What is a permeable brick? What is a permeable brick

Permeable bricks originated in the Netherlands, and in the process of building a city by the Dutch, they found that the ground after draining the sea water would cause continuous land subsidence due to long-term lack of contact with water. Once the levees along the coastline are breached, the sea can quickly reach cities much lower than sea level, submerging entire coastal cities. In order to prevent the ground from sinking, the Dutch made a small pavement brick 100 mm long, 200 mm wide, 50 and 60 mm high to lay on the street pavement, leaving a gap of 2 mm between the bricks.

In this way, when it rains, the rainwater seeps into the ground through the gaps between the bricks. This is what became known as Dutch brick.

After that, the American Shubloko company invented a pavement brick with strong water absorption function of the brick itself. When the bricks are filled with water, the water drains into the ground. But the bricks drain very slowly, and they can hardly help in heavy rains.

This type of brick is also known as Shubloko pavement brick.

In the nineties, Shubloko bricks appeared in China. According to the principle of Shubloko bricks, China's technicians have invented a kind of pavement brick with permeable holes and good water permeability. Rainwater flows into the ground through tiny holes in the bricks.

It was some time again. In order to strengthen the compressive and flexural strength of the brick. Technicians use gravel as raw material, add cement and colloidal admixtures, so that its permeability speed and strength can meet the needs of urban pavement.

This kind of brick is the permeable brick used on municipal pavement. The ** of this kind of brick is relatively cheaper than the ceramic permeable brick fired with ceramic. Suitable for most regional projects.

What is a permeable brick? I don't know! I'm sorry!

Permeable bricks are introduced in foreign countries, mainly to solve the urban surface hardening, maintain the ecological balance and produce a new environmental protection building materials products, in the process of use can maintain the moisture retention of the ground, high strength, weathering resistance, at the same time there are a series of characteristics such as noise reduction. In the production, slag waste and waste ceramics are used as raw materials, usually twice to form, and the materials used have strong environmental protection.

At present, there are two main types of permeable bricks, one of which is color stone composite concrete permeable bricks, which have the same texture as stone, and are mainly used in luxury commercial areas and hotel parking lots, and are difficult to see in ordinary homes and public places. Another kind of concrete permeable brick, in the process of making the side of the trembling surface is relatively simple and noisy, the use of porous concrete material pressing, this kind of permeable brick is mainly used in roadways and highways and other related places, and this is also a cost-effective and relatively high kind of hole service category.

Permeable brick refers to a special function of pavement brick that can quickly subside the stagnant water through the bricks laid after rainwater or large water flow passes through the ground. At present, almost all permeable bricks on the market are made of sand, cement and other additives pressed by unburned brick machine!

Permeable bricks, according to different brick-making materials and processes, can be made of permeable bricks of different specifications and uses, such as our common bread bricks (Dutch bricks), Spanish bricks, etc., as well as emerging imitation stone pavement bricks, sand-based permeable bricks, etc.!

Permeable bricks, also known as sponge city bricks, have certain positive intentions for solving urban floods and reducing urban heat island effect!

Ceramic permeable brick is a type of brick with good permeability, people may often see ceramic permeable bricks in daily life, but they don't know much about it, what kind of brick is ceramic permeable brick? Today, PCHOUSE will answer them for you one by one.

1. Ceramic permeable brick refers to the high-quality permeable building materials formed by using ceramic raw materials through screening and selection, reasonable organization of particle gradation, and addition of binders, molding, drying and high-temperature sintering.

2. Ceramic permeable brick has very good permeability, and is a new type of landscape ecological material that integrates permeability, combustion retention, wide water retention and height.

3. Ceramic permeable brick is a kind of brick with good ecological and environmental protection performance. Ceramic permeable bricks can be produced from industrial wastes such as ceramic waste, sewer sludge particles, waste refractories, and over-fire gangue, and can be reused, and can be fired into bricks again after crushing.

4. Ceramic permeable bricks have many advantages such as high strength, good permeability, good freeze-thaw resistance, good anti-slip performance, and good ecological and environmental protection performance.

<> "The use of permeable bricks is quite extensive, but you must know its raw materials to avoid affecting the later use. Next, let's introduce what material permeable bricks are made of.

1. What material is the permeable brick made of?

1. Ordinary permeable bricks, which are made of gravel porous concrete materials, and because there are many types produced by manufacturers, they can be used in different production centers.

