What is aerated brick? What is an air block brick???

Aerated block is a new type of building material that is lightweight and porous. The aerated block produced by aerated block equipment has the advantages of light bulk density, high thermal insulation efficiency, sound absorption and good processability, and can be made into wall blocks, thermal insulation blocks, pressure plates, floors, wall panels and thermal insulation pipes. Aerated blocks have been widely used in industrial and civil buildings and pipeline insulation in China, and have become an important part of new building materials.

Aerated blocks are divided into fly ash aerated concrete blocks and sand aerated concrete blocks. Among them, fly ash autoclaved aerated concrete blocks are prone to problems such as wall cracking and hollowing after being used in construction projects due to their high water absorption rate and large dry shrinkage. Since January 1, 2014, Huai'an City will eliminate fly ash aerated concrete blocks in the city's construction projects, and promote the application of self-insulating autoclaved sand aerated concrete blocks for exterior walls and autoclaved sand aerated concrete blocks for interior partition walls.

Each design unit is required to indicate the strength, bulk density, thermal conductivity, specifications and other parameters of the material in the design documents when selecting materials.

It's a stone that can float on the surface of the water – some people call it a pumice stone! The pores in the middle make this material very light—also known as lightweight bricks, lightweight walls; It also makes this material able to block sound - also known as soundproof bricks, soundproof bricks; Because the material contains a lot of air - also known as aerated bricks, aerated blocks; At the same time, this material has good thermal insulation performance - also known as thermal insulation bricks, energy-saving bricks; The most important thing is that it is made of concrete and has high strength, so its technical name is - autoclaved aerated concrete block.

Aerated brick cracks are cracks on aerated bricks, or cracks that appear on the wall.

Aerated concrete blocks, referred to as aerated bricks, are aerated concrete blocks produced by high-temperature autoclaving equipment technology. "Aerated brick" can be understood as a simplified or generic name. The range of products covered should be larger, that is, bricks produced by various other processes, including steamer pressing.

Aerated concrete cutting is a new type of wall material made of stone powder, cement and lime as the main raw materials, prepared by raw materials, pouring, cutting and molding, and curing by high-pressure steam. It is mainly used for non-load-bearing wall masonry and frame structure filling.

Block is a man-made block for masonry, which is a new type of wall material, the shape is mostly right-angled hexahedron, and there are also various special-shaped blocks. The length, width, or height of one or more of the main specifications in the block series exceed 365mm, 240mm or 115mm respectively, but the height of the block is generally not more than 6 times the length or width, and the early length of the long day is not more than 3 times of the high song late cavity.

Block is a block-shaped building product that is larger than clay bricks. Its raw materials are wide and varied, and they can be taken locally and cheaply. According to the size, it is divided into three categories: large, medium and small.

At present, China mainly produces small and medium-sized blocks. Those with a height of 380 940 mm are medium-sized; If the block height is less than 380mm, it is small. According to the material, it is divided into concrete, cement mortar, aerated concrete, fly ash silicate, coal gangue, artificial ceramsite, slag waste and other blocks.

According to the structural structure of the block, it is divided into two types: dense and hollow, and the hollow ones have hollow blocks such as round holes, square holes, oval holes, single row holes, and multiple rows of holes. Dense or hollow blocks can be used as load-bearing walls and partitions. China is one of the earliest countries to adopt blocks, as early as the 30s of the 20th century, Shanghai used small hollow blocks to build houses.

In the 50s, Beijing, Shanghai and other places used cement, sand, slag, lime, etc. to produce small and medium-sized blocks. In the 60s, Shanghai and other places used fly ash, lime, gypsum and slag to make fly ash silicate medium-sized blocks, and also developed block forming machines and light spreaders, which promoted the development of block building. Fly ash silicate medium-sized blocks have been widely used and continuously improved.

In recent years, the floor block crane has been developed, and the construction technology has become more mature.

Air brick is an excellent new building material, and has the advantages of environmental protection. It has the following advantages: Light weight:

The general weight of aerated concrete blocks is 500-700 kilograms per mu, which is only equivalent to 1 4-1 3 of clay bricks and lime sand bricks, and 1 5 of ordinary concrete.

Aerated concrete block is a new type of building material that is lightweight and porous, thermal insulation, good fire performance, nailable, sawable, planable and has certain seismic resistance. As early as the early thirties, China began to produce this product, and is widely used in Shanghai International Hotel, Shanghai Building, Fuzhou Building, People's Bank of China Building and other high-rise buildings. It is an excellent new building material.

And it has the advantages of environmental protection. 1.Light-weight aerated concrete blocks generally weigh 500-700 kilograms cubic meters, which is only equivalent to 1 4-1 3 of clay bricks and lime sand bricks, 1 5 of ordinary concrete, noisy fiber is one of the lighter in concrete, suitable for the infill wall of high-rise buildings and the load-bearing wall of low-rise buildings.

Using this material, the dead weight of the whole building can be reduced by more than 40% compared with that of ordinary brick-concrete buildings. Due to the reduction of the weight of the building and the low destructive force, the seismic resistance of the building is greatly improved. 2.

