Granite stone or khara (meaning threshing of large colored grains) is one of the hardest and most abundant building stones that are used in many parts of the world. Granite stone, which is the most abundant natural stone in the earth’s crust after basalt, about 95% of the earth’s surface is made of granite and other igneous stones, is a widely used stone that has various uses from tombstones to construction and sculpture. . But what is granite? How is it formed? And… let’s know more about this stone

Features of granite stone
Granite has many features, including high durability and durability, high strength, resistant to heat, impact and scratches, low water absorption, etc., which makes it suitable for use in different parts of the building. Now we will describe each one in detail:
- Since granite has a high molecular density of hard minerals; It is considered one of the hardest building stones. In this way, cutting machines equipped with special diamonds are used in several stages to cut it
- Granite is very resistant to wear due to its high hardness. But after sub by high-quality polishers, it shows a very beautiful polished surface.
- Granite is strong enough. Therefore, it can bear significant weight.
- If we want to name a negative feature for granite, it is the high weight of the stone. On the other hand, because the stone is solid and non-porous and has a smooth and uniform surface, it does not easily stick to mortar and cement. Therefore, there is a high possibility of the stone separating and falling. Therefore, better options such as Traveton are suggested for stone facades in high-rise buildings. All stonemasons use scope clamps to increase the safety of their work when using granite stones for walls. In this way, the risk of dropping the stone will be reduced.
- Crushed granite (granite aggregates) is also used in road construction, railways, bases and parts that need to be filled.
- The specific weight of granite stone is 2800 kg/m3
Granite is the strongest and hardest building stone. Therefore, it can resist scratches, shocks and wear. In addition, it is resistant to acidic substances. These properties of granite have made it suitable for high-traffic and damage-prone places.
Like any other stone, granite can be damaged over time. For example, strong impacts can cause granite to crack. Of course, it can be repaired. But if it is used correctly, it will not be damaged. For this purpose, you can read the article on repairing building stones with stone glue. In addition, if the granite stone is not sealed well, the possibility of staining increases.
Yes, like any other surface, granite counters also need cleaning and care. In addition, there may be pores on the surface of the stone, where bacteria accumulate. Non-acidic cleaners should also be used to clean granite.
Because granite has very little porosity, it will not stain in most cases. But some granite stones, if they are in contact with moisture for a long time, may become stained and moisture penetrates into it. In addition, for example, the probability of this happening in light granite stones is higher than dark granites, or at least it is more visible. In general, to maintain natural stones, it should always be cleaned immediately if water or any other substance is spilled, if it remains on the stone for a long time, the stone will become stained
Granite is a hard stone. That’s why even a knife blade doesn’t scratch it. It is scratched only if it is scratched with special tools that are special for stone.
Granite’s heat resistance is up to 150 to 200 degrees Celsius. But it is not resistant to temperature changes (heating and cooling) and there is a possibility of cracking
