Common Types of Stones Used for building

The article will introduce the properties and uses of the more common stones used for building: granite, marble,sandstone, slate,Basalt and Trap, Laterite,Gneiss,Quartzite .

Granite

Granites are igneous rocks. The colour varies from light gray to pink. The structure is crystalline, fine to coarse grained. They take polish well. They are hard durable. Specific gravity is from 2.6 to 2.7 and compressive strength is 100 to 250 N/mm2. They are used primarily for bridge piers, river walls, and for dams. They are used as kerbs and pedestals. The use of granite for monumental and institutional buildings is common. Polished granites are used as table tops, cladding for columns and wall. They are used as coarse aggregates in concrete.

Sand stone

These are sedimentary rocks, and hence stratified. They consist of quartz and feldspar. They are found in various colours like white, grey, red, buff, brown, yellow and even dark gray. The specific gravity varies from 1.85 to 2.7 and compressive strength varies from 20 to 170 N/mm2. Its porosity varies from 5 to 25 per cent. Weathering of rocks renders it unsuitable as building stone. It is desirable to use sand stones with silica cement for heavy structures, if necessary. They are used for masonry work, for dams, bridge piers and river walls.

Basalt and Trap

The structure is medium to fine grained and compact. Their colour varies from dark gray to black. Fractures and joints are common. Their weight varies from 18 kN/m3 to 29 kN/m3. The compressive strength varies from 200 to 350 N/mm2. These are igneous rocks. They are used as road metals, aggregates for concrete. They are also used for rubble masonry works for bridge piers, river walls and dams. They are used as pavement.

Slate

These are metamorphic rocks. They are composed of quartz, mica and clay minerals. The structure is fine grained. They split along the planes of original bedding easily. The colour varies from dark gray, greenish gray, purple gray to black. The specific gravity is 2.6 to 2.7. Compressive strength varies from 100 to 200 N/mm2. They are used as roofing tiles, slabs, pavements etc.

Laterite

It is a metamorphic rock. It is having porous and sponges structure. It contains high percentage of iron oxide. Its colour may be brownish, red, yellow, brown and grey. Its specific gravity is 1.85 and compressive strength varies from 1.9 to 2.3 N/mm2. It can be easily quarried in blocks. With seasoning it gains strength. When used as building stone, its outer surface should be plastered.

Marble

This is a metamorphic rock. It can take good polish. It is available in different pleasing colours like white and pink. Its specific gravity is 2.65 and compressive strength is 70–75 N/mm2. It is used for facing and ornamental works. It is used for columns, flooring, steps etc.

Gneiss

It is a metamorphic rock. It is having fine to coarse grains. Alternative dark and white bands are common. Light grey, pink, purple, greenish gray and dark grey coloured varieties are available. These stones are not preferred because of deleterious constituents present in it. They may be used in minor constructions. However hard varieties may be used for buildings. The specific gravity varies from 2.5 to 3.0 and crushing strength varies from 50 to 200 N/mm2.

Quartzite

Quartzites are metamorphic rocks. The structure is fine to coarse grained and often granular and branded. They are available in different colours like white, gray, yellowish. Quartz is the chief constituent with feldspar and mica in small quantities. The specific gravity varies from 2.55 to2.65. Crushing strength varies from 50 to 300 N/mm2. They are used as building blocks and slabs. Theyare also used as aggregates for concrete.

Choosing Natural Stone Tile-Granite

Origin: Granite is an igenous rock, which means that it is the result of molten rock that has cooled in subterranean pockets until it’s solid. Colors of granite depend on the sundry minerals trapped and suspended inside the molten rock during this process. It’s these sundry materials that give granite an incredible density and stability. Granite is one of the hardest materials on earth.

Appearance: The color range of granite is incredibly varied, from absolute black to white leopard, to golden yellow, and beyond. Indeed, granite offers subtle blues, greens, and grays that are commonly popular selections for all kinds of surfaces in residential and commercial settings. Thanks to high quartz content in all granite, the speckle patterns makes granite in general a distinctive stone type.

Effects: Granite tile is known for its no-nonsense, professional air. As such, it’s been used in hallways and foyers all over the world as flooring and as wall cladding to make a good first impression in commercial towers and hotels. It also creates a look of elegance in residential settings, too.

How to use granite: Floor tile, wall cladding, tile-based countertops, bathroom vanities, cutting boards, coasters.

