For triaxial stress-strain experiments on cylindrical specimens: triaxial multistage tests to examine the post-failure reaction, stabilizing or intermittently increasing the surface pressure is possible. The rise in the axial tension takes the path of force or is expansion-controlled.
For:
- cylindrical rock and soil cores with a length/diameter ratio of 2:1
Standard
- DIN 18137-2, Issue:1990-12 Building ground, tests and testing
- equipment; determining the lateral resistance; triaxial test
- ISRM recommendations
- if required, the national recommendations can be taken into account
Accuracy
- Class 1
Size
- max. surface pressure: 1500 bar
- max. temperature inside cell: 200 °C
Options
- specially designed compression test frame for carrying out triaxial strength tests in the inset with a triaxial cell
- equipment to facilitate transportation into the testing room
- separately controllable pump aggregate for the hydraulic supply of the compression testing machine / pressure intensifier
- pressure intensifier for producing the pore pressure in the triaxial cell so the specimen is continually subjected to flow-through with controlled fluid pressures
- safety system (surface pressure > pore pressure)
- tension measuring and controlling equipment for determining the longitudinal and lateral deformation on cylinders
- ultrasonic test unit
- tempering equipment to control the temperature inside the cell
- digital measuring and controlling electronic system DIGIMAXX® C-21
