Astm D2166 Pdf _verified_ Online

For geotechnical engineers and laboratory technicians, determining the shear strength of cohesive soils is a fundamental task. The go-to standard for this—particularly for soils that do not require complex confinement—is ASTM D2166 . Whether you are reviewing a report or setting up a lab test, having a clear grasp of this standard is critical.

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. astm d2166 pdf
