Liya Test Consolidation test set is based on consolidation amount and velocity measurement under vertical and axial pressure by providing drainage from the top and bottom surface of the water saturated and undisturbed soil sample whose lateral deformation is prevented.
The uniaxial consolidation test is used to determine the consolidation properties of soils with low permeability.
Consolidation cell, upper and lower porous stone, pressure pad, cutting ring and body, collapse clock, 50 Kg Weight Set and loading arms with 9: 1, 10: 1, 11: 1 ratio, 3 oedometer capacity are supplied as a set.
Data Acquisition & PC Software
4 or 8 channel interface units for data acquistion are used for recording displacement data over time.
- High resolution : 260.000 points.
- Serial port for PC and printer connection.
- CPU card by microprocessor 32 bit ARM risk architecture.
- 4 or 8 analogical channels for displacement transducers.
Consolidation Software is developed according to ASTM D2435, D3877, D4546, BS 1377:5 and AASHTO T216 standards. Displacement transducers are connected to interface unit and interface unit is connected to PC by RS232 serial output. The software is capable monitoring the change of displacement data over time.
User can initiate and end data recording process by using the software. The user can determine and assign different time intervals (or select fixed time intervals) and stresses for the calculation of the consolidation test data.
The consolidation software has different data recording columns each assigned to the consolidation cells and they can be set to different normal load (stress) values. The user can also manually enter the vertical displacement data to these columns for correction. The graphs of time-displacement pairs are drawn in both square-root time and logarithmic time scales. In addition to these visualizations, the software can calculate required parameters such as √t90, √t50, √t100, mv, Cv , etc. according to the related standards indicated above. Recorded data, graphs, calculations and all other generic data can be exported to Microsoft Excel for further evaluation.
- Customizable User Interface
- Graphical outputs and reports can be saved as MS Excel worksheet
- Flexibility in edit report and graph templates
