Special Tests on Rock

The following list is types of tests offered:

• Simple shear tests on rock joint with roughness angle measurement.
• Uniaxial compression tests on rock or concrete/rock contact at dam/foundation interface.
• Free swell test on shales and shaly rocks.
• Semi-confined swell test for stress-dependent swelling.
• Null swell test for suppression pressure of rock or concrete expansion under AAR reaction.
• Calcite content test.
• Salinity of pore fluid in rock.
