At the same time as testing UCS, the tester can also measure axial and lateral . Rock engineering tasks like tunnelling, dam and building construction, and rock slope stability rely heavily on properly estimating the rock’s uniaxial compressive strength (UCS), a crucial rock geomechanical characteristic. As high-quality specimen are not always possible, scientists often estimate UCS indirectly. The primary objective of this paper is to . The uniaxial compressive strength (UCS) of rocks is a vital geomechanical parameter widely used for rock mass classification, stability analysis, and engineering design in rock engineering.
When a uniaxial compressive load is applied to an object it will become shorter and spread laterally so its original cross sectional area . Compressive strength test of concrete in UTM. . In addition to simple compression testing, testing standards such as ASTM C39, ASTM C109, ASTM C469, ASTM C1609 are among the test methods that can be . Scope1.1 This test method covers the measurement of the deformability and strength of large in situ specimens of weak rock by a uniaxial - compressive test. The test results take into account the effect of both intact material behavior and the behavior ofIt also reviews the factors that influence the generation of test data for tests conducted in accordance with the ASTM E 9 and the capabilities of conventional universal testing machines for compression testing. .

The Protodyakonov model or ASTM model can be used as a verification method for the results of a uniaxial compressive strength test of coal–rock combination. The elastic modulus of the . The uniaxial compressive strength (UCS) test is crucial in determining the strength and stiffness behavior of intact rock and is frequently utilized by industry to determine project site characteristics. A fundamental procedure of UCS testing is strain response measurement. Conventionally, discrete strain measuring devices such as extensometers .
Introduction. The Brazilian Test is a laboratory test conducted in rock mechanics to indirectly determine the tensile strength of rocks. The tensile strength of rock materials is an important parameter in designing a geotechnical project since it is significantly lower than the rocks’ compressive strength.

Abstract. Uniaxial tensile and compressive strength were determined for a granite, a marble, and a sandstone. There was no statistically detectable difference between the strength values of large and small samples, although the volume ratio of the samples was 20 or more. Further, strain gage measurements taken during the compression tests on the granite revealed strength .
