Finishing construction stone processing type It is also called stone.
The purpose of finishing can be, in addition to achieving beauty and special effects, the appearance of the physical change of the surface of the stone for its use in conditions and applications. be different Finishing according to the uses of the stone in different ways Various things are done.
· Honed:
· One of the most common surface finishes for Black Granite is honing. This finish is achieved by gradually abrading the stone surface with specialized abrasives until it reaches a completely smooth and polished finish. The highest level of surface smoothness, the most shine, the mirror-like appearance, and the reflection of light give this special polish a unique appeal, making the use of this stone for countertops and exterior building facades very pleasant. Polishing stone surfaces enriches and saturates the colors, resulting in a darker appearance.
· Honed and Colored:
· If designers want to use darker surfaces in honed Black Granite, using a special black color and heat-setting the color in the kiln in several stages allows the color to pe*****te deep into the stone, giving it a darker appearance and making it suitable for areas that require increased contrast. These surfaces create a novel and striking combination when used with light materials or in combination with bright colors.
· Flamed:
· In flaming, part of the stone surface is disintegrated by the heat from a concentrated flame. This process creates a roughness on the surface of the stone, which is called flaming. In addition to its beauty, due to its uneven surface, it has various applications.
· One of the characteristics of Soran Granite is its high flammability compared to other stones.

Green Concrete (Applications and Benefits)
Green concrete, also known as eco-concrete, is considered a revolutionary breakthrough in the history of the concrete industry, first invented in Denmark in 1998.
Green concrete has no relation to the color green! The term "green" here signifies its environmental friendliness. While green concrete closely resembles ordinary concrete, its production requires minimal energy and causes the least harm to the environment. The primary goal of green concrete is to reduce the environmental impacts of concrete.
This type of concrete is produced using waste materials such as slag, power plant waste, recycled concrete, mining waste, glass waste, waste incineration residues, burnt soil, sawdust, combustion ash, and so on. Additionally, with green concrete, all stages of the life cycle of a concrete building, including design, specifications, construction, and maintenance, are taken into account.

Benefits of Green Concrete:
- Reduction of carbon dioxide emissions
- Increased utilization of waste materials
- Reduction of environmental pollution
- Fire and heat resistance
- Good thermal and acid resistance
- Reduction of cement consumption

Applications of Green Concrete:
Below are some applications of eco-concrete:
- Residential buildings
- Office buildings
- Commercial buildings
- Road construction
- Urban volumetric structures (sculptures)

Reducing the weight of the building by using rebar

In the process of implementing different construction projects, different designs and models are used. To reach the final structure, various materials such as rebar and... are used. For this reason, the price of rebar is included in the cost of the project. Even the type of rebar used reduces the weight of the building.

The next important thing is the stability and resistance of the structure. Any design that is implemented for construction must be followed in order to achieve resistance and stability. It is also recommended to use the right materials to reduce the weight and load in different parts of columns, beams and foundations.

The role of rebar in reducing the weight of the structure
Mill plays an important role in all materials used in construction. Observing some special points can save up to 30% in rebar consumption. This ultimately helps to reduce the weight of the structure. But what can help reduce rebar consumption?

One of the methods that can be used is to connect rebar to new methods. In the past, methods such as over lab were used, which were wasted. But methods such as forging and coupler are used. Also, in some cases, it is possible to use prefabricated rebars.

The next point is choosing the right rebar. In order to get the right rebar, you can use the method of constructing experimental devices or using various formulas and software. Finally, choose the best type of rebar according to manufacturer, size, grade, etc.

Gypsum and cement mortar, which is prepared by combining equal amounts of gypsum and white or black cement, is a strong and different mortar. This mortar is a widely used combination in different stages of the construction industry, which makes the construction progress better. In the preparation of this mortar, they usually use a combination of white cement and plaster, although sometimes dark cement is also used for various purposes.

Features of cement mortar and plaster
Adding cement to plaster and preparing plaster and cement mortar increases the strength and adhesion of the mortar and improves its durability. In fact, this mortar does not have the weak points of gypsum mortar and improves its strength and efficiency. In this way, without using such a material and only by adding white cement to plaster, the adhesion and durability of plaster mortar increases significantly.

Another feature of this combination is resistance to wind, rain, pressure and temperature changes. Thus, with the passage of time, it maintains its properties and does not change much. Plaster and cement mortar is also easy to use with basic tools and is easily transferred to the desired surface. This mortar also dries relatively quickly and becomes stronger over time.

Application of plaster and cement mortar
The high resistance of plaster and cement mortar against heat and cold, rain and snow has led to its acceptance and use in building facades. So that the mixture of plaster and cement is a durable, uniform and of course cheap choice for the facade. This mixture is also widely used in interior matters, and it is considered a good choice for filling low and high places, seams and cracks. The applications of plaster and cement in the building include the following:

- Installing and gluing stone, tile and ceramic on different surfaces and more of the facade of the building
- Widely used in filling and gluing ready and prefabricated plasterboards
- Grout of the interior walls of the building
- Widely used for building flooring
- Use as a base for other flooring and wall coverings
- Underlaying parts that are prone to dandruff.
