The sample is then removed for measurement of the water content.

Active view current version of standard. As for the results, the axial stress is usually plotted versus the axial strain. This standard does not purport to address all of the safety problems, if any, associated with its use. Unconfined Compression Test UCT is a simple laboratory testing method to assess the mechanical properties of rocks and fine-grained soils.

ASTM D – 06 Standard Test Method for Unconfined Compressive Strength of Cohesive Soil

The primary purpose of the Unconfined Compression Test is to quickly determine a measure of the unconfined compressive strength of rocks or fine-grained soils that possess sufficient cohesion to permit testing in the unconfined state. Copyright – Geotechdata. Principles of Unconfined Asttm Test, Chap 7. The determination of the unconsolidated, undrained strength of cohesive soils with lateral confinement is covered by Test Method D This measure is then used to calculate the asgm undrained shear strength of the clay under unconfined conditions.


Note 1 The determination of the unconsolidated, undrained strength of cohesive soils with lateral confinement is covered by Test Method D Can you edit this page? Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

The values stated in inch-pound units are approximate. Send us an email to editor geotechdata.

It is the responsibility of the user of this standard to establish appropriate safety and health practices d2166 determine the applicability of regulatory limitations prior to use. Pricing information and quote request on Geotechgate. Unconfined Compression Test Geotechdata. In general, The UCT can be conducted on rock samples or on undisturbed, reconstituted or compacted cohesive soil sample.

In addition, they are representative of the significant digits that should generally be retained. Free quote for buying Unconfined Compression Test equipment: It is beyond the c2166 of this test method to consider significant digits used in analysis methods for engineering design.


In the unconfined compression test, the sample si placed in the loading machine between the lower and upper plates.

Detailed description of Unconfined Compression Test, Chap 7. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user’s objectives; and it is common practice to increase or reduce significant digits of reported data to commensurate with these considerations.

Dry and crumbly soils, fissured or varved materials, silts, peats, and sands ast, be tested with this method to obtain valid unconfined compression strength values.
