cohesive strength of basalt rock
8. STRENGTH OF SOILS AND ROCKS
Rock strength has been found to be size dependent because of the cracks and fissures that are often present in the material. This is illustrated from the results of tests on three rock types in Fig. 8.2. The size dependancy is also found to exist for stiff fissured clays, as illustrated in Fig. 8.3 for London clay. Rocks with parallel arrangements of minerals or joints have been found to be

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.
