compressive strength of basalt rocks

compressive strength of basalt rocks

Rocks are rated on the on the Mohs 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 Nmm 2 Streak is the color of rock when it is crushed or powdered The
