Hublex block
. Of course, the most important and most used application of بلوک هبلکس is for wall covering it is a building
In 1924, a Swedish architect named Johan Erickson, after conducting various experiments, realized that if the material is activated by heat, a porous concrete product
It is created with a very high resistance, so these blocks are called Hablex, ACC or Autoclaved Aerated
.concret
After that, the countries of Sweden, Germany, and England use ash instead of silica and replaced Heblex block, but today more than 450 manufacturers in 41 countries of the world produce بلوک هبلکس and offer it to construction manufacturers
In fact, Hablex block is a type of porous concrete that is used in buildings, similar to materials or concrete that are made by autoclaving, or aerating, Hablex block Because the silica used in Heblex block has a very high melting temperature, it has heat insulation properties and this causes the Heblex blocks to be insulated, as a result of using
These blocks are a good substitute for wood for building builders and can help nature a lot because its main ingredients can be completely recycled and returned to nature's cycle
Heblex block ingredients include silica with 0 to 100 micron grain size, water, cement, lime, aluminu
powder and a very small amount of gypsum..or they say porous light block
In the past century, the technology of research and production of autoclaved aerated concrete, or Hablex blocks, has been developed a lot, and for the construction of A walls in China, Hablex blocks are used for
Buildings with 65% energy saving with self-supporting class grade are used as partitions or filling frame structures and low walls
According to the researches, all kinds of necessary tests are performed for the microstructures and the composition of the ingredients, such as the size of quartz particles, the autoclave process and the wet and dry circulation of the environment
Hablex block is usually produced through autoclaved aeration from ingredients including lime, cement, sand, water and aluminum powder
According to today's need for environmental protection, the raw materials of Hablex blocks have been transformed into various industrial products and other wastes that usually contain silicon and calcium
Industrial by-products mentioned above include materials such as silica fume, fly ash, copper tailings, blast furnace slag coal, research has shown that rice husk ash is used as a substitute for fine aggregates, which increases the strength and density of the block. by reducing the time and temperature of the autoclave
Also, in China, the thermal conductivity of Hablex block is used in civil buildings, the density of which varies from 0.13 to 0.22, 400-700 kg/m3
The thickness of the outer walls made with Hablex blocks in cold residential areas is less than 400 mm and cold non-residential areas is less than 300 mm, this work causes heat conduction of Hablex blocks to reduce the thickness of the wall
As one of the essential components of walls, mortar plays a very important role in loading and transferring heat
first stage
The first step in making هبلکس blocks is to make a mixture of silica and water. We combine a large amount of silica with water to form mud-like materials. In a separate mill, we mix dry lime and cement and add it to the main slurry. It should be balanced so that the ingredients are not dry or too thin
Special mixers are used to make the raw materials of Heblex blocks and mix them
second stage
There are a series of fixed molds into which the Hablex block material is poured, each of these molds has a capacity of three cubic meters, but only half of the molds are filled with materials and the aerating step
Heblex blocks begin
In fact, a series of chemical activities causes small bubbles to appear in the material and within about three and a half hours at a temperature of about seventy degrees Celsius, the material is molded to the full size
From these steps, the product created is ready to be cut and transferred to the production line
third level
In the quality control production line, it is one of the very important steps that the product, or the hebelx block produced before entering the main production line, must be checked to ensure that it is sufficiently ventilated. The cutters usually adjust the size of the blocks according to the customer's needs, but it must be noted that the size of the blocks should not be much higher than the standard below
Final level
At the final stage, the Heblex blocks enter the autoclaves, the heat temperature of the autoclaves is about 200 degrees Celsius, and they are baked with a pressure of about 12 atmospheres. After the baking of the Hablax is finished
The final product is ready to be used in the market. It should be noted that if the Hablex block is produced according to the mentioned methods, it will be very safe and strong, and it is a very good
insulator for moisture, cold, heat, and sound
How to use and use the heblex block
Chinese wall steps with Heplex blocks
چسب هبلکس Raising the first row with the Hablex block
In the Chinese wall, raising the first row is very important. For the first row, the best suggestion is to use the same traditional mortar, i.e. cement and sand. After finishing the work and raising the first row, it is better to wait for 48 hours until it dries complete
Wall hanging with Hablex blocks
The principles and generality of the Chinese wall with Hablex blocks are the same as the traditional method, for example, the vestibule of the walls, the vertical execution of the walls, etc. must be observed
Adding mortar or Hablex glue
Special mortars, which are usually based on polymer cement, should be used to put Heplex blocks and wall tiles together
