Unconfined compressive strength is the highest axial compressive stress that a cohesive soil specimen can withstand in the absence of a confining stress (UCS).
The unconfined compression test is the most widely used technique for assessing soil shear strength since it is among the quickest and most affordable. It is generally utilized for recovering cohesive, saturated soils from sampling tubes with thin walls.
The Unconfined Compression Test is a laboratory procedure used to determine a rock specimen's Unconfirmed Compressive Strength (UCS). Unconfirmed Compressive Strength (UCS) is the highest axial compressive stress a specimen can withstand in the absence of any constraining load.
A cohesive soil specimen's maximum axial compressive stress under no confining tension is known as unconfined compressive strength (UCS). One of the quickest and least expensive ways to determine a clayey soil's shear strength is the unconfined compression test.