The thermal conductivity of aerated concrete is generally 0 degrees of 0 degrees of 0 hours of thermal insulation performance, only 1 4-1 5 of granular soil bricks and lime sand bricks, (the thermal conductivity of granular soil bricks is 1 4-1 5 degrees; The thermal conductivity of lime sand brick is kilocalorie m o h o degrees), which is about 1 6 of ordinary concrete. Practice has proved that the thermal insulation effect of a 20 cm thick aerated concrete wall is equivalent to the thermal insulation effect of a 49 cm thick clay brick wall, and the thermal insulation performance is also much better than that of a 24 cm brick wall.

In this way, the imitation thickness of the wall is greatly thinned, and the effective usable area of the building is expanded accordingly, the thickness of the building material is saved, the construction efficiency is improved, the project cost is reduced, and the self-weight of the building is reduced. 3.High strengthAfter experiments, the compressive strength of aerated concrete blocks is greater than 25 kg square centimeters, which is equivalent to the compressive strength of No. 125 clay bricks and lime sand bricks.

4.Good seismic performance.

Questions. Are air bricks suitable for bathrooms? Can you tile it?

Yes, dear.

Questions. What is the impact of doing hydropower?

No, it's safe.

Questions. Air brick or cement sand small red brick wall, which one is stronger?

How thick the walls of the air brick mounted security door are.

All have their own characteristics, which should be judged according to actual use. Now hollow brick is a relatively new material, which is later than the stage of development of red brick, and the thermal insulation effect of hollow brick is very good, and the overall weight of the building is reduced. But hollow bricks will also have disadvantages, such as poor seismic performance.

Because the middle is hollow, the load-bearing capacity of the side slag excavation is slightly poor, and the advantages of red bricks are lower than those of hollow bricks, and the construction difficulty will not be very large. You can do some modeling, but red bricks will also waste a lot of materials, because red bricks are solid.

Aerated brigade blind brick is an excellent new building material, and has the advantages of environmental protection. It has the following eugenic points: light weight:

The production of aerated concrete blocks can make a large use of industrial wastes such as fly ash, tailings sand and desulfurization gypsum, which is in line with the development of circular economy strategy and is a new type of wall material encouraged by national policies.

However, due to the different conditions for the use of local resources by various enterprises, the raw materials and formulas selected are different, and quartz sand will generally be used.

or tailings) is called "sand aerated block". It is used as an infill wall for buildings and is the best self-insulating wall.

Features:

1. Light weight and high strength.

The bulk density of absolute dry is 500-700kg m3, which is a standard brick.

of 1 4, clay brick 1 3. Therefore, it can effectively reduce the self-weight of the building, reduce the foundation and structural input, and is very suitable for the frame structure in various industrial and civil buildings.

and buildings with weak geology.

2. Thermal insulation.

The thermal insulation performance is 7 times that of clay bricks, 10 times that of ordinary concrete, and 3-4 times that of clay solid bricks, and its thermal conductivity.

Usually. With 20cm thick products to make the exterior wall, its thermal insulation and hail insulation heating effect is equivalent to that of 49cm solid brick wall, warm in winter and cool in summer, greatly improving living conditions, saving energy, and increasing the usable area of the building.

Autoclaved aerated concrete blocks, referred to as aerated bricks, are generally aerated concrete blocks produced by high-temperature autoclaving equipment processes. "The range of products it covers should be a little larger, i.e. brick macroacacia products produced by various other processes, including autoclaving. Aerated brick performance:

1. Light weight The general weight of aerated concrete blocks is 500-700kg m3, which is only equivalent to 1 4-1 5 of clay bricks and 1 5 of ordinary concrete, which is one of the lighter in concrete. It is more than 40% lower than the weight of ordinary brick and concrete buildings. 2. Good thermal insulation The thermal conductivity of aerated concrete is 1 6 of ordinary concrete, and the thermal insulation performance is much better than that of 240mm thick clay brick walls.

3. Strong seismic capacity Aerated concrete has light capacity, good overall performance, and small inertia force, so it has a certain seismic capacity. 4. Good processing performance Aerated concrete has good processing performance, which can be sawed, planed, nailed, milled and drilled, which brings great convenience and flexibility to construction. 5. It has a certain high temperature resistance When the temperature of aerated concrete is below 600 degrees, its compressive strength increases slightly, and when the temperature is about 600 degrees, its compressive strength is close to the compressive strength at room temperature, and the fire performance reaches the national first-class fire protection standard.

6. The internal structure of aerated concrete is like bread, and a large number of closed pores are evenly distributed, so it has the sound absorption performance that general building materials do not have. 7. Strong adaptability can be tailored according to different local raw materials and different conditions. The raw materials can be selected river sand, fly ash, mineral sand, etc., according to local conditions.

It can be used as waste, which is conducive to environmental protection and truly turns waste into treasure. Aerated bricks are shockproof (better than red bricks): Aerated bricks are elastic because they have hollow characteristics, while the main body of the building is supported by a reinforced concrete structure, and the bricks only play a filling role.

When it happens, the reinforced concrete structure will be deformed, if it is a solid brick, the reinforced concrete structure will have nowhere to expand and contract, and it will burst and collapse. The use of hollow bricks can leave a good expansion space for reinforced concrete structures.
