MEASUREMENT OF PORE-SIZE DENSITY FUNCTION IN SAND.

A study is presented on characterization of sand fabric by means of the pore-size distribution, which allows the engineer to indirectly but quantitatively examine the sand fabric. The term 'pore-size distribution' is clarified so that a better link is established between the terminology used in the literature of mercury porosimetry and that used in the conventional probabilistic approaches in geotechnical engineering. A technique has been verified satisfactory for preparation of sand specimens for mercury intrusion tests, which make possible the measurement and determination of the pore-size distribution and the density function in sand. Data deduction and typical pore-size distributions and density functions for the sands studied are presented and discussed.
