Uses of Gneiss. Every rock is formed under different chemical, physical and biological conditions which results in formation of a wide and distinct group of minerals and hence they find applications in various fields. Rocks are hard, soft, permeable and impermeable. They are of various sizes and shapes, depending on the type of rock.

Gneiss Gneiss is a high grade metamorphic rock, meaning that it has been subjected to higher temperatures and pressures than schist.It is formed by the metamorphosis of granite, or sedimentary rock. Gneiss displays distinct foliation, representing alternating layers composed of different minerals.However, unlike slate and schist, gneiss does not preferentially break along planes of

Many types of stones are available such as basalt, marble, limestone, sandstone, quartzite, travertine, slate, gneiss, laterite, and granite which can be used as construction materials. The stones used for building construction should be hard, durable, tough, and should be free from weathered soft patches of material, cracks, and other defects that are responsible for []

Gneiss Rock Distribution. Gneiss rock is found in many mountainous areas where the natural forces of the Earth have produced the heat and pressure to create the conditions for its formation. The Rocky Mountains of the United States, as well as the Adirondack Mountains are examples of areas where this type of rock is found.

Gneiss (/ ˈ n aɪ s /) is a common and widely distributed type of metamorphic rock.Gneiss is formed by high temperature and high-pressure metamorphic processes acting on formations composed of igneous or sedimentary rocks.Orthogneiss is gneiss derived from igneous rock (such as granite). Paragneiss is gneiss derived from sedimentary rock (such as sandstone).

Gneiss usually does not split along planes of weakness like most other metamorphic rocks. This allows contractors to use gneiss as a crushed stone in road construction, building site preparation, and landscaping projects. Some gneiss is durable enough to perform well as a dimension stone.

Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete.

If you are trying to use a dirt bit to drill in rock, it's not going to work. If you are using a PDC, an air hammer or tri-cone bit, it's going to work." Sounds simple enough but a lot of preparation is required of contractors before that bit touches any part of the ground.
