Which is better, blue brick building or red brick building? What s the difference?

Which is better, a blue brick building or a red brick building, depends on the needs of the building. Green bricks are generally used in ancient buildings or antique buildings, and the cost is slightly higher. Red bricks are suitable for most construction uses, and the corresponding cost is slightly lower.

Red bricks are generally made of loess layer, according to crushing, mixed with water, made and formed by human resources or machinery and equipment, after drying, put into the brick kiln, burned through the fire and then stop the fire, and wait for the natural refrigeration of the bricks. Because the brick kiln is open to the pores, so the steam in the kiln is relatively smooth, O2 is sufficient, and the copper content in the billet is oxidized into ferric oxide by the air, so its color is red. The production process of red bricks is simpler than that of green bricks, and today's brick factories are all automated mechanical production and processing, and the production efficiency is also very high, which is widely used.

Red bricks have poor compressive strength. Because the sand of the red brick is the yellow mud of the peak. The yellow mud is relatively uneven, and the viscosity and density are not enough.

After centralized incineration, the internal structure causes bubble-like pores, resulting in poor function of bearing capacity impact male sexual function. Before everyone builds a house in the countryside before the ashes, just take a wooden stick and knock it a few times, and the surface layer will be shattered. In ancient times, there was a high probability of a duel at any time, whether it was a city wall or an important administrative unit, if red bricks were used, it was easy to be attacked by the enemy.

Poor anti-corrosion properties. If the surface of the red brick is not coated with concrete, it will become soft after sun and rain, and it will end like a slice of bread with slag. If red bricks were used in ancient times, it is very likely that we will not be able to see a lot of history and culture.

The soil layer used for green bricks is prone to low-lying clay soils, and most of them are obtained from agricultural land. In modern times, in order to better maintain the field, it is not allowed to mine and burn in the field. Its production process is similar to that of red bricks, but with a different refrigeration production process.

When the bricks are burned close to each other, they are cooled by pouring cold water, and then put them into the kiln after pouring, and dry them gently with the kiln. This whole process is somewhat similar to the heat treatment process of quenching, according to which the brick becomes very strong and hard. During the rapid cooling process of bricks, the bright red ** organic compounds in the bricks are converted into light green cheap organic compounds, thus creating the emerald green color that everyone sees.

Green bricks have high strength and strong corrosion resistance. In the historical history and culture of the historical buildings that everyone sees today, you can appreciate the solidity of the historical accumulation of green bricks. After thousands of years of wind and rain, it still stands majestically.

Of course, it is a red brick building, the difference is that the hardness of the red brick building is relatively high, and most of them are used to build royalty, while the blue brick building is used by ordinary people.

Is it better to use red bricks or green bricks for building houses in rural areas? What's the difference?

1. Material comparison.

Red bricks: clay firing with low purity, the clay contains iron, and when it is completely oxidized during the firing process, ferric oxide is generated and red;

Green bricks: When the clay is fired, water is added to cool it during the firing process, so that the iron in the clay is not completely oxidized and turns cyan.

Second, the advantages of comparison.

Red Brick: 1Durability, certain thermal insulation, sound insulation characteristics;

2.Respiratory characteristics, regulating indoor and outdoor humidity;

3.Fireproof; Green bricks:

1.Extremely breathable and absorbent;

2.Strong density, good frost resistance, no deformation, no discoloration;

3.Strong plasticity.

3. Comparison of shortcomings.

Red Brick: 1High hardness and lack of toughness;

2.It is not environmentally friendly and cannot be used.

Green bricks: 1**High;

2.Difficult to match;

3.It will lead to poor indoor lighting.

Fourth, ** comparison.

Red brick: the standard specification is 40mm*115mm*53mm, which is controlled by about the yuan;

Green bricks: **Around the yuan.

Blue bricks have a very high status in the history of Chinese architecture, and red bricks are also quite standard in the field of modern architecture. The antique style prevails at the moment. Our architectural design is all about the beauty of ancient architecture.

Personally, I think the blue brick building is better, antique, and very charming.

1. The materials are different, the production materials of red bricks are relatively like clay materials of low purity, mainly made of clay plus shale and coal gangue crushed, mixed to make impurity materials, dried and fired with oxidation flames. The green brick is made directly from clay, without other impurities, using water plus blending, oxidation.

2. The process is different when firing, when the red brick is fired at 900 degrees Celsius, it is naturally oxidized and red. The firing temperature of green bricks is even higher, reaching 1000 degrees Celsius, and after the firing is completed, water is used to cool it instead of natural cooling, which leads to a chemical reaction and the brick appears cyan.

The difference between green brick and red brick.

