The Unconfined Compression Test is a laboratory test used to derive the Unconfirmed Compressive Strength (UCS) of a rock specimen. Unconfirmed Compressive Strength (UCS) stands for the maximum axial compressive stress that a specimen can bear under zero confining stress. Due to the fact that stress is applied along the longitudinal axis, the ...

Unconfined compression test for determining shear strength

Sep 26, 2011 Unconfined compression test. The main difference between Unconfined compression test and triaxil compression test is that in this test the confining cell pressure is kept zero during the test, in fact it is a special case of triaxial test. Due to which without applying any lateral pressure like a concrete crushing test the cylindrical soil sample is crushed to failure.

Jul 03, 2012 The unconfined compressive strength (UCS) of intact rocks is an important geotechnical parameter for engineering applications. Determining UCS using standard laboratory tests is a difficult, expensive and time consuming task. This is particularly true for thinly bedded, highly fractured, foliated, highly porous and weak rocks. Consequently, prediction models become an attractive alternative ...
