LABORATORY STUDIES

Our geotechnical laboratory carries out the study and test of soils and water with high professionalism in accordance with standards ASTM, BS and GOST. The management of our laboratory gives instructions according to the highest quality standards while operating in compliance with standards “ISO 17025”, General requirements for the competence of testing and calibration laboratories” certifying that the laboratory is a ‘Testing laboratory”.

The following tests are conducted for soils:

These tests are conducted by the standard ГОСТ.
1. Granulometric composition (sand, dust, clay fraction)
2. Natural humidity
3. Dense (volume weight), in natural and dry forms
4. Dense of solid particles
5. Porosity in % and the coefficient of porosity
6. Full moisture capacity
7. Humidity rate
8. Fluidity limit, Plasticity number and plasticity limit
9. Consistency (the indicator of fluidity)
10. Relative swelling
11. Sedimentation or tendency to sedimentation
12. Slope angle in sands
13. Relative deformation mm/mm
14. Deformation module kgg/cm²
15. Sedimentation module
16. R_{0 –} Conditional and calculation pressure
17. Cohesive force
18. Internal friction angle
19. Chemical analysis of aqueous extract (SO₄ and Cl aggressiveness) salinity, hardness
20. Chemical analysis of water
21. One axis rock
These tests are conducted by standards ASTM and BS.
