Andesite Properties

Andesite properties are essential when it comes to identification of rocks. The study of properties of Andesite rock is done by Mineralogists to determine the identity of rock. Some of the properties of Andesite include: Hardness, Color, Fracture, Luster, Compressive Strength etc. Andesite is Very fine-grained. As compared to other rocks, Andesite is more porous and its density is 2.11-2.36 g/cm3. Get to know more about physical properties of Andesite and thermal properties of Andesite.

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.

Thermal properties of Andesite

Check out more about What Is Andesite and its thermal properties. Thermal properties of Andesite play an important role in geology. Specific heat capacity, resistance offered by the rock to heat, water, pressure etc. are some of the thermal properties of Andesite.

Specific Heat Capacity of Andesite

Specific heat capacity is defined as the heat capacity per unit mass of rock. Specific heat capacity or specific heat is one of the important properties of Andesite. The specific heat capacity of Andesite is 2.39 kJ/Kg K. Properties of Andesite also include resistance of Andesite to heat, water, pressure, impact etc. It helps in determining the parameters to which Andesite offers resistance. If we talk about Andesite resistance, Andesite is heat resistant, pressure resistant, wear resistant.
