Granite rocks are igneous rocks, formed by slowly cooling pockets of magma that were trapped beneath the earth's surface. Physically, commercial granites are hard, compact rocks with fine to coarse grains of metamorphic or igneous origin. In terms of properties granite is a unique material. The properties lending uniqueness to granite are:
Granite is widely used as a dimension stone and as flooring tiles in
commercial buildings, monuments as well as private houses. Owing to its
strength, it is also used as foundations for homes in various countries.
With an increase in the number of acid rain in many parts of the world, this
rock has begun to supplant marble as a monument material a sit is much more
durable. Refined or polished granite is also a popular choice for kitchen
counter tops due to its requirement of low maintenance and aesthetic
properties. In such cases, "granite" is a common term for all
igneous rocks with large crystals, and not specifically to those with a
granitic composition. Granite Tiles also finds application for gravestones,
memorials and other artifacts. Engineers generally use polished granite
surfaces to establish a plane of reference, as they are relatively
impervious and inflexible.
