• what is the compressive strength of basalt

    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.Dynamic compressive properties of Kalgoorlie basalt rock,2020-11-1 · In this study, the basalt rock extracted from the Kalgoorlie region of Western Australia is intensively studied on its compressive properties under both static and dynamic loads covering strain rate between 2.22 × 10-6 /s to 408/s.
