Shear and Compression Test Apparatus
The compression and shear test apparatus measures both the compression and shear resistance of an undisturbed soil sample.
- User-friendly and easy operation
- Accurate measurement principles
- Simultaneous operation of up to 8 instruments
- Upgradable or dynamic multistep operation with advanced sensor-based experiment control
- Graphical instrument overview and data zoom functions
- Software-controlled measurement protocols
This instrument measures how prone the soil is to slip under both vertical and horizontal stress. This is very useful in research prior to the construction of dikes, railways, large and heavy buildings or other engineering applications that put a lot of stress on the soil.
During shearing at a constant shear velocity and under either consolidated drained (CD), unconsolidated, undrained (UU) or unconsolidated drained (UD) conditions, the matric potential and shear forces at a given vertical stress are measured simultaneously.
The apparatus operates under computer control, using multifunctional software for executing measurement protocols and visualised data presentation. Samples are taken in a soil sample ring sized Ø 103 x 100 mm, height 30 mm, contents 235 cc.

The apparatus was developed in cooperation with Christian Albrechts University Kiel in Germany, a leading institution in soil compaction research. Read the interview with Prof. Horn of Kiel University for more information.
