The construction industry in Iran has always been based on the use of durable and affordable materials. Among all building materials, brick is known as the oldest and most reliable material. But not every brick is suitable for every type of construction. Today we are going to investigate the production of three-bladed brick in Daulat Abad, Isfahan. This area is known as the pole of brick production in the country and supplies products with dimensions of 20 x 20 x 10 cm to the whole country. In this article, along with the technical review of this product, we will introduce you to the reliable Sahand brick brand, which is a pioneer in the production of high-quality bricks in this industrial area.

What is a three flower blade brick and why is 10x20x20 dimensions popular?

Three-flower brick, which is also called three-hole brick or Shirazi brick in the term of construction and architecture, is one of the most widely used types of bricks in the implementation of separating blades and internal and external walls of the building. The reason why this product is named "three flowers" is the presence of three large holes in its structure, which give it unique characteristics.

The standard dimensions of this brick are usually 202010 (of course, nominal and actual dimensions may differ by a few millimeters). These dimensions mean that the length and height of the brick is 20 cm and its thickness or width is 10 cm. This thickness of 10 cm has made it the best option for "knife drawing". Blades are walls that do not have a bearing role and are used only to separate spaces.

The production of three-bladed brick in Daulat Abad, Isfahan, with these special dimensions, has caused the speed of building walls to increase greatly. Imagine that a building covers an area of 20 x 20 cm by placing one of these bricks, which multiplies the progress of the work compared to small traditional bricks.

The importance of Daulatabad region of Isfahan in the brick industry

When talking about bricks and pottery, the name of Daulat Abad Isfahan shines like a reliable brand. But why is the production of three-bladed brick in Daulatabad, Isfahan so important, and why do buyers from all over Iran prefer to buy their bricks from this area?

1. Clay quality: The most important factor in brick quality is its soil. Daulat Abad and Barkhar region in Isfahan has very high quality clay mines that are free of harmful salts, excessive lime and destructive impurities. The purity of the soil of this area makes the produced brick not to scale and has a high resistance against pressure.

2. Firing technology: Factories located in Daulatabad, including Sahand brick complex, use modern and tunnel kilns. The uniform baking of brick makes the color of the brick yellow, golden or red, and so-called baked brick.

3. Suitable climate: the dry climate of Isfahan is very suitable for drying raw clay before entering the kiln, which prevents the brick from cracking.

The Sahand Brick Group has been able to take a large share of the country's brick market by taking advantage of this regional potential and combining it with modern engineering knowledge.

The production process of three-bladed brick in Sahand brick factory

To better understand the quality, we have to take a look at the production line. In the Sahand brick factory, the process of producing three-bladed bricks is carried out through precise and controlled steps:

1. Soil preparation

High quality clay is extracted from special mines and transported to the factory. At this stage, the soil is ground and its coarse impurities are separated to obtain a soft and uniform texture. The quality of the incoming soil in Sahand brick is carefully checked by the quality control laboratory.

2. Flower making and molding

The prepared soil is mixed with a certain amount of water to obtain mud with a standard moisture percentage. Then this flower enters the press and extruder. It is at this stage that the general shape of the brick and its holes (three flowers) are created by precise molds. The dimensions of 202010 are determined at this stage. Advanced Sahand brick devices make the edges of the brick completely sharp and smooth and there is no question of crookedness or warping in the final product.

3. to dry

Wet clays cannot go directly into the kiln because they break. They first enter industrial dryers to lose their moisture.

4. Baking in the oven

This is the most sensitive stage. The clays enter the tunnel or Hoffman kilns and are fired at a high temperature (about 900 to 1000 degrees Celsius). The baking time and thermal graph in the Sahand brick factory are set in such a way that the bricks have the highest compressive strength.

Technical characteristics and advantages of three flower bricks 10x20x20

Why should you use three-blade brick for your construction project? The advantages of this product, which is produced in Daulat Abad, Isfahan, by Ajr Sahand Group are:

Heat and sound insulation: the existence of three large holes in the brick body causes air to be trapped inside the wall. Air is one of the best insulators. This feature reduces the heat exchange between the inside and outside of the building and saves energy.
Lightening of the building: The specific weight of these bricks is much less than solid bricks. The use of 2020-2010 three-flower brick reduces the dead load of the building, which is a vital advantage against earthquakes.
Excellent adhesion with mortar: the grooves and holes in the brick allow the cement mortar to penetrate well into the brick texture and create a strong mechanical engagement. This ensures the strength of the wall.
Affordability: compared to cement blocks or foamed clay, the price of three-flowered brick is much more reasonable. Also, due to its large dimensions, the consumption of mortar is also reduced.
Resistance to fire: Brick is a product that was born in fire. Therefore, the walls made with three-flower bricks have a very high resistance to fire.

Applications of three flower bricks (three holes)

Although the name of this product is "blade", its uses are beyond a simple separator. Sahand brick products are used in the following cases:

1. Internal dividing walls: 10 cm thick is ideal for separating rooms.

2. The walls around the elevator and staircase: due to their high resistance and hardness.

3. Shed construction: in the construction of the walls of industrial sheds that require speed of execution and physical resistance.

4. Villa buildings: as a semi-bearing wall in small structures.

Important points in buying three-bladed brick

When you are going to buy a brick with three flower blades, you should pay attention to some key points so that you don't lose your head. The quality of brick production in Daulat Abad, Isfahan is high, but there are different quality levels.

1. Brick color

Quality brick should have a uniform color. If the brick is too dark, it is probably burnt, and if it is too light, it is raw. Sahand bricks have a completely uniform yellow or golden color, which indicates standard baking.

2. bell sound

There is a simple test: gently shake two bricks. They should make a "bell" or ceramic sound. If you hear a muffled sound, it means that the brick is cracked or not baked well. Sahand brick products have a very clear ringing sound due to their high density.

3. Absence of dandruff

Bricks should not turn white after rain. Dandruff indicates too much salt in the soil. The soils used in the Sahand brick factory are washed and processed and will not have the problem of scaling.

4. to be a fool

Brick angles should be 90 degrees. If the brick is crooked, the wall will be crooked and the consumption of plaster and soil to straighten the wall will increase greatly, which will increase your costs.

The impact of gas and transportation prices on the final price of bricks

The finished price of three-bladed brick production in Dolat Abad, Isfahan is a function of energy costs (furnace gas), manpower wages, and machine maintenance costs. However, by optimizing fuel consumption and increasing production efficiency, Sahand Brick Factory has tried to control the increase in prices and deliver a product at a fair price to the consumer.

It should also be noted that for projects that are outside of Isfahan, the cost of transportation is also added to the price of bricks. The geographical location of Daulat Abad in the center of Iran has made access to North-South and East-West transit roads easy and the transportation cost is more balanced than other parts of the country.

Comparison of three-flower brick with blade clay brick

You may ask what is the difference between 202010 three-flower brick and 10 cm clay block?

Clay bricks usually weigh less and have larger dimensions (eg 20x20), but are more fragile. On the other hand, three-blade brick has a much higher compressive strength. If you want to have a wall on which you can later install cabinets or hammer nails without crumbling the wall, three flower bricks are definitely a better choice. In fact, three-flower brick is a combination of the advantages of pressure brick (strength) and clay brick (relative lightness).
