The Soil Mechanics Laboratory is equipped and automated with specialized equipment with highly  experienced/trained personnel.

It offers technical support to civil engineering works through laboratory testing of soil mechanics and rock mechanics in geotechnical issues (PPC mines, PPC dams, etc.)

 

Main Tests

  • Soil classification tests (moisture content, particle size sieve analysis, particle size analysis using hydrometer, Atterberg limits, specific gravity)
  • Soil mechanical tests (unconfined compression tests, triaxial tests, direct shear tests, residual shear strength with the ring shear apparatus, consolidation tests, etc.)
  • Soil compaction tests (standard and modified Proctor, California Bearing Ratio CBR)

 

Main Equipment

  • Triaxial cells and load rings 5KN to 100KN
  • Direct shear apparatus
  • Ring shear apparatus
  • Mechanical and hydraulic compression oedometers
  • Automatic electric Proctor compactor
  • Full range of sieves according to ASTM standards
  • Automatic system for recording and processing mechanical tests measurements (triaxial, shear, consolidation)
