Home Test Methods Rock Testing Unconsolidation Undrained (UU) Triaxial Rock Test Equipment Unconsolidation Undrained (UU) Triaxial Rock Test Equipment An Unconsolidated Undrained triaxial test (UU test) is a constant rate of strain shearing test performed without back pressure control on the sample (i.e. the back pressure valve is closed). The test is generally quite fast as drainage is not required from the sample. There is no requirement for the sample to be saturated or consolidated before the shearing stage. Please note: Some apparatus may require additional components or software modules to perform certain tests. The following rock test equipment can perform the Unconsolidation Undrained (UU) Triaxial rock test:- Hydraulic Load Frames for Rock for unconsolidation undrained (uu) triaxial rock test 1000kN (1MN) / 2000kN (2MN) Static Compression Only Loadframe for unconsolidation undrained (uu) triaxial rock test Environmental Triaxial Testing System for unconsolidation undrained (uu) triaxial rock test Environmental Triaxial Automated System for unconsolidation undrained (uu) triaxial rock test GDS Small-Strain Hollow Cylinder Apparatus for unconsolidation undrained (uu) triaxial rock test GDS Large Diameter Cyclic Triaxial Testing System for unconsolidation undrained (uu) triaxial rock test Advanced Dynamic Triaxial Testing System for unconsolidation undrained (uu) triaxial rock test GDS Enterprise Level Dynamic Triaxial Testing System for unconsolidation undrained (uu) triaxial rock test Hydraulic Load Frames for Soil for unconsolidation undrained (uu) triaxial rock test Virtual Infinite Stiffness Load Frames for unconsolidation undrained (uu) triaxial rock test Triaxial Testing System (Automated Stress Path type) for unconsolidation undrained (uu) triaxial rock test Triaxial Automated System (Load Frame type) for unconsolidation undrained (uu) triaxial rock test
