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.

basalt 39 s compressive strength

Rock mass strength is defined by three parameters including unconfined compressive strength of intact basalt and two others related to the degree of fracturing of the material. Experimental results for elevated temperature extend the applicability of these parameters to the near‐surface environment of
