Research granite rock.

Granite is a common coarse grained hard igneous rock consisting chiefly of quartz orthoclase or microcline and mica. It has sound properties which makes it the most popular building material and it is regarded as the best aggregate for high grade concrete. Granite is composed mainly of quartz and feldspar with minor amounts of mica amphiboles and other minerals. Granite is the most common intrusive rock in earth s continental crust it is familiar as a mottled pink white gray and black ornamental stone.

It has several minerals most prominent ones being quartz and feldspar locked into each other. Granite which makes up 70 80 of earth s crust is an igneous rock formed of interlocking crystals of quartz feldspar mica and other minerals in lesser quantities. Its three main minerals are feldspar quartz and mica which occur as silvery muscovite or dark biotite or both.

Granite rock is made by magma which erupted on the ground surface and then hardened as it cooled down. Granite is also used as a decorative stone it can be of different colours such as grey red or pink. In this paper the variation in rock to rock and concrete to rock shear strength parameters of rock mass consisting of primarily granites is studied among three different geological variants. Granite is a plutonic rock meaning that it forms deep underground.

It is one of the oldest and most durable building products available and will far outlast the building in which it is installed. It is coarse to medium grained.