Usually, these materials are produced by the manufacturer and are used horizontally with a block with shoulder spatulas with a thickness of about two millimeters
Connecting Heplex blocks to the structure and to each other
Plate nails are used to connect the tongues of the Hablex block to each other. In fact, a metal nail is hammered into the vertical seam of both blocks and connects both blocks to the coil or shape from one side to the wall of the structure. Now, in order to connect the Hablex block to the wall of the structure, one piece is fixed and on the other hand, it is connected to the block with two large wood nails
.This L-shaped piece should be used every 75 cm from the wall of the structure
Hablex block has many more advantages than the old materials. Next, we will discuss the advantages and disadvantages of these blocks
Advantages of Heplex block
Heat and cold insulation (cold and heat) Hablex block is a very good insulation for cold and heat in terms of its structure, according to the new building laws, the structures must be properly insulated, and this causes the block to be replaced
The style is replaced by older materials by the builders
Being insulated reduces energy consumption, Hablex block does not transfer heat easily, and this makes the heat of the environment not easily lost, especially in the winter season
The low weight of the Hublex block
One of the best features of Hablex block is its very light weight compared to old materials such as brick and... For example, Hablex in size 60 x 25 x 20 is equivalent to 46 bricks, but in terms of weight
It will weigh as much as 4 bricks
Heblex block resistant to earthquakes
Structures made with Hablex blocks have a significantly lower weight, which makes them more
resistant to pressures and stresses

Hablex sound insulation block
Nowadays, due to the increase in the number of units and crowded buildings, one of the main problems is noise in buildings. Heplex block has the advantage that due to its structure and
Despite the small bubbles in it, it breaks the sound as soon as it hits the sound and the amount of noise is significantly reduced
Hebelx fire insulation block
Due to the use of silica in the construction of Hablex blocks, the transfer of fire from Hablex hardly happens, because of this important advantage, it makes it easier to get municipal permits for construction
and it is completely acceptable and there is no need to use any sound, heat and heat insulation
Close the burning room, the amount of heat transferred to the next room does not even reach the point where a piece of paper catches fire
Hablex block wiring
Among the other advantages of Hablex blocks, we can mention its easy and convenient cutting, these blocks can be cut with simple saws
Hablex blocks for moisture and freezing insulation
These blocks are completely insulated against moisture, that's why they can be safely used in the northern provinces of the country, because of the porous structure of Hablex blocks, it is not convenient to get them wet. For example, if in a structure with Hablex blocks If it is made of a burst pipe, this block plays the role of insulation. Due to the fact that Hablex block absorbs very little water, it never freezes. Freezing of the walls in the long term can cause the destruction of the building
The cost-effectiveness of using Hablex in terms of time and cost
The dimensions of Hablex blocks are much larger than other materials with a much lower weight, and this makes the construction workers work faster and more easily. As a result, in terms of
Financially, you will have a much lower cost because much less cement mortar is used. The mortar used for Hablex blocks must be thinner than bricks because in its structure
Heblex blocks use a large amount of cement and mortar used only to stick the blocks together
After the porcelain wall is finished, wet the whole wall to make sure that the blocks and the mortars are well attached, so that water reaches all parts, any part of the wall that is not wet means that the blocks are not well attached. The probability that the wall will fall easily is very high. After this step, we must wait for the wall to dry well so that we can plaster the walls
For the walls that are made of Hablex blocks, the layer of plaster used should be up to one centimeter because it is used as a moisture barrier in other materials, but for the walls with Hablex blocks, it is only for beauty
is used Because in European countries and Sweden, Hablex and style blocks have been used for many years, but in our country it is not well known and is not used much
Disadvantages of the Hublex block
Light blocks cannot bear a lot of weight and therefore they are only used for walls such as interior walls that are not supposed to bear too much weight
In the past century, the technology of research and production of autoclaved aerated concrete, or Hablex blocks, has been developed a lot, and for the construction of A walls in China, Hablex blocks are used
For buildings with 65% energy saving with self-supporting class grade, it is used as a partition or filling frame structures and low walls

Also, in China, the thermal conductivity of Hablex block is used in civil buildings, the density of which is 400-700 kg/m3 and varies from 0.13 to 0.22
The thickness of the external walls made with Hablex blocks in cold residential areas should be less than 400 mm and cold non-residential areas should be less than 300 mm, this will cause the heat conduction of Hablex blocks to reduce the thickness of the wall
As one of the essential components of walls, mortar plays a very important role in loading and transferring heat
