### Properties of Basalt | Physical | Thermal - Compare Rocks

The hardness of Basalt is 6 whereas its compressive strength is 37.40 N/mm 2. Streak is the color of rock when it is crushed or powdered. Streak is the color of rock when it is crushed or powdered. The streak of Basalt is white to grey whereas its fracture is conchoidal.

### Basalt Rock Properties and Uses - ScienceStruck

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.

Values of tensile and cohesive strength for the basaltic rock mass are approximately one to two orders of magnitude lower than corresponding values for intact basalt. Temperatures comparable to those at the Venus surface may slightly increase the deformation modulus but …

### Compressive Strength - an overview | ScienceDirect Topics

The major principal stress is horizontal with a magnitude of 3.4 MPa, and the compressive strength of the rock types is 53 MPa for the shale and 71 MPa for the basalt. The strength/stress ratio for these two cases is then 53/3.4 = 15.6 and 71/3.4 = 20.9, respectively, and so for both of them the stress reduction factor is 1.0.

### Estimating uniaxial compressive strength of rocks using ...

Several mechanical properties, including uniaxial compressive strength (UCS), have become widely accepted parameters for rock design projects (Baskerville, 1987). The Upper Miocene ignimbrite of Erciyes outcrops is described as brown, black, yellow and gray; and the Yavuzeli basalt is mainly of Middle Upper Miocene (Table 1).

### STRENGTH PROPERTIES OF ROCKS AND ROCK MASSES 1 ...

if a rock mass is cut by directional joint sets , the rock mass strength is anisotropic. Rock mass strength is scale dependent and varies with the volume of rock under consideration. The modes of failure of intact rock are multiple. Rock can fail in tension, compression or shear.
