Unconfined Compression Test UCT is a simple laboratory testing method to assess the mechanical properties of rocks and fine-grained soils.

The values stated in inch-pound units are approximate. Note 1 The determination of the unconsolidated, undrained strength of cohesive soils with lateral confinement is covered by Test Method D Active view current version of standard. Pricing information and quote request on Geotechgate.

E2166 sample is then removed for measurement of the water content. Free quote for buying Unconfined Compression Test equipment: Copyright – Geotechdata.

In addition, they are representative of the significant digits that should generally be retained. Detailed description of Unconfined Compression Test, Chap 7.

It is beyond the scope of this test method to consider significant digits used in analysis methods for engineering design. The determination of the unconsolidated, undrained strength of cohesive soils with lateral confinement atm covered by Test Method Ashm 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 astmm of reported data to commensurate with these considerations.


Dry and crumbly soils, fissured or varved materials, silts, peats, and sands cannot be tested with this method to obtain d21166 unconfined compression strength values.

As for the results, the axial stress is usually plotted versus the axial strain. 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.

Can you edit this page? This measure is then used to calculate the unconsolidated undrained shear strength of the clay under unconfined conditions. In general, The UCT can be conducted on rock samples or on undisturbed, reconstituted or compacted cohesive soil sample.
