ROCLAB Rock compressibility test system

ISRM suggested method

The fully automated ROCLAB system performs at in-situ temperatures, pore and bulk volume compressibility measurements of rock specimens under either hydrostatic stress, triaxial stress or uniaxial strain control. The apparatus consists of a controlled temperature pressure vessel which accommodates various loading platens with different diameters and three servo-controlled syringe pumps to respectively control the pore, radial and axial pressures. A diametral extensometer is utilized for radial strain measurement during compressibility tests while radial deformations are obtained with three LVDT sensors. An in-vessel strain-gaged load cell provides a direct reading of the axial force applied to the specimen.
