maximum compressive strength of basalt rock
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: 100300 Mpa (Megapascal), its tensile strength: 1030 Mpa, and its shear strength: 2060 Mpa, which denotes that depending on the mineral makeup, basalt rocks fall in the strong very strong categoryRocks are rated on the on the Moh's Hardness Scale which rates the rocks on the scale from 1 to 10 Rocks with hardness 13 are soft rocks from 36 are medium hardness rocks and 610 are hard rocks The hardness of Basalt is 6 whereas its compressive strength is 3740 N/mm 2 Streak is the color of rock when it is crushed or powderedProperties of Basalt Physical Thermal Compare RocksNov 01, 2020 For basalt rocks, Malik et al 12 investigated Deccan basalt rock and found the dynamic compressive strength between about 170 MPa and 260 MPa at a strain rate of about 400/s to 1600/s Lindholm et al 13 found a much lower dynamic strength of about 110 MPa to 125 MPa at a strain rate of about 600/s and 1100/s for Dresser basalt rockDynamic compressive properties of Kalgoorlie basalt rock
