Why is my country severely cracking down on red brick building houses? Because red bricks have many uses and great functions, they have at least several hundred years of history and are widely used. This is how the "red bricks and gray tiles" in the countryside come from. They also have many advantages. They are warm in winter and cool in summer, low in price, and practical stones. You see, the red brick buildings that have been around for two or three hundred years are now very solid. Do you think they are strong or not?
So, it is also a powerful weapon for some naughty guys to fight in groups. But why is the use of red bricks prohibited?
Red brick construction
In fact, we began to restrict the use of red bricks in 2005, and by 2012, the production of red bricks was completely banned? Why is this? It has so many advantages and is so strong. Everything needs to be seen in two aspects. If you look at the shortcomings of red bricks, you will know why red bricks are prohibited. They damage arable land, have serious pollution, and have poor shock resistance.
Red bricks
When we are talking about red bricks, we do not specifically refer to red color bricks, but solid clay bricks . Its first disadvantage is that it wastes a lot of clay resources. Everyone should know that if you burn a brick, the clay wasted is six or seven times that of a brick.
Where does clay come from? They are all dug from the ground, and over time, a large amount of land will be idle and a large amount of waste of land resources.
Let’s take a look at the figures in 2004. About 600 billion red bricks were produced in the year, and about 1.3 billion legislative rice was used in clay, which means that about 700,000 acres of fertile land was destroyed. The recovery ability of the land is very slow. Once it is mined in large quantities, there is no possibility of growing crops in a short period of time. How can this not be shocking?

The second disadvantage is that the pollution is very serious. Do you know why red bricks are red? After the bricks are made, they are sent to the cave for heating. The power temperature is about 900 degrees Celsius. The bricks are turned off immediately after they are fixed, which is to prevent the bricks from burning. At this time, the oxygen outside the cave entered the cave, and the iron element in the bricks was oxidized into iron trioxide. Because the iron trioxide was red, the bricks were also red.
Our Qin bricks are cyan, because the bricks are watered and cooled immediately after being burned. The iron elements inside are less oxidized, so they are cyan.

However, a large amount of pollution will be formed during the burning of bricks. First of all, it is the waste of coal resources. We all saw small brick factories when we were young, and those big chimneys had never stopped at any time. They were covered with clouds and mist every day.
This will produce a large amount of coal ash and sulfur dioxide . It pollutes the atmosphere very seriously. Acid rain will form on rainy days, speeding up soil acidification, and causing large-scale deaths of crops. The body absorbs sulfur dioxide, which can cause vocal cord spasms, and severely affect respiration.
This analysis shows that red bricks cannot be prohibited. They reduce arable land and accelerate sudden acidification, which has a great impact on agriculture and is also harmful to human health.

The third reason is that red bricks are not safe. As we all know, red bricks are strong, but have high weight. They have little impact on ground floor buildings, but when used in high-rise buildings, they affect the shock-proof effect. They will become very "brittle" and easily crack. We can also conclude from previous geological disasters that the casualties of red brick buildings are relatively large.
So we have planned to stop using red bricks since 2005, and have begun to vigorously advocate new types of bricks, such as cement bricks and hollow bricks . These bricks do not need to be fired, they are simple to make and light in weight. The holes in the bricks can also absorb noise and are relatively cheap, making them good substitutes. Because the times are developing, the red bricks should also enter the dust of history.
Cement bricks
In fact, red bricks were not invented in ancient times. They first originated in Ancient Roman . They are building materials that can only be used by upper aristocrats. Later, they were introduced to Quanzhou, China through Italy. We can still see many red brick buildings in Quanzhou . In fact, the production process of red bricks is almost no different from that of our Qin bricks, but there is only one more step of oxidation.
Red bricks
When you were young, did you live in a house made of red bricks? In the red brick house in summer, you stand in front of the window, look at the green leaves, listen to the long cicadas, and hold a popsicle in your hand. This may be the childhood of many people. The red bricks disappeared, but it’s not too bad, a red house cannot be demolished.
