Physical Properties of Andesite
Physical properties of rocks are used to identify the type of rocks and to discover more about them. There are various physical properties of Andesite like Hardness, Grain Size, Fracture, Streak, Porosity, Luster, Strength etc which defines it. The physical properties of Andesite rock are vital in determining its Andesite Texture and Andesite Uses.
Hardness and Strength of Andesite
The physical properties of Andesite depend on its formation. Physical properties of rocks play an important role in determining its applications in various fields. Rocks are rated on the on the Moh's Hardness Scale which rates the rocks on the scale from 1 to 10. Rocks with hardness 1-3 are soft rocks from 3-6 are medium hardness rocks and 6-10 are hard rocks. The hardness of Andesite is 7 whereas its compressive strength is 225.00 N/mm2. Streak is the color of rock when it is crushed or powdered. The streak of Andesite is white whereas its fracture is uneven. Luster of Andesite is the interaction of light with the surface of Andesite. Luster of Andesite is vitreous. Andesite cleavage is not available. The specific gravity of Andesite is 2.5-2.8. Andesite is opaque in nature whereas its toughness is 1.1. You can also know all the list of rocks in Opaque Rocks, Translucent Rocks and Transparent Rocks.
