Basalt rock properties and uses science struckThe 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.

Part of the columbia river basalt group reidel et alExtensive documentation of the igneous rock and with its uniaxial compressive strength and deformabilityHowever for weathered basalt tugrul and gurpinar 1997 and gu et al2008 have studied the geotechnical properties of the the basalt rock.
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.
Rocks with hardness 1-3 are soft rocks from 3-6 are medium hardness rocks and 6-10 are hard rocksThe hardness of basalt is 6 whereas its compressive strength is 37Streak is the color of rock when it is crushed or powderedThe streak of basalt is white to grey whereas its fracture is conchoidalLuster of basalt is the interaction.
Strength is maximum when 2 fiber usedAbout 40 to 50 increase in strength is observedAs seen from table 3 the 28 days average compressive strength is maximum when 2 fibers are usedAbout 83 amp; 92 increase in compressive strength than the design strength when the basalt fibers are introduce in concrete.
