Unconfined Compressive Strength Test Equipment

Unconfined compressive strength tests of cohesive soils quickly provide valuable information for the design of soil embankments and structures.

Unconfined compressive strength test equipment.

For φ 0 conditions the shear strength or cohesion of the soil may be taken to be equal to half the unconfined compressive strength. Plot σ 1 versus ε and obtain the maximum stress which gives the unconfined compressive strength q u. To order please use net30 if available or call 1 800 544 7220. 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.

D2166 d2166m 16 standard test method for unconfined compressive strength of cohesive soil. Where p is the compressive force. Unconfined compressive strength ucs is a quick and simple test to determine the undrained shear strength of cohesive soils. Humboldt s unconfined soil testers rimac allow for quick and accurate determination of unconfined compressive strength of cohesive soils in the field or lab.

The unconfined compressive strength ucs is the maximum axial compressive stress that a right cylindrical sample of soil can withstand under unconfined conditions. The unconfined compression test is a laboratory test used to derive the unconfirmed compressive strength ucs of a rock specimen. 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. Unconfirmed compressive strength ucs stands for the maximum axial compressive stress that a specimen can bear under zero confining stress.

For soils the undrained shear strength su is necessary for the determination of the bearing capacity of foundations dams etc. Versa loader unconfined compression tester hand operated. Due to technical difficulties checking out with a credit card may fail. And the suitability of the equipment and facilities used.

It is also known as the uniaxial compressive strength of a material because the application of compressive stress is only along one axis the. 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. Astm d 2166 standard test method for unconfined compressive strength of cohesive soil. In case no pronounced peak is observed take the strength corresponding to 20 strain as the unconfined compressive strength.

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.
