How are eco friendly bricks made? What material is the new environmentally friendly brick made of?

Generally speaking, the use of fly ash, cinder, coal gangue, tailings slag, chemical slag or natural sand, mud, industrial waste, garbage incineration slag, etc. (one or more of the above raw materials) as the main raw materials, without high temperature calcination and manufacturing of a new type of wall material called environmental protection brick. The use of industrial waste fly ash, sand and gravel as the main raw materials, and put a certain proportion of chemical modifier through scientific batching for chemical thermal reaction, the use of unique technology, add a certain amount of cement and a pollution-free environmental protection curing agent, through fever-free foaming molding. The product has a smooth and beautiful appearance, high compressive strength, bright gray and uniform color, strong durability, good anti-cracking and anti-seismic effect, good frost resistance and plasticity, and is an indispensable material for the construction of housing construction, pavement and floor laying, fence construction, etc., and has a good market prospect.

The unique interlocking structure of environmental protection bricks reduces the cost of sand dredging, lime burning, and transportation, and also reduces the process, and the construction speed is faster. Therefore, it seems that the unit price of environmentally friendly bricks is higher, but in fact, the overall cost will be cheaper than the use of ordinary bricks. Environmental protection bricks are interlocking, and they can also reduce the generation of garbage to a certain extent, which is a very environmentally friendly material.

The size of environmental protection bricks is different, and the size of aerated bricks is relatively small (width 200 mm): 600 100 200; 600×100×240;600×100×250;600×100×300;600×120×200;600×120×240;600×120×250;600×120×300;600×125×200;600×125×240;600×125×250;600×125×300;600×150×200;600×150×240;600×150×250;600×150×300;600×180×200;600×180×240;600×180×250;600×180×300。

The use of fly ash, cinder, coal gangue, tailings slag, chemical slag or natural sand, mud, industrial waste, garbage incineration slag and so on (one or more of the above raw materials) as the main raw materials, without high temperature calcination and manufacturing a new type of wall material is called environmental protection brick.

The product is in line with China's general policy of "protecting farmland, saving energy, adapting measures to local conditions, and taking local materials", in line with the opinions of "strictly restricting the destruction of fields and burning bricks and actively promoting the reform of wall stoves", and in line with the Ministry of Finance and the State Administration of Taxation has issued the Cai Shui Zi (1996) No. 20 document "Notice on continuing to implement preferential value-added tax policies for some comprehensive utilization of resources", and the product is fully exempt.

Brick banquet round noisy is a kind of rectangular stone used for building walls, made of clay firing, mostly red, commonly known as "red bricks", there are also cyan "green bricks". The size of the Chinese standard clay brick is 240 115 53mm, and the purpose of this size is to ensure that the ratio of length, width and height of the brick is 4 to 2 to 1.

Bricks: According to the different parts used in construction projects, bricks are divided into wall bricks, floor bricks, arch shell bricks, floor bricks, sewer bricks and chimney bricks. According to different architectural cavity bending energy, wall bricks are divided into load-bearing bricks, non-load-bearing bricks, engineering bricks, thermal insulation bricks, sound-absorbing bricks, facing bricks, flower plate bricks, etc.

According to the characteristics of the production process, bricks are divided into two categories: sintered products and non-sintered products. According to the different raw materials used, bricks are divided into clay bricks, shale bricks, coal annihilation stone bricks, fly ash bricks, slag bricks, lime sand bricks, etc. According to the shape, bricks can be divided into solid bricks, microporous bricks, perforated bricks and hollow bricks.

Ordinary bricks and special-shaped bricks, etc.

The use of fly ash, cinder, coal gangue, tailings slag, chemical slag or natural sand, mud, industrial waste, garbage incineration slag and so on (one or more of the above raw materials) as the main raw materials, without high temperature calcination and the manufacture of a new type of wall material is called environmental protection brick.

The product is in line with China's general policy of "protecting farmland, saving energy, adapting measures to local conditions, and taking local materials", in line with the general policy of "strictly restricting the destruction of fields and burning bricks and actively promoting the reform of the wall", and in line with the Ministry of Finance and the State Administration of Taxation has issued the Cai Shui Zi (1996) No. 20 document "Notice on continuing to implement preferential value-added tax policies for some comprehensive utilization of resources", and the product is fully exempt.

The difference between environmentally friendly bricks and traditional bricks.

First, in terms of its weight comparison, red bricks are made of clay fired at high temperature, and the weight is larger, but the environmental protection bricks are pressed by cement, cinder, etc., relatively speaking, the weight of environmental protection bricks is relatively light, which is more convenient for transportation and construction.

