At the present time, the heavy construction of red bricks caused by the need to build a large number of houses for easy and pro-poor relocations in man city has led to an increase in the price of construction materials, which is not yet available, and there is a certain misperception on the part of the population about the need to build houses with fire-free bricks. As a result, it consulted the construction sector and provided some advice for the construction of housing for the next group of households。

I can't buy red bricks from all the brick factories. I'm waiting to build a house
Do you have to use red bricks? It's not as good as fire-free bricks。

How can there be red bricks with fire-free bricks。
Don't you understand science? Come sit down and i'll give you a ride. The red bricks, from the point of view of stress, are used in the design of houses in general, and the red bricks are safe from the point of view of safety, but as science and technology continue to develop, experts have detected the release of houses built by red bricks with radon gas and gamma rays, the chemical elements that threaten human health. Long-term residence in a house built with red bricks can destroy cells in the human body and lead to diseases. Also, the use of red bricks is not advocated from an environmental perspective. Because the production of red bricks is a large amount of clay and wood for burning red bricks. According to relevant data, a large amount of clay is used every year for housing throughout the country, and if this continues, our clay resources will soon be depleted. This, together with the burning of wood for clay bricks, is compounded by the fact that the wood is already scarce in our country, and if the area of forests is cut off to burn red bricks, the forest resources of our countries will suffer extensive damage. If this situation continues, the ecological environment will be destroyed and it will be difficult to recover! Thus, the state order no. 5 specifies in its regulations that the construction of houses can no longer use red bricks。
I can't use red bricks, and i don't want to use fire-free bricks, because i've heard that the house isn't safe。
That's ridiculous. A relative of mine built a house in the past few years with fire-free bricks. I am telling you that fire-free bricks have much to gain by saving land resources, because they are the main raw materials for the use of dust, river sand, ores, and the traditional red bricks are the main raw materials for the land, which is a waste of our land resources. Brick-free can save energy and save, traditional red brick-burning requires considerable coal resources, generate large amounts of carbon dioxide during the burning process, pollute air quality even worse, from an environmental point of view, it is not subject to the mixing of raw materials, suppress formations, need not be burned, nature is conserved and contributes to environmental conservation, and it is simpler, faster and less expensive than the production of red bricks. Now, the price of red bricks around man city is more than four cents, which is below three cents. In addition, fire-free bricks have the advantages of small size, soundproofing, fire protection, lightness, earthquake resistance and robustness. Burn-free bricks can be used as raw materials with a total of more than 90 per cent of used resources. They can be used as electrical slags, construction garbage, slags, which are very important for environmental protection and waste。
Oh, you know what, it's better to use a fire-free brick than a red brick
A little tip
Whether a brick-free structure can be used
Burn-free bricks (vagated ash, concrete, concrete blocks) must be of mu15 strength and shall be approved in writing by the design unit before they can be used as a mass of the bearing structure。
The material is defined in accordance with the structure design instruction for the body (gb 50003-2011) as follows:
3. 1. 1 scale of mass strength of the load structure
Mu10, mu15, mu20
2. Sterilized ash sand ordinary brick, mu15, mu20, mu25
Mu15, mu20, mu25, mu30
4. Concrete blocks, mu5, mu7. 5, mu15, mu20
According to the above-mentioned provisions, the brick structure does not regulate the structure, but the strength is specified depending on the form in which it is used, and all the form of the body may be used if the strength of the body meets the design requirements。
The type of building used in a brick-constructed building, the size of the building, etc., should be determined according to the basic form of the building, the number of layers, etc., and should be approved in writing by the design unit。
