The chapter discusses the unconfined compression test, detailing its significance in determining the unconfined compression strength of soil specimens. It describes the conditions under which the test is performed and how the results, indicated by the axial stress at failure, can be utilized to assess soil consistency. The relationship between the degree of saturation and unconfined strength is also emphasized, presenting an essential aspect of testing for both saturated and unsaturated soils.
