STANDARDS : BS 1377:5; ASTM D2435, D3877, D4546; AASHTO T216 CEN ISO/TS 17892-5

The one-dimensional consolidation test of a soil sample enables to ascertain the settlement characteristic over a given period of time. Loads are applied with progressive increases and the settlement values are read on a dial gauge. Tests are carried out on specimens prepared from undisturbed samples. Data obtained from these tests together with classification data and a knowledge of the soils loading history, enables estimates to be made of the behavior of foundations under load.

 

The High Pressure Consolidation Test Set is complete with Front Loading Oedometer, Bench for 3 Consolidation Oedometer, Ø 50 mm Consolidation Cell, 10x0,01 mm Analog Dial Gauge and 64 Kg Set of Weights.

 

The ASTM Consolidation Test Set is complete with Front Loading Oedometer, Bench for 3 Consolidation Oedometer, Ø 63,5 mm Consolidation Cell, 10x0,01 mm Analog Dial Gauge and 64 Kg Set of Weights.

 

The BS/EN Consolidation Test Set is complete with Front Loading Oedometer, Bench for 3 Consolidation Oedometer, Ø 75 mm Consolidation Cell, 10x0,01 mm Analog Dial Gauge and 80 Kg Set of Weights.

 

The other accessories are optional.

 

The Front Loading Oedometer is rigidly manufactured from aluminum alloy casting to provide a high degree of accuracy with any frame distortions under load. The frame is designed to load the specimen through a lever arm assembly and one of three alternative beam ratios as 9:1, 10:1 and 11:1. The beam is fitted with a counter balance weight and beam support jack. The cell platform will accept the complete range consolidation cells and is fitted with a central spigot to ensure accurate centering of the cell under the loading.

 

The fixed ring Consolidation Cells are manufactured from corrosion resistant materials and conform to the requirements of the relevant

standards.

 

Apparatus for prepare Consolidation Samples and Calibration Disc shoul be ordered separately.

 

Consolidation cell, dial gauge or displacement  transducer and data logger, bench, weights, apparatuses for prepare Consolidation samples and calibration disc should be ordered separately.

 

Data Acquisition & PC Software

The  consolidation software is developed according to ASTM D2435, D3877, D4546, BS 1377:5 and AASHTO T216 standarts to use with static unilogger systems. The displacement transducers are connected to unilogger and unilooger is connected to PC by RS232 serial output.

 

The software is capable monitoring the chance of displacement data over times. The user can start recording of vertical displacement and stop current recording proses. The user can enter time intervals(or select fixed time intervals) and stress for calculattion consolidation test data.

 

The consolidation software have 8 different columns which can be set to different normal load values. The user can also manually enter the vertical displacement to these columns. The time-displacement pairs are drawn to square root time and logaritmic time graphs. .

 Features of the Digital Consolidation Test Machine

 

Graphical data  on  the  screen  is  refreshed  simultaneously during test procedure

Features Of the Software

The  Robu software continously updates load and displacement until the end of test. When the test is completed, the sharpest slope of the graph is calculated. The point that this line crosses displacement axis is commented as an offset. This offset is subtracted from the displacement value at peak point and called as flow.
