Why does the country not allow the construction of brick and concrete houses? -wellcamp light steel villa manufacturers
Bricks can be seen everywhere. The status of bricks in the construction industry is not an exaggeration to be called a legend. It was once indispensable and very common in people's lives. So why is it not used in building houses now, and the government is also banning it in large numbers? Some people hold the attitude that it doesn’t matter to them, and feel that building this house will not have much impact on the environment, so they still use it secretly. . Each of these flukes adds up, and in the end human beings will suffer. It may be difficult to tell just by looking at it, but the firing process of bricks is actually very complex. Borrow soil. The soil used for burning bricks is commonly known as clay. After being exposed to the wind and sun for half a year, its interior is decomposed and loosened by natural erosion, and then it is manually crushed and sieved, leaving only fine pure soil; Add water to moisturise and knead repeatedly like noodles. Of course, it is definitely not with your hands. You can step on it with ox force to make thick mud. It takes about 5 to 6 times to turn the mud and refine it manually; When shaping, the soil should be compacted, and the place where the bricks are placed should be covered with fine sand to prevent adhesion; the bricks should be dried in the shade, and after the bricks are completely dry (about one to two months), they can be fired in the kiln. This is the most important part. General bricks use coal as fuel, while filter bricks with higher density are slowly burned with wheat straw, pine branches and other fuels; after more than ten days of burning, the green body is sintering. If the fire is slowly turned off at this time, the outside air will enter the kiln, and the common red bricks will come out! The craftsmanship is complex but traditional, and requires a lot of cheap labor. You must have seen this phenomenon. A village opened a brick factory, and most of the villagers went to work. In addition to the serious failure of environmental protection production in these brick factories, the protection measures for workers are also extremely poor. Every year, the number of accidental deaths caused by poor safety at work in brick factories only increases. Moreover, people who have been exposed to soil, burning coal, etc. for a long time are more likely to suffer from respiratory diseases than those who do not! This is also the most fundamental reason why our country bans brick and concrete houses!
