Devices and methods for testing cement include: a pressure vessel with a sample container inside an interior working volume of the pressure vessel, the pressure vessel configured to supply a first pressurized fluid to control a pore pressure of a cement sample and to supply a second pressurized fluid to lateral exterior surfaces of the sample container to provide a confining pressure that can be different than the pore pressure.
