They consist of a mass of crystals visible to the naked eye and welded together.
Main characteristics of granite rock.
These features make granite pavers perfectly suited for architectural landscaping and pavement applications.
Its three main minerals are feldspar quartz and mica which occur as silvery muscovite or dark biotite or both.
After granite blocks are cut down into granite slabs the slabs are shipped off to fabricators.
Rocks with hardness 1 3 are soft rocks from 3 6 are medium hardness rocks and 6 10 are hard rocks.
