Granite

Project Details

Details: Granite is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Granites can be predominantly white, pink, or gray in color, depending on their mineralogy.
Granite is nearly always massive (lacking any internal structures), hard and tough, and therefore it has gained widespread use throughout human history, and more recently as a construction stone. The average density of granite is between 2.65 and 2.75 g/cm3 (165.4 – 171.7 lb/ft3), its compressive strength usually lies above 200 MPa.
The melting temperature of dry granite at ambient pressure is 1215–1260 °C (2219–2300 °F);[5] it is strongly reduced in the presence of water, down to 650 °C at a few kBar pressure.
