Uniaxial compressive strength (UCS) and Brazilian tensile strength (BTS) of the rock material are important engineering parameters in designing of surface and underground structures in rocks. Assessment of the Hoek–Brown criterion shows that the uniaxial compressive strength increases with increasing loading rate, and the parameter m appears unaffected by .

tension, compression or torsion test. A material may exhibit di erent properties depending on the type of load applied. In this test, the applied load is compressive in nature. When a material undergoes uniaxial compression, the atoms or molecules tend to come close together in the direction of the applied force. 1.3 Learning Outcomes At the end of the laboratory activities, students would be able to: i. Identify the correct apparatus and procedure to conduct the uniaxial compressive strength ii. Analyse test data and present . The uniaxial or unconfined compressive strength (UCS) test is by far the most common laboratory test undertaken for rock mechanics studies, that is assuming one accepts the point load index test . The uniaxial compressive strength (UCS) of rock is one of the key parameters determining the mechanical behavior and failure characteristics of rocks under loading/unloading conditions (Hajiabdolmajid and Kaiser, 2003; Yagiz, 2008; Yarali and Kahraman, 2011; Tan et al., 2016; Xia et al., 2019; Meng et al., 2020; Zhang et al., 2021a).The UCS is also a vital .

where σ is the uniaxial compressive strength in MPa, P is the force failure in kN, and A is the sample area in mm 2.. Axial and radial deformation (ε ax i ε rad) are terms that refer to the changes in the height and diameter of the sample due to the applied load, and these are measured using a displacement sensor during the test. Figure 2. shows the deformation . In this partially open laboratory activity, the students are required to carry out tests to determine the uniaxial compressive strength of rocks. OBJECTIVE The objective of the laboratory test is to measure the uniaxial compressive strength of rock sample in the form of specimen of regular geometry. METHODOLOGY 1.

This document reports on a laboratory experiment to test the compressive strength of concrete cubes cured under different conditions. The objective was to achieve at least 75% of the target strength of 25 MPa for 7-day cured concrete cubes. Three 150mm cubes were tested - two cured in water and one cured dry. The compressive strength of the cubes ranged from 10.78 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.

(1) The document describes procedures for testing the uniaxial compressive strength of rock samples. Cylindrical rock specimens between 2.5-3 times higher than their diameter are tested. (2) A loading machine applies axial load at a rate of 0.5-1 MPa/s until failure within 5-10 minutes. (3) The maximum load at failure is recorded and divided by the cross-sectional area to .The uniaxial monotonic compression test is the first type of test within this program. The specimens were produced in the Road and Railway Research Laboratory by means of a gyrator. Cylindrical specimens of 100 mm high and 50 mm in diameter were drilled horizontally from gyratory cores of 85 mm high and 150 mm diameter.σ – φ c=2 φ 1 . c cos. sin (3.3) where c and ϕ are the cohesion and friction angles of the rock, respectively.. 3.3.2 Test procedure. The test is quite simple and the interpretation is fairly straightforward. A cylindrical core of at least 54 mm in diameter (NX core) and length/1.4 Theoretical Background Most characterization and classification of rock is by uniaxial compressive strength (UCS). The strength of rock is the ability to sustain maximum compressive load, before it fails. Load at failure is considered when more than 50 percent of sample by volume has broken. Uniaxial compressive strength is determining for length to .

The shear strength of the specimen is calculated as half of the unconfined compressive strength: Undefined compression strength: 175/m² Shear strength: 87/m² Lab Data Sheet: 1 0 0 33 0 28. 1 0 0 34 0 29.The Uniaxial Compression Test, or also uniaxial test or simply uniaxial test, is a test that allows to characterize the strength of a rock and is standardized according to the ASTM-D7012 standard. The uniaxial compression test complies with test methods C and D of the ASTM-D7012 standard; it can in fact be conducted in two ways:

Prediction of elastic mechanical properties such as uniaxial compressive strength (UCS) and static Young’s modulus (E s) is one of the main purposes of studies in geological, geotechnical, geophysical, petroleum, and rock engineering projects. The UCS test is applied to determine them. However, this test is destructive, expensive, time-consuming, and .

Compression tests are used for subscale testing and characterizing the mechanical behavior of anisotropic materials. This article discusses the characteristics of deformation during axial compression testing, including deformation modes, compressive properties, and compression-test deformation mechanics. Uniaxial compressive strength (UCS) is one of the crucial parameters controlling the strength of rock masses (Hu et al. 2012).A reliable and direct measurement of this parameter in the laboratory requires well-prepared samples and certified testing apparatus (Heidari et al. 2012).As an indirect method, index tests have been widely used to estimate the UCS of rock, . Literature Review 1.1 Uniaxial tensile testing Uniaxial tensile test is known as a basic and universal engineering test to achieve material parameters such as ultimate strength, yield strength .

Natural Resources Canada (NRCan) through the CANMET Mining and Mineral Sciences Laboratories

One of the parameters which affect the uniaxial compressive strength (UCS) of rock materials is the length to diameter ratio (L/D) of test cores. ASTM recommends a ratio of between 2 and 2.5, and ISRM suggests 2.5–3:1. Research has shown that high UCS values are obtained for L/D ratios <2, a very slight difference in values between 2 and 2.5, and they .Measuring the compressive strength of a steel drum. In mechanics, compressive strength (or compression strength) is the capacity of a material or structure to withstand loads tending to reduce size (compression).It is opposed to tensile strength which withstands loads tending to elongate, resisting tension (being pulled apart). In the study of strength of materials, .
