Fully automatic melting and solidification instrument

Function:

1. Standard consolidation tests can be conducted: graded loading consolidation test, CRS consolidation test, CRL consolidation test; It is also possible to conduct consolidation tests on three samples in series simultaneously, which can control the drainage conditions of each sample.

2. Reverse pressure saturation consolidation test can be conducted;

3. Can conduct long-term creep consolidation tests and measure pore pressure in real-time;

4. Various consolidation tests can be conducted at different temperatures;

5. Conducting experiments on the thawing process of frozen soil can measure parameters such as thaw settlement coefficient.
