Unconfined Compressive Strength Test Equipment

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.

Unconfined compressive strength test equipment.

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. This test can be performed on intact remolded or reconstituted soil specimens using the strain controlled application of axial loads. Humboldt s unconfined soil testers rimac allow for quick and accurate determination of unconfined compressive strength of cohesive soils in the field or lab. To order please use net30 if available or call 1 800 544 7220.

The unconfined compression test is a laboratory test used to derive the unconfirmed compressive strength ucs of a rock specimen. For φ 0 conditions the shear strength or cohesion of the soil may be taken to be equal to half the unconfined compressive strength. The undrained shear strength su of clays is commonly determined from an unconfined compression test. It is also known as the uniaxial compressive strength of a material because the application of compressive stress is only along one axis the.

And the suitability of the equipment and facilities used. 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. Versa loader unconfined compression tester hand operated.

Unconfined compressive strength tests of cohesive soils quickly provide valuable information for the design of soil embankments and structures. D2166 d2166m 16 standard test method for unconfined compressive strength of cohesive soil. 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. 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.

Due to technical difficulties checking out with a credit card may fail. The unconfined compressive strength ucs is the maximum axial compressive stress that a right cylindrical sample of soil can withstand under unconfined conditions. For soils the undrained shear strength su is necessary for the determination of the bearing capacity of foundations dams etc. Unconfirmed compressive strength ucs stands for the maximum axial compressive stress that a specimen can bear under zero confining stress.

Where p is the compressive force.