1. Red brick is the cheapest one in most building materials, its surface is porous and has a certain thermal insulation and thermal insulation effect, and the hardness and durability are good in the traditional sense, so it is widely used in the masonry of the wall, and many honest buildings are using red bricks as building materials. 2. Green bricks are better in terms of corrosion resistance and compressive strength. Red bricks were gradually emerging on the architectural stage in modern times, and it was not until the state promulgated that the firing and use of red bricks were about to be banned, and red bricks were gradually withdrawn, but clay hollow bricks then jumped on the big stage of construction.

And gradually recognized by the majority of the people.

3. Green bricks belong to sintered bricks, the main raw material is clay, and the clay is mixed with water and then extruded. Then it is added to the brick kiln and baked to about 1,000 degrees Celsius, and then cooled with water to let the iron in the clay not completely oxidize, which has good resistance to weathering and water. Red bricks are sintered building bricks made of clay, leaf rock, coal gangue and other raw materials, which are crushed, mixed and kneaded, and then dried and fired at high temperature with oxidation flame.

4. The red bricks are burned inside and out with a large fire, and then the fire is extinguished to make the kiln and the bricks cool naturally, the air circulation in the kiln is sufficient, and a good oxidation atmosphere is formed, and the iron element of the brick is oxidized into ferric oxide. So it's rendered red. After the bricks are burned through, the green bricks are directly poured into the kiln, because the temperature in the kiln is high, the water can quickly become water vapor, blocking air circulation, and in the state of lack of oxygen, the ferric oxide in the bricks will be reduced to ferrous oxide, thus presenting the green bricks we see.

5. Green bricks are stronger than red bricks, with good alkali resistance and strong durability, but the firing process of green bricks is complex, high energy consumption, small output, high cost, and it is difficult to realize automatic and mechanized production, so it is higher than red bricks, generally 2 3 times that of red bricks. Red bricks are simple to produce, have high production efficiency and are widely used, but red bricks are solid bricks, which require a large amount of clay, resulting in large clay loss, so the production of clay solid bricks is now prohibited.

The difference between <> green bricks and red bricks is that the raw materials and processes for production are different, resulting in different colors and properties.

The raw materials for production are different.

Green bricks are mainly made from sludge and clay that are processed from iron in the raw materials used to produce them, so they appear dark green or dark gray. Red bricks, on the other hand, are mainly made of red clay that are made from raw materials that contain no iron, so red bricks will appear red when made at high temperatures.

The process is different. Green bricks need to go through a high-temperature firing process during the production process, which can enhance their hardness and compressive properties. Red bricks are mainly dried by natural drying processes such as sun drying and air drying, which makes them more fragile than hall rocks and suitable for building walls and masonry.

The application is different. Green bricks are suitable for buildings in high-pressure environments, such as bridges and foundations, because of their excellent hardness and compressive properties. Red bricks, on the other hand, are suitable for buildings with low pressure loads, such as houses and building walls.

Expand your knowledge:

Both green bricks and red bricks have certain applications in the construction of imperial buildings, but at the same time, the development of modern industrial technology has also appeared a new type of material - cement bricks. Compared with traditional bricks, cement bricks are not only more advanced in the production process, but also more advantageous in production costs, and can be applied to more building environments, becoming one of the most widely used brick materials in the construction field.

Green brick and red brick are two different building materials that are often used in different places and uses. The differences are as follows:

Material: Green bricks, also known as gray bricks, are made of clay and other timber materials, while red bricks are mainly made of red clay.

Color: Green bricks are dark in color, usually gray or brown. The color of red bricks is different from the kiln temperature, the burning state and the composition of the clay, showing reddish-brown, red, purple-red and other colors.

Strength: Red bricks are stronger and more durable than green bricks, and can withstand greater pressure and torque.

Use of Fan Chunziwei: Red bricks are widely used in houses, bridges and other building structures, while green bricks are mainly used in small and medium-sized buildings and interior walls, wall columns, foundations, etc.

Blue brick building or red brick building, which one do you feel better? What is the difference between green bricks and red bricks.

1. Different raw materials.

The raw material of green bricks is clay, which is fired in a brick kiln after being extruded with water, and finally cooled with water so that the iron in the clay will not be completely oxidized; Red bricks are made of shale, clay, etc., which are crushed, mixed, dried and sintered at high temperatures.

2. Different firing processes.

The firing process of green bricks is different from that of red bricks. The red bricks are fired over a large fire. During combustion, iron oxide is produced and has a red color; Raw bricks, on the other hand, need to be cooled with water during the firing process so that the iron in the clay is not oxidized to cyan.

Green bricks are the most durable and durable, red bricks are the cheapest, and cement bricks are the most environmentally friendly. Both green bricks and red bricks are actually made of clay, but burning green bricks goes one more step than burning red bricks.

