New direct shear box for testing on fractured material<br />
<br />
<br />
<br />
<br />
For testing of intact or fractured rock<br />
Measure direct shear strength, friction and<br />
deformation behavior<br />
Conductivity of fracture during normal<br />
stress and shear at high stresses<br />
Applications related to CO2 storage and<br />
testing of shale gas<br />
Main Features<br />
• Max specimen dimensions 150x150x300 mm.<br />
• Max shear force: 250 kN<br />
• Max shear displacement: 100 mm<br />
• Max normal force: 500 kN<br />
• Max pore pressure: 2 MPa<br />
• Max flow gradient: 4 MPa<br />
• Future option for ultrasonic velocity transducers<br />
