The compression test apparatus measures the impact of vertical stress on an undisturbed soil sample. During the measurement the soil water matrix, compression stress and vertical displacement are measured simultaneously.
This apparatus applies pressure from the top for a fixed amount of time and measures how the soil responds. It operates fully automatic, and under computer control, using multifunctional software for executing set measurement protocols and both numerical and graphical visualized data presentation. All measured parameters are logged.
The samples are taken in a soil sample ring Ø 4.06 x 3.94 in (103 x 100 mm), height 1.18 in (30 mm), contents 235 cc.
Applications
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.
