Uniaxial Test for Rocks
Uniaxial Test

The GCTS Uniaxial Testing System was designed to easily perform uniaxial compression and uniaxial tension tests on a rock specimen. Through the use of advanced software and a closed-loop, electro-hydraulic servo, these tests can be automated, resulting in very little input from the operator. 


The GCTS Uniaxial Testing System features:


  • Load capacity up to 4,500 kN (1,000 kips) for both tension and compression tests
  • Frame stiffness up to 5,000 kN/mm
  • Can perform static or dynamic tests
  • Capable of performing bending, indirect tension, fracture, creep, and other material tests
  • Can be used with a GCTS triaxial cell to perform triaxial tests
  • Other load capacities and specimen dimensions available

The GCTS Uniaxial Testing Systems (UCT Series) are easy-to-use systems for the determination of the unconfined compressive strength of cylindrical specimens. The axial actuator is computer-controlled using our state-of-the-art SCON-1400 Wireless Servo Controller and Data Acquisition System and our 64-bit Windows-based software. The system is capable of performing static and dynamic closed-loop tests by controlling the load, deformation, stress, strain or any other measured or calculated parameter. All test measurements can easily be viewed and exported for rapid analysis of results.

On-specimen deformation instrumentation, triaxial cells, and other testing instrumentation can be provided.
