Stress Path Triaxial and Uniaxial Fully Automatic Test System for Rock Testing Equipment

CONTROLS Stress path triaxial and uniaxial automatic test system is designed to test various materials, from soft sandstone to high strength marbles.
The test system comprehends:

• ADVANTEST ROCK, servo-hydraulic control consolefor axial load application in conformity with the relevant Standards. Includes a dedicated software for triaxial testing which also controls the SERCOMP ROCK and automatically determines the sample failure envelope. The ADVANTEST ROCK performs loading-unloading ramps and can also be used for load/stress/displacement/strain controlled testing on concrete, fiber reinforced concrete, shotcrete, etc. (with the suitable options and accessories)
• SERCOMP ROCK. Servo-hydraulic control consolefor confining pressure control into the Hoek cell (triaxial test only). It runs as a remotely controlled unit, fully operated by the Advantest Rock software. Includes 4 additional channels for strain / displacement transducers.
• ADVANCED SOFTWARE: ADVANTEST ROCK and SERCOMP ROCK are linked to a single PC for data acquisition and results elaboration.The overall test information and readings are always available on the PC screen:
• Axial load and sample strength
• Hoek cell confining pressure
• Sample deformation measured by strain gauges and external displacement transducers
• Plus any additional load/strain/displacement readings from external transducers that may be useful for research purposes.
• HIGH STIFFNESS COMPRESSION FRAMEto be selected from the wide CONTROLS product range, conforming to the size of the sample and the expected strength. Due to the typical high strength and fragility of rocks we recommend high capacity test frame (4000kN or 5000kN capacity).
• **HOEK CELL:**various models for different sample size are available: from AX type with dia. 30.10 mm up to HQ type for core with dia. 63.5 mm.

Triaxial test is carried out automatically with multiple failure stages: from a single specimen it is possible to plot the entire failure envelope,
