The one-dimensional consolidation test, or oedometric test, provides information on the compressibility of a sample restrained laterally while subjected to vertical load. The test can be performed in order to determine the correlation/ratio between the applied pressure and the resulting deformation, or between vertical deformation and time during which a constant pressure is applied. A cylindrical sample is inserted in a non-deformable metal ring and placed between two porous stones (to ensure water drainage and optimal amount of moisture).
Two versions of Oedometer are available: a version with manual application of weights typically used for educational purposes, and a version with fully automatic loading steps application.