The clay used to make red and green bricks is clay, which contains iron ion inorganic salts. Iron ions are unstable. When it burns at high temperature in the furnace, it will be oxidized to form reddish-brown iron oxide, which can see the color of red bricks.

When the red bricks are burned in the kiln, a large amount of water is poured into the roof of the kiln. At high temperatures, a large amount of water vapor is immediately produced to isolate the air. The lack of oxygen causes the coal to burn incompletely, generating reducing CO, which reduces the iron oxide to black iron oxide and blue-black iron oxide, thus forming the color of the green bricks.

Therefore, the color of the green bricks produced by each batch of brick kilns is uneven.

Cement brick is a new type of building material. It is made of cement, fly ash and slag through high-pressure molding technology. Cement bricks are lightweight, better than green bricks and red bricks, and can be made into various types of bricks according to needs, and can also be cut directly at the construction site.

Cement hollow bricks reduce the use of raw materials, light weight, easy to transport, and also reduce the labor intensity of construction personnel.

Cement bricks gradually replaced green bricks and red bricks.

Both green and red bricks are fired from clay, which requires a lot of clay and consumes coal, causing environmental pollution. However, cement bricks are made and hardened from cement, fly ash, and power plant slag that do not require coal. They have little pollution to the environment, light weight and high strength.

As a result, the state has vigorously promoted the use of more environmentally friendly cement bricks, and many cities have banned the use of green and red bricks to build houses and replaced them with cement bricks.

Although cement bricks have many advantages, the combination of cement bricks and plastering mortar is not as good as green bricks and red bricks, and it is easy to form cracks on the wall, so green bricks are more durable, red bricks are second, and cement bricks are third.

Due to the splashing of water and repeated redox, green bricks are denser and stronger than red bricks. It is more resistant to pressure and water and does not peel off easily. Therefore, after hundreds of years of wind and rain, the ancient blue brick buildings are still standing.

However, the generation process of this color is very demanding, so the ** of green bricks is also higher than that of red bricks.

I prefer the green brick building, from the quality of the green brick and red brick their manufacturing process is almost the same, the process and hardness are relatively similar, but the plasticity of the green brick is very strong, can reflect a classical charm, will give people a quiet and simple beauty, so I prefer the green brick.

Personally, I think the red brick building is better, the cost is relatively low, it gives people a sense of elegance and calmness, and the quality is also very good.

Red brick buildings, such buildings look particularly good-looking, and they are particularly beautiful, and have a particularly fresh feeling.

First, from the characteristics of bricks.

Red bricks are generally made of loess, through crushing, mixing with water, made by manpower or equipment, after drying, put into the brick kiln, burned through the fire and then stop the fire, wait for the cooling of the bricks.

Because the brick kiln is open to the pores, so the gas in the kiln is relatively smooth, O2 is abundant, and the copper element in the green body is oxidized to ferric oxide, so its color is red. The production process of red bricks is simpler than that of green bricks, and today's brick and tile factories are all mechanical automatic manufacturing, and the productivity is also very high, which is widely used.

Defects of red bricks.

Poor intensity. Because the sand of the red brick material is the yellow mud on the top of the mountain. Yellow mud is less smooth, and the viscosity and relative density are insufficient. After incineration, small round holes in the shape of bubbles are formed inside, which leads to poor performance of the impact function of bearing capacity.

Before you build a house in the countryside and have not yet put it on the ashes, you can take a stick and knock it twice, and the surface will be shattered. Imagine that in ancient times, it was possible to fight anytime and anywhere, whether it was the ancient city wall or the key administrative organs, if red bricks were used, it was very easy to be conquered by the opponent.

Poor corrosion resistance. If the surface of the red brick is not coated with concrete, it will become soft after being exposed to the sun and rain, and it will be like toast bread with slag at the end. If red bricks were used in ancient times, many historical and cultural heritages may not be visible to us.

Characteristics of green bricks.

The soil used for green bricks is mostly low-lying clay with strong stickiness, and most of it is obtained from farmland. In modern times, in order to better maintain farmland, it is not allowed to mine soil and burn kilns in farmland.

Its processing technology is similar to that of red bricks, except for a different cooling process. When the bricks are burned to a similar degree of ripeness, they are poured with cool water to cool them, and then put them into the kiln after pouring, and dry them with the warmth of the kiln.

This whole process is a bit similar to the heat treatment of quenching, and after this process, the brick is very strong and hard. During the whole process of rapid cooling of bricks, the red** compounds in the bricks are transformed into gray-green cheap compounds, and then the blue-green color that people see is established.

Green bricks have high hardness and strong corrosion resistance. In the historical buildings and historical cultural heritage that you see today, you can feel the thickness of the historical time accumulation of green bricks. After thousands of years of rain and wind, it is still standing.
