ASTM D2166 is a cornerstone of geotechnical lab testing. While the unconfined compression test has limitations, it remains an indispensable tool for preliminary strength assessments. For critical projects, pair it with triaxial or direct shear testing.

ASTM D2166, officially titled "Standard Test Method for Unconfined Compressive Strength of Cohesive Soil," measures the unconfined compressive strength (qu) of saturated, cohesive soils. This value is then used to estimate the soil's undrained shear strength (Su), typically calculated as Su = qu/2. typically calculated as Su = qu/2.
