Granite is known for its exquisiteness and forte. India produces more than 100 colours of toughest and elegant Granite. There are two main categories of granite in India namely as South Indian Granite and North Indian Granite. Different quarries of granite are indifferent parts of India and offer variety in colour and patterns. Granite quarries are mostly located in states of Rajasthan, Andhra Pradesh, Karnataka, Tamilnadu and Telangana.

All Indian Granite Colours are ideal for flooring, wall cladding and counter tops applications. India is known for its top-quality granites worldwide, we at ASN overseas OPC Pvt Ltd offer diverse colours, sizes and finish at a reasonable price and competitive delivery timelines for our customer’s complete satisfaction.

Physical properties of Granite

Granite is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. The word “granite” comes from the Latin granum, a grain, in reference to the coarse-grained structure of such a crystalline rock. The term granite also applies to a group of intrusive igneous rocks with similar textures and slight variations on composition and origin. These rocks mainly consist of feldspar, quartz, mica, and amphibole minerals, which form interlocking, somewhat equigranular matrix of feldspar and quartz with scattered darker biotite mica and amphibole (often hornblende) peppering the lighter colour minerals. Granites can be predominantly white, pink, or grey in colour, depending on their mineralogy. Granite is an igneous rock with at least 20% quartz and up to 65% alkali feldspar by volume

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, melting temperature of dry granite at ambient pressure is or 1215–1260 °C (2219–2300 °F); it is strongly reduced in the presence of water, down to 650 °C at a few kBar pressure. Granite has poor primary permeability, but strong secondary permeability.

Chemical properties of Granite

Granite is a hard-igneous rock having a coarse-grained surface, chiefly composed of four minerals viz., quartz, alkali feldspar, plagioclase feldspar, and hornblende. These minerals provide the different colours to the granite that it possesses. Granite being an igneous rock, is formed from the process of magma cooling.

This magma, which cools far below the earth’s surface at a slow and steady rate, results in the expansion of the minerals to a level that they can be conveniently seen with naked eyes. An important thing about granite is that it is not a homogeneous rock, thus its chemical properties vary according to its location. The worldwide standard of the average proportion of different chemical components that are present in granite is given below.
