Unconfined Compression Testing

The Unconfined Compression Testing Machine is a specialized device used to determine theunconfined compressive strength of cohesive soils, particularly saturated clays. lt applies anaxial load to a cylindrical soil specimen without any lateral confinement, simulating a zero-confining-pressure condition. This simple and efficient test method provides importantparameters such as unconfined compressive strength (qu) and undrained shear strength (su= qu/2), which are essential for geotechnical design and stability analysis. The machinetypically features a robust loading frame, a precise loading mechanism, and an accurateforce and displacement measurement system. lt is widely used in geotechnical laboratories,research institutes, and construction quality control to evaluate soil strength for foundationsembankments,and earthworks.
