3.2.2 shear strength (su)—for unconfined compressive strength test specimens, the shear strength is calculated to be 1⁄2 of the compressive stress at failure, as defined in 3.2.1. 4. Significance and Use 4.1 The primary purpose of the unconfined compression test is to quickly obtain the approximate compressive strength ofD2166 – 06 3.2.1 unconfined compressive strength (qu)—the compressive stress at which an unconfined cylindrical specimen of soil will fail in a simple compression test. In this test method, unconfined compressive strength is taken as the maximum load attained per unit area or the load per unit area at 15 % axial strain, whichever is secured . The unconfined compression strength test is the most popular laboratory test used to determine the compressive strength of soil. The unconfined compression test method is used primarily for saturated, cohesive soils recovered from thin-walled sampling tubes. But the test is inappropriate for dry sands or crumbly clays because these materials would fall apart .The differences between unconfined compression test and confined compression test are sample used for unconfined compression test is not covered by any mould or casing but sample used for confined compression test is enclosed between rigid end-caps inside a thin rubber membrane to seal it from cell water, rubber O-ring are fitted over the .
2.5 Timing device, to indicate the elapsed testing time to the nearest second may be used for establishing the rate of strain. 2.6 Oven, thermostatically controlled with interior of non-corroding material and capable of measuring 110o ± 5o C. 2.7 Weighing Balances, with least count of 0.01g if the specimen weight is less than 100g or least count of 0.1g if the specimen weight is equal .1 Compression Test. A compression test determines behavior of materials under crushing loads. It is conducted in a manner similar to tensile test, except that the force is compressive and the specimen contracts along the direction of the stress The specimen is compressed and deformation at various loads is recorded.This lab report summarizes an unconfined compression test experiment conducted to determine the undrained shear strength of a cohesive soil sample. The test measured the load and deformation of the soil specimen to compute the stress and strain. The undrained shear strength was calculated to be 27.5 kPa, classifying the consistency of the soil as soft. Shear .
The laboratory determination of intact rock strength is accomplished by the following tests: point load index, unconfined compression, triaxial compression, Brazilian test, and direct shear. The uniaxial (or unconfined) compression test provides the general reference value, having a respective analogy with standard tests on concrete cylinders .Unconfined Compressive Strength (UCS) is the load per unit area at which an unconfined cylindrical specimen of soil will fail in the axial compression test. If the axial compression force per unit area has not reached a maximum value even at 20 percent axial strain, the UCS shall be taken as the value obtained at 20 percent axial strain.

UNCONFINED COMPRESSION TEST. Aim: The purpose of this laboratory is to determine the unconfined compressive strength of a cohesive soil sample. We will measure this with the unconfined compression test, which is an unconsolidated undrained (UU or Q-type) test where the late ral confining pressure is equal to zero (atmospheric pressure) [1].The unconfined compression test is usually per-formed on a cylindrical sample with a diameter-to-length ratio of 1:2. The sanple is compressed axially [Figure 12-4(a)] until failure occurs; the shear strength is taken as one-half the compressive strength. In the cone test, a cone with an angle 0 is forced The Unconfined Compression Test is a laboratory procedure for determining the Unconfined Compressive Strength of a rock specimen, clayey soil, and other materials. Laboratory Procedure/ Method Unconfined Compression Test is a variant of an undrained unconsolidated triaxial compression test with a confining cell pressure equal to atmospheric .
