Granite is an igneous rock which forms from cooling & hardening of magma below Earth's surface. Granite is composed mainly of quartz, feldspar, mica, and other minerals. depending on their mineralogy Granites can be predominantly white, pink, or grey in color. Granite is a very hard stone and resistant to damage. The average density of granite is 2.65 g/cm3. Granite compressive strength is between 100 and 300 MPa & shows very low porosity, high resistance against heat & a water absorption which is usually under 1%. durability against heat and cold makes Granite a practical choice for places in which strength is of utmost importance such as, street pavements, sidewalks & docks as well as indoors spaces which are exposed to higher abrasiveness. These advantages make it a proper choice for official, commercial & educational buildings as well as public-use areas. Due to its low water absorption & slurry adhesion, using fixing tools for installation is necessary to avoid slippery.