2. Polymer fiber permeable brick is made by using granite as the main aggregate, and when reproducing, high-quality cement and polymer reinforcing agents are added, and then made through the pressing process. This kind of permeable brick is often used in parking lots, squares, sidewalks, etc.

3. Color stone composite permeable brick, the material used is natural color stone granite, marble, epoxy resin glue, and then developed by advanced technology, it is an economic product, often used in high-end areas, such as commercial streets, large squares, and high-end villa communities.

2. What should be paid attention to in the use of permeable bricks?

1. If the following layer of permeable bricks belongs to the river sand layer, try not to deal with the concrete cushion, otherwise it will lead to a decrease in the permeable effect, and after the later compaction, it is also necessary to do the corresponding base surface on the surface layer to achieve a better effect.

2. Pay attention to the errors. However, after the permeable bricks are paved and fixed, the error between the permeable bricks should be taken into account, and the general control is within 3 to 5mm.

3. The laying direction of permeable bricks should also be paid attention to, as far as possible towards the horizontal, if there is a deviation, it needs to be adjusted in time. In addition, if it is in the rainy season, try not to construct, otherwise it will affect the overall effect, and in the days of construction, it is necessary to ensure that the weather is sunny.

What materials are made of permeable bricks, and what should be paid attention to when using permeable bricks, will be introduced here first. There are many details that need to be paid attention to in the use of permeable bricks, and try to deal with them as much as possible, so as not to affect the normal use in the later stage.

The advantages of permeable bricks: strong ventilation performance, relieving the pressure of the urban water answering system, alleviating the heat island effect, preventing road reflection and skidding, and preventing water on the road.

1. Strong ventilation performance

The ventilation performance of permeable bricks is very strong, and when it rains, it can allow rainwater to penetrate into the ground quickly, so that there will be no water accumulation on the ground, and there is no impact on people's lives.

2. Relieve the pressure on the urban drainage system

In the bad weather of heavy rain, the pressure on the urban drainage system is relieved, and the sewage problem on the road surface in the public area can be well prevented.

3. Alleviate the heat island effect

The interior of the permeable brick is hollow, which can absorb the noise, water and heat of passing vehicles, and can alleviate the heat island effect, which is extremely effective in coastal cities.

4. Prevent the road surface from reflecting and skidding

The surface of the permeable brick is very rough, which can prevent the road surface from reflecting and skidding, and reduce traffic accidents to a certain extent.

5. Prevent water on the road

The permeable bricks will not be flooded on the road after rain, and will not slip on the road after snow, which is convenient for citizens to travel safely.

Permeable bricks *** bad distinction

1. Look at the overall appearance

Nowadays, the more defective permeable bricks on the market are relatively rough in appearance and have very large pores. The service life of this kind of permeable brick is relatively low, because the prominent "feature" of large-pore permeable brick is that it is easy to be blocked by dust, and once it is blocked by dust, the permeable brick loses the effect and value of the permeable brick.

2. Look at the particle distribution

In order to ensure the permeability and permeability timeliness of permeable bricks, the particle size of the particles should be reasonable and evenly distributed. In order to reduce the cost of inferior permeable bricks, a large amount of fine powdery clay and coal ash are mixed into the raw materials, and the particles can be seen on the surface, bottom and side of the bricks, and the particles are not obvious.

3. Look at the inspection standards

In fact, the state has strict regulations and requirements on the permeable aging, permeability rate and mechanical properties of permeable bricks, which is what we often call "national standards" and "local standards".

When we buy, we can let the manufacturer show the data inspection report of the product to see whether the performance indicators of the permeable water brick meet the national standard. Please keep in mind that these three indicators are the "touchstones" to measure the quality of permeable bricks.

4. Look at the batch quality

The quality of see-through bricks can not only look at the quality of a single product, but also the quality of batch products. Due to the manufacturer's process management, raw material control and other reasons, the quality of inferior permeable bricks will fluctuate greatly, especially in terms of specifications, color difference, strength, permeability, etc., which will affect the stability of product quality.

Permeable brick is a new product of environmental protection building materials of the century that was grandly born in order to solve the hardening of the urban surface, create a high-quality natural living environment, and maintain the ecological balance of the city. This product has the characteristics of maintaining water permeability, moisture retention, anti-slip, high strength, cold resistance, weathering resistance, noise reduction, sound absorption and so on.
