It provides a measures of the undrained strength and the stress-strain characteristics of the rock or soil.Unconfined Compressive Strength (UCS) is the load per unit area at which an unconfined cylindrical specimen of soil will fail in the axial compression test. If the axial compression force per unit area has not reached a maximum value even at 20 percent axial strain, the UCS shall be taken as the value obtained at 20 percent axial strain.

Unconfined compression test is a quick test to obtain the shear strength parameters of cohesive (fine grained) soils either in undisturbed or remolded state. It is also known as uniaxial compression test. Unconfined compression test is a special case of a triaxial test, where confining pressure is zero.
The unconfined compression test is conducted using the procedures in ASTM D2166/D2166M-16 . When conducting an unconfined compressive test, a cylindrical sample, with a height to a diameter ratio of at least two, is mounted into the unconfined compressive strength testing device, as shown in Fig. 24. It is subjected to an axial load until failure.

Unconfirmed Compressive Strength (UCS) stands for the maximum axial compressive stress that a specimen can bear under zero confining stress. Due to the .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 .
1 D 2166 will fail in a simple compression test. In this test method, unconfined compressive strength is taken as the maximum load attained per unit area or the load per unit area at 15 % axial strain, whichever is secured first during the performance of a test. 3.2.2 shear strength (su)—for unconfined compressive strength test specimens, the .Unconfined Compression Strength test atau pengujian kuat tekan batuan utuh untuk menentukan kuat kekuatan batuan intact dengan sampel berbentuk silinder hasil dari pengeboran full coring.
