The RTX-1500 from GCTS is an advanced triaxial testing system engineered for high-precision rock mechanics experiments under true in-situ stress conditions. Designed to evaluate strength, deformation, and fluid transport behavior, the system supports both static and dynamic loading scenarios with thermal and pore pressure control.
Key Specifications:
Axial Load Capacity: Up to 1500 kN (e.g., 2.9 GPa for Ø1″ samples; 740 MPa for Ø2″)
Confining Pressure: Up to 140 MPa
Pore Pressure: Up to 140 MPa
Temperature Control: 20–200 °C
Strain Rate: Up to 10⁻³ s⁻¹
Displacement Measurement: 2 axial + 1 circumferential LVDTs (±2.5 mm)
Integrated Capabilities:
Servo-controlled axial actuator for precise loading
SCON-2000 digital control system for real-time automation and high-speed data acquisition
HPVC-140 intensifier for stable pressure control
CATS software for test programming, monitoring, and data analysis
ISCO pumps for controlled injection of CO₂, H₂, or other fluids
Ultrasonic transducers for in-situ P- and S-wave velocity measurements
