml/mV over a range of 25 ml or 0.0013 ml/mV over a range of 5ml.
