Main Features

  • Advanced testing system suitable for extremely variable materials, from soft sandstone to high-strength marbles
  • Determination of Elastic modulus, Poisson's ratio and strength characteristics of rock specimens under uniaxial and triaxial conditions including permeability measurement
  • Automatic performance of triaxial tests with combined control of axial load and confining pressure
  • Multiple failure stages triaxial test (stress – path mode) carried out automatically, the entire failure path is derived from a single specimen including post-peak softening phase
  • Suitable for prolonged tests
  • 19 bit effective resolution
  • Also suitable for load, stress, displacement and strain-controlled testing on concrete, fibre-reinforced and shotcrete specimens (with the relevant options and accessories)
  • Fully programmable test procedures including axial load and confining pressure levels and combinations
  • Integrated data acquisition and results elaboration including failure envelope plotting
  • Extremely flexible system ideal for research purposes
  • tecnical specifications
    • Scroll the table
