I. Overview
Strain controlled consolidation tester is used to test soil samples under continuous loading at a constant strain rate. The soil sample is subjected to limited lateral and axial pressure for drainage, and the deformation and pore water pressure changes of the specimen during the test process are measured to determine the consolidation amount and rate of the soil sample. This instrument is suitable for saturated fine soil particles.
This instrument mainly consists of a constant strain loading control system, a computer data acquisition and processing system, a loading testing machine, a consolidation container (detachable seal), and stainless steel ring cutters and other accessories.
2, Characteristics
1. LCD display, strain rate loading.
2. The time required for the experiment is relatively short (half of the time required for traditional consolidation tests).
3. Specialized software for real-time monitoring and display.
4. The evaluation of consolidation and compression parameters is more reliable.
5. Software functions
(1) Real time collection and storage of consolidation loading force values, consolidation compression deformation, and changes in sample pore pressure (pore pressure dissipation process).
(2) Automatically draw data graphs of axial pressure and compression deformation, time and pore pressure. Experimental data can be freely exported and printed for users to view and analyze.
(3) According to the experimental requirements, the sampling frequency can be set arbitrarily.
(4) Preset test stop conditions: Time can be pre-set; Compression deformation can be pre-set; Upon reaching the preset conditions, the machine will automatically shut down and stop collecting data.
