The PC-series passive triaxial cell serves as a chamber in which cylindrical rock specimens can be subjected to both axial and radial compression loading. Triaxial stresses are imposed by applying a circumferential confining pressure, in tandem with an axial load. The cell must be placed in a dedicated axial load frame. The sample is fitted into a Teflon sleeve between hardened steel endcaps and the assembly is immersed in confining pressurized oil. Electrical feed-through connectors, integrated into the cell base, permit the installation of in-vessel instrumentation, e.g. axial and radial deformation measurement devices, ultrasonic platens, and other special transducers to be used. Top & bottom pore fluid ports for pore pressure tests at both upper and lower platens are an integral part of the cell architecture. A low friction loading piston is provided with the triaxial cell. Different diameter platens, pistons and additional feed-through connectors can be supplied to perform custom sample geometry tests. If required, the cell can also be provided with a heating system.
