What is aerated concrete?
Gas light concrete, which is known as AAC block in the world, is a type of light concrete that is made of materials such as silica, cement and lime. Manufacturers create porosity in the mixture obtained from these materials and process it with the help of an autoclave.
Adhesive materials such as cement and lime react with silica material during the autoclave process and produce hydrated calcium silicate. In other words, free lime reacts and the porous structure of the AAC block is created.
Aerated concrete acquires different properties during the autoclave process. Free lime is created from the combination of cement, lime and aluminum powder, and this structure is sound and heat insulating and will have high resistance against volumetric mass. After passing the autoclave steps, no further processing is needed and the product can be used after cooling.
Characteristics of lightweight concrete
The use of light gas concrete is approved by the building and housing research center. This block has unique compositions. The material of this block produces calcium silicate and hydrated aluminum molecules. which is transformed into Tobermorite in the pressure and heat resulting from high humidity. This material is a type of crystalline material that exists in the earth’s environment and increases the strength and stability of the block.
Among the features of gas light concrete are:
High resistance to fire
No production of toxic gas during ignition
High thermal resistance
No need for separate thermal insulation
Powerful sound insulation
High construction speed
Reducing the consumption of materials during construction

Aerated concrete has many uses. This block has been used in Sweden for 70 years. This issue has brought many improvements in its construction and operation. Aerated concrete is 60 to 70 years old in European countries, but in Asia, the use of this block has been noticed in the last 25 years.
Interblocks can be used to build prefabricated industrial houses, villas, as well as apartments without 4-story metal structures. Light weight and non-structural strength have made the autoclave block to be used a lot. Among other things, the AAC block is used in the following cases:
- Use as a light building block
- Use as a dividing wall
- Application in non-load bearing walls
- Use in ceiling filler panels
It should be noted that light gas concrete is made in different volumetric mass and different resistances. But this block has no structural use and will be used only for non-structural resistance. This product solves the problem of mass production in Asia and Europe. Because it is a quality and affordable product and it can be produced with cheap minerals. On the other hand, the problem of waste from power plants and other industries will be solved.
Reasons for using the autoclave block
Currently, aerated concrete or autoclave block is very popular. Because with the help of this product, many construction needs can be answered. The first issue is the durability of the building. This block has a light weight and greatly reduces the final load of the building. The light weight of the building is very important during an earthquake. This is also effective in securing the building.
Another advantage of the autoclave block is its sound and heat insulation. In clustering, it is taken into consideration to prevent the penetration of sound to the neighboring buildings. This block can be used to prevent the passage of sound. Also, the AAC block has helped to optimize energy consumption. Because it will prevent the passage of heat and the flow of cold air.
Another feature of aerated concrete that has made it one of the widely used materials is that it has an affordable price. Currently, the market demand for this type of block is high, which has reduced the price of the product. On the other hand, cheap materials are used to make this product. Minerals that are available, in this way, the final price of the light gas block is reduced.
Buildings that are built using autoclave blocks have a very high resistance. Also, by spending the right amount, you can build these types of buildings.
What is autoclaved light block?
Autoclave light block is one of the materials that is widely used in the construction industry. Such modern structures are produced using a device called an autoclave. They have many names. Some of the well-known names are light block, autoclaved block, Hablex block, or Siporex block.
These types of products have many advantages and, like other similar materials, they have a very high resistance. Autoclaved blocks are among the aerated structures that reach the production stage by using raw materials such as cement, fine aggregates and expansion material, and because there is gas inside these structures, the concrete volume take
What do you know about autoclaved blocks?
Autoclaved concretes are produced at high pressure temperature using materials such as aluminum powder, lime, silica, water and cement. This type of product is a completely resistant concrete product that contains 80% air.
In addition, we must state that autoclaved light concretes are produced using different molds with accurate and standard sizes, and for this reason, their final form is completely identical and accurate.
These types of products puff up like bread dough in the production stage.
The high resistance that autoclaved blocks have against pressure is due to their production process. Because such products are produced under high pressure or temperature. The numerous advantages of autoclaved blocks have made these devices more attractive to contractors and architects than in the past. Because these products are one of the toughest and best blocks.
Information about the autoclaved block
One of the most important issues that is considered in the selection of blocks for the construction industry is the resistance of this structure against external and internal conditions and factors. Autoclaved blocks are among the products that have high resistance compared to other similar materials. These types of products are more resistant than concrete blocks and are almost a strong competitor in the construction industry for these old structures.
These types of products, which are also known as ventilated blocks or gas blocks, are used in the construction of large towers and special buildings. But with the passage of time, these strong and resistant structures are also used to build private apartments and residential buildings. These types of products are light blocks, which are also known as aac blocks or porous blocks because they are produced by gas reaction.
About how autoclaved blocks are produced ?
AAC blocks, or autoclaved blocks, are produced in such a way that there is a lot of empty space between them, and because of this, these products are light in weight and very efficient, because light weight construction materials make workers laborious. Don’t take too much time to transport these blocks and as a result work efficiency will increase. With these conditions, the speed of the workers also increases.
In addition, autoclaved blocks have the ability to store energy. Special standards are used in the design and construction of autoclaved light blocks, therefore these resistant structures have unique advantages. These types of products have the property of puffing or defoaming because they are produced using special materials.
Features unique to the autoclaved block
Autoclaved blocks or Hablex are among the products that have outstanding features. In addition to being light weight, such products are considered a good insulator against heat and sound, and because they are a good insulator against abnormal effects, they are widely used in construction. In addition, we must add that all types of autoclaved blocks have a very high resistance to fire.
These types of modern structures can be cut, that’s why they use these structures for porcelain walls. Because the workers can cut the autoclaved blocks to the desired size using a wooden saw. In addition to other features of autoclaved blocks, we can point out that these blocks have empty space. In fact, you will realize this when you see these products closely.
The cause of the empty space inside the autoclaved block
The empty space inside the autoclaved concretes is due to the hydrogen that is used with aluminum powder in making these concretes. Of course, elements that have alkaline properties are used in the production of these products, for this reason, when they show a reaction, an empty space is created between them. be equal to the factors of external conditions.
These types of products are produced in such a way that it is never possible for water to pass through these concretes. That is, they are exactly the opposite of the old bricks. For this reason, when the autoclaved blocks come into contact with water, they absorb it. These modern structures benefit from special features due to the empty space inside them, and for this reason, they have been more interested by contractors than other similar materials.
Unique advantages of autoclaved blocks
Autoclaved blocks have structural capability in the sense that they have a very high resistance to high pressure. Because these types of products have reached the production stage according to the set standards. In addition, we should mention that autoclaved blocks, or light blocks, have a lower density than ordinary concrete, but show high resistance to external conditions.
These types of products are used in other countries as a covering. But in our country, they use autoclaved blocks to build walls that are supposed to bear a lot of load. Because the resistance level of this structure is much higher than you think. For this reason, they can be used to build different walls or build roofs and floors of buildings.
Insulation of autoclaved blocks
Autoclave blocks are a very good thermal insulator, which increases the need to use these products in the field of construction. These modern structures are produced in such a way that it can even be used without an insulation layer. But it is always recommended to use that insulation layer in construction using these blocks. In addition, autoclaved blocks have a unique feature that has made them attract more attention.
In fact, the insulation feature of these products is against abnormal sounds. Since these structures are produced using autoclave devices and are porous, high porosity in these structures allows air to flow in them and they are used as a suitable insulator against external sounds. In fact, due to the asymmetric holes inside these structures, this block is considered an irregular insulation and absorbs noise and abnormal sounds.
