  • Uu Triaxial Report
    Introduction The unconsolidated undrained (UU) Triaxial Test is a quick method of estimating the shear strength of a soil. The soil which undergoes the test is sheared to failure without prior consolidation meaning this test is perfect for soil samples which are undisturbed however this is never the...
