Red brick and green tile is a microcosm of ancient Chinese architecture, in the past, red brick was once popular in the streets and alleys, is a large number of production and widely used building materials. Whether it is urban or rural, people will prefer red bricks to build houses. Because it is both beautiful and stable and cost-effective, but I don't know when it started, even in the countryside, it is rare to see this kind of solid red brick to build a house. Why is this happening?
It turned out that as early as 1997, the state promulgated a document prohibiting the firing and use of red bricks, requiring the cancellation of red bricks in three to five years Since red bricks are so popular for economical and durable fire insulation, why does the state prohibit red bricks from building houses?
Red bricks, also known as clay bricks, are made of clay shale gangue, etc., which are crushed and mixed and then pressed and formed by hand or machine. After drying, the sintered building bricks made of oxidizing flames at a temperature of about 900 Degrees Celsius are oxidized into iron trioxide during the process of flame burning to cooling, so most of the bricks are red.
[Breeze] consumes a lot of fuel
However, in the process of high-temperature firing, a large amount of fuel is consumed, such as non-renewable resource coal, and a large number of harmful gases are generated, such as sulfur dioxide carbon monoxide.
[Breeze] pollutes the environment
In addition, most of the brick factories are not complete and the management is not standardized, and these gases cannot be reasonably and effectively treated, which has a great impact on the air quality, the health of the surrounding residents and the growth of crops, which is a very serious environmental problem.
[Breeze] destroys arable land
In addition, the raw material of red bricks is clay, and clay needs to be obtained from cultivated land, so that a large amount of land will be destroyed, which will directly lead to a reduction in the area of cultivated land.
According to relevant statistics, the country needs to spend more than 700,000 mu of land every year to burn red bricks, which is equivalent to nearly 600,000 people losing cultivated land every year, and this method of firing waste of land resources is likely to involve food security issues, so the state prohibits the use of red bricks to build houses.
So what to use to build a house without red bricks? What materials can replace red bricks, and will they be better than red bricks when used to build houses?
With the changes of society and the development of the times, people have more choices for building houses, such as hollow bricks, which are large in size, light in weight, light in quality, good in raw materials, less in terms of consumption, and cheaper, and are now widely used in the construction industry.
Or cement bricks, the use of cinder cement as raw materials do not have to go through high temperature calcination, the production process is simple and more environmentally friendly.
Or foam bricks, this material is simple and lightweight, not easy to deform, stable and does not pollute the environment.
Or is a new technical product Hairong module, it is made of modified hair-vinyl polystyrene particles after heating foaming, polystyrene foam plate module, with earthquake-proof moisture-resistant salt and alkali heat preservation easy installation and other excellent properties.
Seeing this, you will know why the country banned red brick houses, it is not only a lengthy process, but also pollutes the environment and destroys cultivated land, and even seriously affects people's physical health. Times change it is not the only choice, friends, what bricks will you choose to build a house?
