Study of geoprocesses with complementary mechanical and electromagnetic wave measurements in an oedometer

Particulate geomaterials can be uniquely studied with wave-based techniques. Electromagnetic and mechanical waves interact with the tested material, exciting different phenomena and revealing different information. Complementary wave measurements were implemented in a modified oedometric cell to study and to monitor different processes in geomaterials. The cell and the measuring devices are discussed, followed by a presentation of typical measurements conducted during consolidation, chemical diffusion, and cementation. The paper also includes a discussion of the most common computations and analyses involved in this type of test.
