This test determines the rate and amplitude of consolidating a soil specimen laterally confined and subject to a number of successive increments of load. For this automatic model, the incremental loading in charge mode (stress) or swelling (deformation) is performed automatically for accurate performance of the test and reliable results with time saving. ACE completed with the SHEARMATIC shearing machine and the AUTOTRIAX triaxial test together constitute a unique range of automated equipment for geotechnical testing (Consolidation, shear, triaxial) in various configurations.

Key test
  • Automatic controlled trial PC
  • Incremental consolidation and axial swelling tests
  • Continuous testing 24/7 for high efficiency
  • Avoid any discrepancies related to operator error, not calibration, etc. ...
  • Data display and real-time chart
  • PC software to control up to 60 units
  • High speed LAN communication


The ACE oedometer of automatic consolidation is made of a compact loading frame equipped with two coaxial pneumatic cylinders: one for low load and one for higher loads, with automatic loading. The load is controlled by a pneumatic servo valve of high precision. Two analog channels: one for displacement sensor and one for load cell with a closed loop feedback. The testing end may be programmed in terms of time or number of bearing. The software allows the control of 60 ACE units. The test parameters are programmed by the operator. The test results are stored and displayed in real time on the PC. The data will be processed with the MS Excel spreadsheet as BS or ASTM Standards. The frame accepts all standard consolidation cells ø 50.7 to 112.80 mm. PC, consolidation cells, the worksheet and the software will be ordered separately.

The effective automation of Soils Mechanics Laboratory is not just to modernize the material but also leads to a reduction in costs. Indeed the possibility of testing 24/24 and 7/7 without interruption is of great interest. Our ACE oedometer consolidation with Automatic Machine Shearing SHEARMATIC and AUTOTRIAX, triaxial testing system is our proposal for a standalone automated laboratory. For more information, visit our website or contact our Technicocommercial Service.


Shearing Machine Automatic SHEARMATIC
  • Automatic pneumatic application of consolidation levels (up to 50)
  • Automatic test management with ability to switch from the consolidation phase to phase failure (only required manual intervention: dismantling of shear box retaining screw)
  • Accommodation box high strength polymer material
  • Easy and immediate setting of the test, visible digital display of large
  • Possibility to set different speeds and strokes (back and forward) residual shear test
  • Each bearing axial force can be applied instantaneously or by a linear ramp in a selected time interval
  • Acquisition by different and independent methods for consolidation and break phases


AUTOTRIAX, Automatic Triaxial System for Effective Stress, stress paths, permeability, unsaturated Trials
  • More than 30 possible configurations
    as required
  • Control up to three independent systems
  • Scalable and modular system
  • With appropriate accessories, allows the execution of stress path tests and tests on unsaturated soils.
