Servo Controlled Consolidation Apparatus (CRS-100)

The GCTS Consolidation Apparatus is capable of performing Controlled Gradient (CG), Constant Rate of Strain (CRS), Incremental (conventional) consolidation tests.

The GCTS Consolidation Apparatus is capable of performing Controlled Gradient (CG), Constant Rate of Strain (CRS), Incremental (conventional) consolidation tests. The CRS-100 system includes a servo controlled loading frame, stainless steel cell assembly, specimen ring, porous stones, o-ring seals, and necessary plumbing.

During the controlled gradient (CG) test, a pore pressure transducer mounted on the base provides a feedback signal, which is used in the operating software to provide a preset loading rate on the test specimen.

The constant rate of strain test (CRS) can also be performed using the GCTS Consolidation Apparatus. Using deformation sensor, which monitors axial strain on the specimen, the sample is loaded at a preset rate of strain controlled by the system software.

The conventional or incremental consolidation test is performed through application of an axial load on the test specimen at preset loading steps or increments.

This device is also capable of performing permeability tests while conducting conventional consolidation tests. Both, falling head and constant head tests can be performed using the optional PCP-100 pressure panel. Fluid flow is measured directly on the graded tubes included with the PCP-100 pressure panel. In addition, an optional volume change sensor can be supplied to automatically measure and calculate permeability values.

The GCTS CRS-100 Consolidation Apparatus includes a loading frame, load cell, deformation sensor, consolidation cell, pore pressure sensor, servo valve and the SCON1500 servo controller and data acquisition system to automatically perform the above tests. Windows software is also provided to set the tests as well as to monitor in real time the test data and data reduction.
