  • 2.0 x 2.0 m interior space with additional anteroom (1.5 x 1.1 m)
  • Minimum room temperature: approximately -30 °C (stepless adjustable)
  • Programmable temperature cycles possible
  • complete test sequence (inclusive sample handling) within the freezing chamber under defined temperature boundary conditions
  • Saturation of samples if necessary / desired
 

Experiments

General characteristics

  • maximum force: 150 kN (maximum voltage at Ø100 mm ˜19 MPa; Ø50 mm ˜76 MPa)
  • maximum distance: 100 mm
  • Speed (stepless): 80-0,0001 mm/min

Creep tests

  • voltage or force controlled
  • Measurement of transverse strain and determination of the number of transverse strains over the duration of the test
  • Monitoring/measurement of the marginal temperatures of the sample over the duration of the test
  • Sample diameter up to 100 mm
  • additional dead load tests as long-term tests

1-axis tests

  • force or stroke controlled
  • Measurement of transverse strain and determination of the number of transverse strains over the duration of the test
  • Monitoring/measurement of the marginal temperatures of the sample over the duration of the test
  • Sample diameter up to 100 mm
