Abstract: The isothermal compressibilities of ice and partially and fully saturated sand and silt at -10°C are presented. The tests employ a piston-die device with which a uniaxial load is imposed on a lead encapsulated specimen, resulting in the hydrostatic compression of the test specimen. Pressures to 30 kbars are obtained. The compressibility of ice is as reported by P.W. Bridgman. The various phase transformations of ice I to water to ice V to ice VI to ice VIII appear as expected. It is shown that the compressibility of frozen soil can be readily predicted from the knowledge of material properties such as degree of saturation with ice, porosity, and the compressibilities of the ice and mineral components.
