Limestone, which is also confused with tramite, is a calcareous and sedimentary stone. Limestone is a building stone used for interior decoration. Limestone, if covered with nano materials, will be able to compete with white travertine stones. Limestone is one of the first stones used by humans. This rock has been called the youngest sedimentary rock because its formation time is shorter compared to other sedimentary rocks
How to form limestone
Limestone is a calcareous and sedimentary rock and it is formed from the mineral cleist. This stone is lightweight and does not weigh much compared to marble and marble stones
Argonite, dolomite, quartz, feldspar, hematite and limonite are other materials that contribute to the formation of this stone. Skeletons called fossils can be seen in the structure of these stones. These stones are created in marine environments, especially shallow seas, where the temperature, concentration and salinity of sea water affect this stone
Characteristics of limestone
Limestone has a smooth surface.
The absorption of water in limestone is very high, and according to the progress of science, the limestone stones are nanosized, which has made this stone resistant to water absorption.
Limestones have a bright color that creates a pleasant atmosphere when used in different parts of the building.
Limestones do not have good wear and erosion resistance.
Due to its low strength, it may be easily crushed.
Limestone is crushed by hitting sharp objects

Limestone stones are not a suitable choice for exterior facades of buildings and it is better to use this stone in open spaces. Another problem with limestone is the high water absorption and low erosion resistance of this stone, which has caused this stone to not be used in places where traffic is high and there is a lot of flooding
Now let's look at some of the uses of this stone:
Flooring and stairs
The floor of the parking lot and its walls
Staircase walls
The frame around the elevator
Around the windows
The walls of the stairs
Decorations
Explicit construction
statues
Advantages and disadvantages of limestone
Among the benefits of limestone, the following can be mentioned:
Uniform surface is the most important advantage of limestone. The use of uniform and smooth stone in the facade of the building makes the space twice as beautiful.
The reasonable price of limestone is another advantage of this stone. It is very economical to use this stone in large construction projects.
The big price difference with travertine stone and its easier cutting is one of the advantages of limestone.
The lighter weight of limestone compared to travertine is one of the positive features of this stone.
Ensuring the health of the stone in terms of not having cracks and streaks is another advantage of limestone.
Another advantage of this stone is its height and height
Limestone mines
The cities of Islamabad Kermanshah, Semiram Isfahan and Mahmudabad Isfahan are among the most important limestone mining mines.
Also, the cities of Mahabad, Bozhan, Gohra, Bukan and Maroodasht in Fars province are among the other mines that extract limestone.
Types of limestone
Marvdasht Limestone
This stone is mined in Morodasht city, which is located in the north of Shiraz city. Marvdasht limestone has a white background. The surface of this stone is very smooth and uniform. The use of this stone is in the interior of the building, the wall of the stairs and the parking lot, stone volumes and decorative stone artifacts.
Mahabad Limestone
Mahabad Limestone is extracted in Mahabad city of West Azarbaijan province. This stone has a colored background. The application of this stone is in the internal walls and facade of the building, especially the sub-parts of the building, because this stone has no resistance against factors such as weathering and sunlight.
Gemstone Limestone
Gemstone limestone is extracted in the mines of Khorram Abad, which is located in Lorestan province.The background color of this stone is light cream-white, and brown streaks can be seen in the weaker varieties of this stone. This stone is also known and used in Europe and America. The application of this stone is in the inner wall of the building, interior decoration, stairs and corridors.
Buchan Limestone
Bukan Limestone is mined in Bukan city, which is located in West Azarbaijan province, and has a white and cream background, and yellow grains and lines can be seen on their surface. This stone is used in the interior and exterior of the building.Bukan Limestone is also used in making stone artefacts such as Sarahi and statue
Kermanshah limestone
Kermanshah Limestone, which is similar to Islamabad Limestone and Vanak Limestone, is mined in Kermanshah province and has a light cream-white background. This stone is used in the interior walls of buildings that are not exposed to moistur!
