Marble, known in Latin as Marble, is a metamorphic carbonate rock that, due to recrystallization under heat and pressure in the metamorphic period, has a distinct crystalline texture and is mainly composed of calcite and dolomite minerals, or a combination of them. Has been.
Its apparent difference with the travertine stone that can be empirically observed is that if we look back at the stone we find that the marble unlike the travertine has pores and veins.
Some marble rocks have high water absorption due to their calcareous nature. For this reason, they should not be used in places where there is a lot of flooding, such as toilets, toilets, kitchens and bathrooms. It is not weak against natural elements such as rain, cold and heat and weathering like travertine.
Thus, marble stones are crushed if used in places where they are subject to contraction and expansion. Because most marble stones have low strength, they should not be used in busy halls and bridges, as they will wear and tear over time, and should not be used in building facades and in the sun.
Marbles usually have many veins, most of them red or iron oxide or one of its compounds. Changes in export duties and tariffs and state laws have been major drivers of changes in stone production over the past few years. Also, during the year 2005, the consumption of stone has increased due to increased housing construction, especially Mehr housing.
Marbles are also called dolomitic and dolomitic in terms of the amount of magnesium carbonate called calcite marble, magnesite marble or calcite marble. Due to the presence of impurities in bright white to dark colors such as red, cream, brown, pink, black, mustard, green and so on.
The method of cutting marble stones in the mine is by wire cutting. In general, marbles are rocks that are not highly resistant, but some are found to be marble-like in shape and form, but hardly granite or porous, in which case this type of marble is due to its porosity. And the veins are used full.
Formerly putty used to fill the stones with molasses, simka and stone powder but now resin is used. Some marble stones are then glued and resin or epoxy and adhesive to increase the stability of the stone. One of the influencing parameters on the choice of marble is the color variation and for example white marble can be marble. The welders pointed out.
How is marble formed? Marble is a metamorphic rock formed by recrystallization of limestone, so that over time, under pressure and heat, the texture and texture of the metamorphic limestone are recrystallized and reconstituted into a large, coarse and vein calcite. It does.
Where are the marble quarries located? In Iran, many mines have been identified and are being exploited. Of course, there are many marble quarries in our beloved country of Iran that have not yet been identified or have been exploited if identified. Marble is produced and processed in a wide range of colors in Iran
What are the colors and colors of marble? This stone has chains called acetylolite which is like a heartbeat found in stone tissue.
Pure marble is bright and white. The light gray to black color comes from carbonaceous materials. Green dyes are usually produced by chlorite or other silicates. The pink and red color is due to the very scattered particles of hemotite or manganese carbonate and the yellow and cream color due to the presence of limonite.
The Persian marble is silk or emperor silk with alder background.
Marble is a solid stone with a brown background.
Dehydrated marble is an adorable Namin with cream colored background.
The marble of Sabzevar and Kashmar is white in color.
Najaf Abad marble, Golden Black marble, Dehbid black marble and Birjand black marble with black background.
Bavanat marble, Anarak marble and Bejestan marble with red background.
Where is the marble stone used in the building? Some marble rocks have high water absorption due to their calcareous nature. For this reason, they should not be used in places where there is a lot of flooding, such as toilets, toilets, kitchens and bathrooms. It is not weak against natural elements such as rain, cold and heat and weathering like travertine. Thus, marble stones are crushed if used in places where they are subject to contraction and expansion.
Overall, this rock is not a good choice for outdoor spaces unless it is too thick to prevent water penetration and corrosion of the rock, and may cause delays in deep cracks or if the surface is not corroded.
As mentioned earlier, this stone is the most ideal choice for indoor use, and on the other hand, the high color variety and the ability to implement roles on this stone and its subtlety have made it distinct from other stones. Marble can be processed by special mastics and resins, which greatly increase its durability and longevity.
