Methods A and B determine the triaxial .Uniaxial Compression Test AASHTO ASTM -D 2938 Purpose To determine the uniaxial compressive strength of rock (qu = F u = F C). Procedure In this test, cylindrical rock specimens are tested in compression without lateral confinement. The test procedure is simila r to the unconfined compression test for soils and concrete. What is an unconfined compression test? The unconfined compression test, also known as the uniaxial compressive strength test, assesses the unconfined compressive strength (UCS) of a concrete, . Scope1.1 This test method specifies the apparatus, instrumentation, and procedures for determining unconfined compressive strength of intact rock core specimens. 1.2 The values stated in inch-pound units are to be regarded as the standard.

ASTM D2938 – Standard Test Method for Unconfined Compressive Strength of Intact Rock Core Specimens. Scope. ASTM D2938 provides a standardized procedure for determining the unconfined compressive strength of cylindrical rock core specimens. Key points of ASTM D2938: Specimen preparation: a rock core sample is first cut to the desired length .is replaced by the stiffness of the rock mass surrounding the volume of rock of interest. Uniaxial compression tests require a careful test set-up and strict specimen preparation. Requirements for specimen preparation and tes ting are discussed in ASTM D-2938-86 and in the ISRM suggested methods (Bieniawski and Bernede, 1979). End effects can . The unconfined compression test is conventionally performed by applying axial load to a cylindrical specimen with a specific length to diameter ratio. Various arrangements have been developed to perform the unconfined compression tests as indicated in Fig. 1. The short cylindrical specimen represented as type 1 is in direct contact with the .
This test method specifies the apparatus, instrumentation, and procedures for determining unconfined compressive strength of intact rock core specimens. This procedure is identical to ASTM D 2938 except that the cores are tested after cutting without grinding, and neoprene caps are used on the specimen ends. 1.1 This test method covers the determination of the strength of intact rock core specimens in uniaxial compression and confined compression. The tests provide data in determining the strength of rock, namely: the uniaxial strength, shear strengths at varying pressures and varying temperatures, angle of internal friction, (angle of shearing resistance), .The unconfined compression test is by far the most popular method of soil shear testing because it is one of the fastest and cheapest methods of measuring shear strength. The method is used primarily for saturated, cohesive soils recovered from thin-walled sampling tubes. The unconfined compression test is inappropriate for dry sands or crumbly .Standard Test Method for Unconfined Compressive Strength of Intact Rock Core Specimens **ASTM has discontinued this method, the industry-accepted standard test method is now ASTM D7012C.

Such a procedure would be referred as polyaxial or true triaxial test. Moreover, research has shown that the effect of the intermediate stress is minor. The principal stresses applied during a triaxial test are presented in Figure 1. Figure 1: The principal stresses applied in a cylindrical rock sample in triaxial testing (σ1> σ2= σ3)

1.1 This test method covers the determination of the strength of intact rock core specimens in uniaxial compression and confined compression. The tests provide data in determining the strength of rock, namely: the uniaxial strength, shear strengths at varying pressures and varying temperatures, angle of internal friction, (angle of shearing resistance), . 5.2 Method C, uniaxial compressive strength of rock is used in many design formulas and is sometimes used as an index property to select the appropriate excavation technique. Deformation and strength of rock are known to be functions of confining pressure. Method A, triaxial compression test, is commonly used to simulate the stress conditions .Point Load test is an alternate method that can be used to adequately predict the uniaxial compressive strength of a rock material using a portable and simpler equipment. Schmidt Hammer Rebound test is also a technique used for this purpose but, it is admitted that its results are far more variable and affected by testing methods. Test Apparatus
