The red bricks that were originally common in rural areas are rarely used when building new houses.
Compared with cement blocks processed from gravel and cement, red bricks are obviously more sturdy and durable, and the price is relatively cheap. However, few people use nowadays. Obviously, this phenomenon is not in line with common sense.
Red brick house
In fact, many people may not know that many people don’t want to use red bricks when building a new house, but that building a red brick house has been banned by the state.
As early as the 12th Five-Year Plan in 2012, the country had explicitly banned the production and use of .
So, there are so many advantages to building a house in red bricks, why is it banned by the state?
Advantages of building a red brick house
Speaking of which, in addition to the sturdy and low-priced advantages of building a red brick house, Dachuan said at the beginning, there are actually many more.
red bricks
For example, red bricks are simple and convenient to process, and can be used for local materials;
Red bricks are more comfortable to live in than houses built with other materials, and can play a role in isolating moisture, warm in winter and cool in summer;
Then the house built with red bricks will be more beautiful, and the overall plasticity of the house is relatively stronger. After all, red bricks are smaller in size, and can be used even if knocked on. is definitely a crushing advantage compared to hollow blocks made of cement.
Combined with these advantages, when building houses in rural areas, most people chose to use red bricks, the most cost-effective materials.
Rural red brick house
In addition to red bricks, its "relatives" blue brick , now when building a new house, it is almost impossible to see it.
But even so, there is no saying that blue bricks are banned on . . In some places, custom blue bricks can be produced as long as they are needed.
Blue brick house
Time goes back a few decades, like red brick houses, they are everywhere in rural areas. Compared with blue bricks and red bricks, the production process and performance are actually similar.
But now red bricks are completely banned by the state, while blue bricks are not banned.
Blue brick
What's going on?
history of red bricks
This has to start with history of red bricks .
Red bricks
The earliest red bricks were invented by the clever Romans. They found that after being fired at high temperature, clay will become a material with very high hardness and comparable to stone.
And clay is easy to shape into various shapes. If used in architecture, it is undoubtedly more convenient and efficient than mining stone.
So after many attempts, they successfully invented the method of burning bricks in clay. They made the clay into square blocks. After high temperature firing, square bricks were born.

Later, after repeated improvements, they added fine sand, shale, and coal gangue to the clay to make the burned bricks harder, and the waterproof performance of this brick has also been greatly improved.
Because the bricks burned in this way will appear red, this is the real red brick.
Red bricks
has been passed down to this day. Although the materials used to make red bricks in have been improved to a certain extent, the soil composed of its main raw materials cannot be abandoned.
Apart from the raw material of soil, the firing method of has not changed much. It is fired at high temperature in a special brick kiln.
brick kiln
is based on this simple and crude production process, and the output of red bricks is relatively higher and the price is lower.
In that era, who did not choose materials with higher cost performance?

The reason why red bricks were later banned was actually based on its simple and crude production process.Why are red bricks disabled in
?
First from the material for firing red bricks, uses clay , which is far more than the volume of red bricks, and , while most of the clay in brick kilns are dug from the ground nearby. After all, we have never heard of where clay ore is available.
The clay in the nearby ground is dug out, and the brick kiln will enter the clay from other places, and other places will also be clay dug from the ground. If the ground is not digging enough, the mountain will be dug out. In this way, a large amount of clay will be dug out and burned bricks, which will seriously harm the ecological environment.

The second is to burn red bricks in brick kiln, which requires a large amount of coal as fuel.
With the continuous mining of coal, global coal resources have become tense. Now, even after the winter, the country has begun to implement coal to electricity in many rural areas, and gradually ban coal heating.
Coal heating is prohibited, let alone waste coal to burn bricks, which is absolutely not allowed...
rural areas promote coal-to-gas
In addition to wasting coal, the brick kiln will also produce a large amount of harmful gas during coal burning.
In order to burn bricks more efficiently, some brick kilns often burn them 365 days a year. How many such brick kilns are there in ? The number of them is probably not measured in tens of thousands. After all, in Dachuan’s memory, there were brick kilns in his village when he was a child.
In this way, it is also necessary to consider the air pollution problems caused by brick burning bricks in .

These factors are superimposed, which has led to the country's ban on red bricks.
Why is the blue brick not disabled?
As Dachuan mentioned earlier, although the raw materials and production processes of blue bricks and red bricks are similar, , but blue bricks are not disabled like red bricks . Many people may wonder why does not disable blue bricks together?
Blue brick house
In fact, although blue bricks are not banned, they are not something that ordinary people can use casually.
The current blue bricks are often used as restoration materials and antique building materials for ancient buildings. For example, the restoration of ancient buildings such as houses and city towers, and the construction of antique buildings in ancient cities often use blue bricks.
City walls are being built with blue bricks
And these blue bricks are basically customized, It is difficult for ordinary people to buy them to build a house.
is written at the end
In general, the starting point behind the prohibition of building a red brick house in is good, but in the actual implementation process, the implementation is very difficult.
Therefore, although few people use red bricks to build houses now, some people are using them.
Red brick building is difficult to prohibit
from facing such a phenomenon.
Perhaps, to completely ban red brick building, only if a material with higher cost performance than red brick can it be truly realized...
