Unconfined Compressive Strength Test Equipment

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.

Unconfined compressive strength test equipment.

The unconfined compression test is a laboratory test used to derive the unconfirmed compressive strength ucs of a rock specimen. Versa loader unconfined compression tester hand operated. An undisturbed or remolded soil sample is loaded in an unconfined condition at a strain rate of 0 5 to 2 per minute until failure. Plot σ 1 versus ε and obtain the maximum stress which gives the unconfined compressive strength q u.

The unconfined compressive strength ucs is the maximum axial compressive stress that a right cylindrical sample of soil can withstand under unconfined conditions. Unconfirmed compressive strength ucs stands for the maximum axial compressive stress that a specimen can bear under zero confining stress. Due to technical difficulties checking out with a credit card may fail. To order please use net30 if available or call 1 800 544 7220.

And the suitability of the equipment and facilities used. Astm d 2166 standard test method for unconfined compressive strength of cohesive soil. Unconfined compressive strength ucs is a quick and simple test to determine the undrained shear strength of cohesive soils. This test can be performed on intact remolded or reconstituted soil specimens using the strain controlled application of axial loads.

It is also known as the uniaxial compressive strength of a material because the application of compressive stress is only along one axis the. 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. For soils the undrained shear strength su is necessary for the determination of the bearing capacity of foundations dams etc. Humboldt s unconfined soil testers rimac allow for quick and accurate determination of unconfined compressive strength of cohesive soils in the field or lab.

Unconfined compressive strength tests of cohesive soils quickly provide valuable information for the design of soil embankments and structures. The unconfined compressive strength ucs is the maximum axial compressive stress that a right cylindrical sample of material can withstand under unconfined conditions the confining stress is zero. Where p is the compressive force. 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.

In case no pronounced peak is observed take the strength corresponding to 20 strain as the unconfined compressive strength.
