Unconfined Compressive Strength Test Equipment

D2166 d2166m 16 standard test method for unconfined compressive strength of cohesive soil.

Unconfined compressive strength test equipment.

Unconfined compressive strength ucs is a quick and simple test to determine the undrained shear strength of cohesive soils. For soils the undrained shear strength su is necessary for the determination of the bearing capacity of foundations dams etc. The undrained shear strength su of clays is commonly determined from an unconfined compression test. In case no pronounced peak is observed take the strength corresponding to 20 strain as the unconfined compressive strength.

For φ 0 conditions the shear strength or cohesion of the soil may be taken to be equal to half the unconfined compressive strength. Due to technical difficulties checking out with a credit card may fail. And the suitability of the equipment and facilities used. Unconfined compressive strength tests of cohesive soils quickly provide valuable information for the design of soil embankments and structures.

This test can be performed on intact remolded or reconstituted soil specimens using the strain controlled application of axial loads. In addition in this test method the unconfined compressive strength is taken as the maximum load attained per unit area or the load per unit. Humboldt s unconfined soil testers rimac allow for quick and accurate determination of unconfined compressive strength of cohesive soils in the field or lab. Unconfirmed compressive strength ucs stands for the maximum axial compressive stress that a specimen can bear under zero confining stress.

Astm d 2166 standard test method for unconfined compressive strength of cohesive soil. 5 1 the primary purpose of the unconfined compression test is to quickly obtain a measure of compressive strength for those soils that possess sufficient cohesion to permit testing in the. The unconfined compression test is a laboratory test used to derive the unconfirmed compressive strength ucs of a rock specimen. To order please use net30 if available or call 1 800 544 7220.

The unconfined compressive strength ucs is the maximum axial compressive stress that a right cylindrical sample of soil can withstand under unconfined conditions. Versa loader unconfined compression tester hand operated. Plot σ 1 versus ε and obtain the maximum stress which gives the unconfined compressive strength q u. According to the astm standard the unconfined compressive strength q u is defined as the compressive stress at which an unconfined cylindrical specimen of soil will fail in a simple compression test.

Where p is the compressive force.