Advantages: high-end professional look, supreme hardness

Challenges: Granite is very hard, so it’s difficult to cut without experience and the right equipment. You may have to get special tools to cut it, or (better yet) get a professional if you plan on-site cutting. It’s also pretty heavy, which is another reason to get professional advice, and to make room in your budget for a professional installation.

Stone Products

Marble:
Pressurized limestone underneath the Earth’s crust allows marble to form. Marble is a lot softer than its counterparts and have to be mined with care.Impurities in the limestone during this process give marble its unique patterns and colors depending on the infringing minerals. Being highly resistant to heat and erosion, it was used by the ancient Greeks and Iranians for their buildings and statues. Marble is an excellent choice for the classic natural look for your home

Granite:
Naturally occurring igneous rock formed by magma. It is normally composed of quartz, feldspar and other dark minerals.Granite is extremely hard and is resistant to weathering which allows it to be an excellent choice for building aesthetics. However, its dense grain patterns make it susceptible to staining. But there are sealants readily available to inhibit the stain long enough for one to clean it up. Depending on the location the magma flows, the magma metamorphisms are what give granite its unique colors and amazing textures. Granite is the most versatile natural stone to be used in your home.

Atificial stone:
Quartz composites offer a lot of advantages over other natural stones and are a great  material to use in places of high volume or stress and are no less beautiful than natural stones. Being extremely hard, its virtually resistant to impact, scratches and cracks. Its consistent patterns and colors make join lines nearly invisible.It is also resistant to temperatures up to 300 degrees Fahrenheit. This material is non-porous and non-absorbent which allows it to be immune to stains.

What is the difference between granite and quartz

We are always getting asked What is the difference between granite and quartz base surface countertops.look at difference as follows:

Looks
Because granite is a natural product, there are no two identical stones. If you do decide to go with granite, we suggest that you always look at the whole slab beforehand and make sure you ask to choose the one you like. There are endless options of colour, pattern, and variations. Going with granite offers you natural andextremely unique look that only you will have.granite sample display

Quartz base surfaces are more consistent in colour, patterns, and variations. Because the factory makes them, you know that one slab will look like the other. However,with the growing popularity of natural stones, quartz base surface manufacturers are beginning to expand their selections by offering slabs and tiles that  natural stone.Quartz Stone display

One of the most important differences between the two is that quartz base surfaces can be found in any colour you want. Because of their colours and lack of natural movement, these slabs are perfect for modern and ultra modern looks.
While quartz base surfaces can be found in any colour, granite is limited to what we have been given by Mother Nature. For example, the White Quartz WOMAG stocks, is completely white without any movement or discolouration. This is extremely rare and almost  impossible to find in any of our white granites.

While quartz base surfaces can easily be ordered by catalogue, granite cannot as it is found naturally in nature. However, WOMAG's natural stone collection is just as varied as its quartz base surfaces. What makes WOMAG stand out from all its competitors is that our buying team travels to the far corners of the earth looking for the most unique and beautiful stones, bringing back a huge range of colours and patterns.

Strength
In essence, granite and quartz base surfaces are both equals in terms of longevity. Both are resistant to staining, chipping, and cracking.
Because granite is found naturally, WOMAG ensures its longevity by sealing it. While quartz base surfaces are made by humans, they already add a "sealer" to their product.

Maintenance
Both are extremely easy to clean and care for. We recommend using mild soaps with warm water to wash off any spilled liquids or just cleaning in general.

Cost
The cost of granite and quartz base surfaces really depends on the slab you are looking for. There is some granite that costs less than quartz base surfaces and vice versa.

In conclusion, the better of the two is your personal preference. One customer may  appreciate the natural veining and different movement found in granite slabs while another prefers the consistency that comes with quartz base surfaces. Both granite and quartz base surfaces will increase the beauty of your home as well as the value.

Choosing to upgrade your countertops to a quartz base surface or granite will only benefit you in the long run.

Granite is a natural stone and quartz base surfaces are manufactured.
Granite is formed deep in the Earth's crust from hot molten rock, otherwise known as magma. This magma undergoes pressure from the intense heat and rises through the Earth's crust through the cracks and crevasses of the earth. As the boiling magma slowly cools down, it forms Granite. Granite is then quarried and cut into slabs and tiles for your home or business.

Quartz base surfaces on the other hand are manufactured in a factory using a mixture of high quality quartz, special adhesives, and pigments. Quartz base surface countertops are also called engineered counter tops or man made countertops. display stand for quartz stone
