Basalt Rock Properties and Uses Science Struck. The rock hardness of basalt is 6 on the Mohs scale, and can be seen through a combination of its compressive strength 100-300 Mpa (Megapascal), its tensile strength 10-30 Mpa, and its shear strength 20-60 Mpa, which denotes that depending on the mineral makeup, basalt rocks fall in the strong very strong category.

The Unconfined Compression Test is a laboratory test used to derive the Unconfirmed Compressive Strength (UCS) of a rock specimen. Unconfirmed Compressive Strength (UCS) stands for the maximum axial compressive stress that a specimen can bear under zero confining stress. Due to the fact that stress is applied along the longitudinal axis, the ...

differentiated by strength rather than geologic origin. Material with a uniaxial (unconfined) compressive strength less than 1.25 MPa is normally taken to be soil (Geological Society of London (GSL) 1977). If, how-ever, an earth material, regardless of origin, is in such a condition that it can be classified by criteria in ASTM

The difference in the unconfined compressive strength between the slow and the rapid rates of factor for the granite was less than l for the basalt, 1.35 for the limestone, 1.52 and for the tuff, 1.74. The compressional wave velocity of rock is affected by increases in both the applied axial stress and confining pressure.

Generally, sedimentary rocks can range from weak to medium (10-80 MPa), and igneous rocks range from medium to very strong (40-320 MPa). The highest unconfined compressive strength observed in a rock is on the order of 400 MPa (e.g. nephritic jade).
Two hard to very hard rock types were investigated that had rough, irregular joints. Basalt has a unconfined compressive strength in the order of 160 MPa and Dolerite 260 MPa. Joint description The joint surfaces of Basalt samples tested were rough, irregular with a JRC of between 6 and 10. The Schmidt rebound number was between 53 and 57.
on undrained (total) shear strength parameters. The undrained shear strength (Su) of cohesive soils (clay and highly plastic silts) can be measured using unconfined compression (UC) tests, unconsolidated undrained (UU) triaxial tests, or consolidated undrained (CU) triaxial tests of undisturbed samples.
Apr 06, 2020 The compressive strength is the maximum load per unit area that the stone can bear without crushing. A higher compressive strength indicates that the stone can withstand a higher crushing load. The required values range from 1,800 psi (12.45 MPa) for marble to 19,000 psi (131 MPa) for granite.