Second, from the perspective of environmental protection, red bricks will be mined in the production of soil, which may lead to over-exploitation of resources and cause some adverse effects, in addition to red bricks in the firing, will produce some pollutants, easy to pollute the environment. However, since the name of environmental protection bricks, its environmental protection is generally better, and its production is made of waste, without high-temperature firing, and the environmental protection is better.

Environmental bricks are just a general name, and there are many kinds. The aerated bricks produced with cinder are relatively light, but the strength and waterproofness are poor, and they are more suitable for non-load-bearing interior walls; The porous bricks produced from coal gangue, fly ash and shale are relatively strong and waterproof, and can be used as exterior walls.

According to the technical requirements for environmental labeling products HJ T 207-2005 The scope of construction blocks "light aggregate concrete small hollow blocks, autoclaved aerated concrete small blocks, fly ash blocks, gypsum blocks, sintered hollow blocks" belongs to the scope of environmental protection bricks.

Together, the two concepts are environmentally friendly bricks.

1. The materials are environmentally friendly. Brick making uses waste as the main raw material, such as soot, silt, garbage and other wastes.

2. Use environmental protection. The use of bricks is energy-saving and environmentally friendly, such as thermal insulation, non-polluting buildings and living rooms.

【Introduction】The porcelain sediment left after kaolin beneficiation is usually discarded, which not only occupies the land, but also pollutes the environment, how to solve this problem? At present, some enterprises in our city are using it to produce porcelain clay bricks, turning waste into treasure. Industry insiders believe that under the situation that the state prohibits the production of solid clay bricks, it is very meaningful to promote the use of environmentally friendly porcelain clay bricks.

Commentary] This is a production of porcelain clay bricks in our city, according to reports, the production process of concrete porcelain clay bricks is to use the remaining porcelain mud and sand after kaolin ore beneficiation and other raw materials according to a certain ratio, after the hydraulic brick machine high-pressure forming, and then after a period of natural curing and concrete coagulation, in this way, porcelain clay bricks can be applied to building construction.

Xu Jian'an, the relevant person in charge of the environmental protection brick factory: After the identification of the Chaozhou City Quality Inspection Station and the Chaozhou City Quality Inspection Bureau, the strength indicators are much higher than the red bricks, and the general red bricks are about 6 (megapascals), and our bricks have reached more than 10 megapascals.

According to reports, the characteristics of concrete perforated bricks are: ** It is almost the same as traditional red bricks; The light weight of bricks can reduce the weight of the wall, and its thermal insulation, heat insulation and sound insulation effects are far better than those of red bricks, which can greatly reduce the energy consumption of buildings. At present, there are many buildings and real estate in our city that use this new type of environmental protection brick, and the effect is obvious.

Commentary] Our city is the main ceramic production area, the annual use of kaolin ore is about 1 million tons, the resulting porcelain sediment has 500,000 tons, not only occupies the land, but also pollutes the environment, if these porcelain sediment can be fully utilized, 300 million porcelain mud and sand bricks can be produced every year. Using it to replace solid clay bricks is equivalent to saving about 500 acres of land, saving about 20,000 tons of coal and reducing sulfur dioxide emissions by 500 tons per year. At present, some enterprises in our city are increasing investment, improving production capacity, and opening up the rural construction market.

Huang Nan, the person in charge of the environmental protection factory: At present, the (sales) network in the rural market has not yet been established, as an enterprise should focus on the vast rural market, so that farmers can use environmentally friendly lightweight bricks.

Commentary] During the interview, the reporter learned that although the state has long banned the production and use of solid clay bricks, in some rural areas of our city, illegal brick kilns have been repeatedly banned, and solid clay bricks still have their market, the reason is that some people still have misunderstandings about bricks, and the sales network of new wall materials in rural areas has not yet been established.

Fellow Voice] Villager: This (red brick) is relatively strong, and it is burned by fire. Those who are not burned by fire are earth-born.

Villagers: (Red bricks) It is easier to carry, there are brick kilns in front and back, and they will arrive as soon as they are transported, but it is too far to carry.

Commentary] relevant people believe that in order to make solid clay bricks really withdraw from the market, in addition to law enforcement departments to increase the crackdown, porcelain mud and sand brick manufacturers should also find ways to reduce costs, in order to further reduce the quality of porcelain clay bricks, and at the same time establish a perfect rural sales network, so that the vast number of rural people feel the benefits of using new village building materials, so as to consciously resist the use of solid clay bricks.
