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.
