GDS Consolidation Testing System (Rowe and Barden Type)

Product Code : GDSCTS

The GDS Consolidation Testing System (GDSCTS) is a state-of-the-art, fully-automated consolidation testing system designed for soil.

 The system is based on the Rowe and Barden type consolidation cell using GDS pressure/volume controllers  from the Advanced, Standard, or Enterprise range. Two of these pressure controllers link to the computer, one for axial stress and axial displacement control and one for setting back pressure.



Case Study:

Key features Benefits to the user
Rowe and Barden type cell: Direct stress control on specimen via either a flexible or rigid porous disk.
Flexibility in the capacity of the system: Specimen size, load, pressures can be chosen to ensure the system is created specifically to suit the testing required and the budget.
Advanced testing (ADVCTS):
Remains the leading Rowe & Barden type consolidation system for research testing throughout the world. All elements of the ADVCTS system are biased towards achieving the greatest resolution and accuracy, for the highest quality tests achievable in a research environment.
Standard testing (STDCTS):Provides a low cost alternative with all the features of the ADVCTS system with slightly reduced accuracies by using GDS standard pressure/volume controllers.
Accuracy of Pressure Measurement
STDCTS: <0.25% measured value. ADVCTS: <0.1% full range
Accuracy of Volume Measurement

STDCTS: <0.25% measured value. ADVCTS: <0.1% full range

Pressure Range (MPa)
