The rock-mechanical laboratory belonging to the Department of Rock Mechanics / Rock Engineering carries out state-of-the-art scientific and standard lab tests.
Standard tests are offered for rocks, concrete and other brittle materials, for instance compressive tests, splitting tensile and bending tensile tests, permeability and water content determination, ultrasonic measurements etc. including the derivation of appropriate material parameters such as strength, stiffness and hydraulic properties.
For scientific investigations, several triaxial cells as well as a true triaxial apparatus with servo-hydraulic testing technology are available. In compression and extension experiments, both the pre- and post-peak properties can be determined. Fully coupled hydro-thermo-mechanical experiments can be carried out. During loading ultrasonic measurements as well as AE monitoring can be conducted simultaneously. The servo-controlled triaxial machines can also simulate cyclic or dynamic loads up to 400 Hz. A special device allows to perform freeze-thaw-cycles (-30°C to + 100°C).
