What is Concrete Exposure?
Exposed concrete or facade concrete is a prefabricated piece that has a polished and completely smooth surface, with a thickness of about 4 cm, which is produced by combining materials such as: cement, pigment, special fibers and lubricants.

Today, exposed concrete is one of the most widely used concretes used in modern architecture, exterior, interior, flooring, etc. The composition of concrete and the method of execution of exposed concrete are very important to create the overall appearance and the final result of the work. These include using the right size mortar. In order to avoid negative consequences, the relevant principles and laws should not be ignored. The construction and sealing of concrete in an integrated manner can help create a smooth surface without seam lines.

Exposed concrete has a great elegance and beauty and brings a different and unique advantage when applied on the surface. The use of exposed concrete, regardless of its practical aspects, in a residential or commercial place, increases the beauty of the appearance of the building and the attractiveness of the building in question.
This concrete is a green and environmentally friendly material and It dramatically increases the use of natural and green elements in construction. Exposed concrete can be easily integrated and synchronized with modern and contemporary architectural concepts. An exposed concrete, in addition to its appearance, has other advantages such as resistance to fire and freezing. This type of concrete is also a good insulator for sound.
This high resistance of exposed concrete makes it possible to use it in other buildings, such as swimming pools and building floors, in addition to the interior and exterior of buildings. . When it comes to building flooring, attractive appearance and high strength and durability are always two of the most important factors that influence your choice.
How the concrete exposure is executed
How to implement exposed concrete using the grouting method
In the method of implementing exposed concrete using the grouting method, first the grout is made, which includes sand, black and white cement, concrete glue and water. . In this method, concrete blocks that have grooves of specific sizes are arranged in such a way that the protrusions are placed in front of the depressions and they get help from the grout to strengthen.
At the back of each Which of these concrete tiles have embedded wires that can be connected to each other and cause their integrity and as a result the strength of the wall in this way of implementing exposed concrete.
Method of implementing exposed concrete by dry installation method
In this method of implementing exposed concrete, concrete tiles are installed through metal substructure with installation fittings, screwing, Megastone glue, BK2F glue or Tile glue is installed. In the method of implementing exposed concrete using metal substructure and fittings such as corners and screws, two rows of metal profiles placed horizontally and vertically and welded together are used. Angles and screws are used to connect the tiles to the horizontal profiles.
In the exposed concrete implementation method through metal substructure and screwing the tile, tiles with bolt holes are used. has it. First, the vertical cans are welded exactly parallel to the bolt holes on the desired wall. After that, the exposed concrete tiles are connected to the cans by special screws.
In the exposed concrete implementation method with Megastone glue, the cans are placed vertically, like the previous method. Of course, in this case, the exposed concrete tile does not have a bolt hole and glue is used to install it.
In the method of implementing the exposed concrete with BK2F glue, unlike the above case, tiles with bolt holes should be used. are. In this way, we apply this type of glue on the back of the tile and use screws and dowels in the parts that have bolt holes. In cases where the foundation wall cannot be screwed, concrete tiles can be attached to the wall with tile adhesive.
نکاتی که باید در اجرای بتن اکسپوز رعایت شود
The quality of exposed concrete production is an important factor in determining the appearance and useful life of this material. For example, prefab tiles should not have warps and should be perfectly straight at the corners. There should be no cracks on the work surface. Each project has its own installation method, and a specific installation method is selected based on the characteristics and specifications of the relevant project. These factors include the material of the wall, its dimensions, etc.
Dimensions of exposed concrete is another point that must be taken into account in the implementation of exposed concrete. The standard dimensions of this type of concrete, according to the type of design, wall width, etc., are produced in the form of square and rectangular tiles.
