Unconfined Compressive Strength Testing System

Unconfined Compressive Strength System

For prices: call +44 (0)118 945 3737 or Email us
The Unconfined Compressive Strength Testing System is designed to apply a steadily increasing axial compression to a cylindrical specimen of cohesive soil or soft rock until failure occurs.

A VJ Tech Advanced TriSCAN Pro Load Frame (or a Triplex Advanced Frame (50 kN (11240 lbf) only)) is used to apply the compressive force (measured with a Load Cell) with the axial compression measured using an LSCT Displacement transducer.

The test provides an immediate approximate value of the compressive strength of the specimen and Young’s Modulus.

The Poisson ratio can be calculated when using On-Sample strain gauges or transducers.

The Test is controlled from a PC running our Clisp Studio software, with easy Test setup, control and monitoring and results analysis.
