Red bricks: description and varieties

The most popular and famous building materials on the right recognized red brick. Buildings from it can be found on every street. From such elements, a variety of buildings are manufactured, from the surrounding household buildings to high-rise buildings. Today we will get acquainted closer with this popular building materials and find out which kind of varieties exist.

Advantages and disadvantages

Red brick, like many other building materials, has both positive and negative sides. You must read with them if you are planning to purchase such a product.

First, consider what these products are good.

  • Red brick boasts a rather long service life without loss of an attractive type.
  • This building material is presented in the widest assortment. In the relevant outlets, you can easily find options of various shapes and sizes. Of these, it will work out to form the designs of the most different structure.
  • This building material was rightly recognized by one of the easiest and unpretentious in the masonry, so working with it can both experienced masters and beginners.
  • Buildings from this raw materials are well-soundproofed.

  • High-quality red brick is not afraid of a high content of dampness and moisture, so you can safely build room type baths.
  • In case of wetting, red brick dries quickly.
  • Thanks to this, the material, the dwelling is created as a comfortable microclimate, to be in the conditions of which – one pleasure.
  • A number of defects that may appear on the surface of such building materials can be eliminated independently.
  • Properly manufactured red brick is not afraid of any low, nor high temperature values.
  • Facial brick is featured aesthetic manner, so it is often used for the purpose of facing.
  • This building material is environmentally friendly and is not applied in either human health nor the environment.

Unfortunately, the red brick is not devoid of flaws. Consider them.

  • The walls raised from this building materials are bad because they are immediately noticeable formed by the generics. As a rule, such flaws appear due to the use of a low-quality solution or material itself.
  • Porous bricks can not boast of high reliability, since in the cold period are especially strongly exposed to the destructive effect of water. In such conditions, these products begin to collapse. The liquid that fell inside the brick under conditions of low temperatures can easily break it.
  • Different parties of bricks can have small differences in the shade, which can spoil the overall picture when facing.
  • In modern outlets too often there are parties of red bricks having poor quality. As a rule, they are issued for good products, but they actually leave much to be desired. In many cases, at first glance, it is simply unrealistic to identify a second-round brick.
  • When choosing optimal options, there is no possibility to check out absolutely all of their qualities without referring to specialists and special laboratories.

Characteristics and composition

Red brick is a common building material to which many users appeal. From it build buildings and houses of various configurations. This building material has certain characteristics that should be considered when it is selected.

  • Strength characteristics. Red brick is a fairly solid building material. This parameter is indicated by the letter “M” and the number. These designations should be paid to the selection of high-quality and suitable products. Distinguish bricks “M” 25-100. The higher the digital marking, the more impressive load is able to withstand the material for 1 sq. cm.
  • Frost resistance. Resistance to low temperature values ​​is measured by the number of cycles. Each cycle consists of 2 main procedures – first bricks are lowered into the water for 8 hours, and then in a similar time gap moved to the freezer. The level of resistance to frost is determined at the moment when building materials will change some of its characteristics.
  • Thermal conductivity. This characteristic is no less important than the same frost resistance. The coefficient of thermal conductivity indicates the volume of heat that can pass through the wall with a thickness of 1 meter in a temperature difference in 1 degree on both sides. This indicator is measured in watts. Than he is significant, the more weak are the heat-conducting properties of building materials.

There are 5 separate categories of efficient red brick. Each of them is characterized by the ability to restrain the heat in the inside of the available room. The minimum thermal conductivity is characterized by a full-scale brick type.

The main characteristics of this building material are directly dependent on the components present in its composition. High quality product is the opportunity to get using good clay. So, the facial type of brick is obtained from fine clay. The best is the material to be made from clay composition without additional additives. In most cases, bricks make such clay, which is not suitable for the preparation of other ceramic products.

It should also be noted that ingredients are often used in the production of red bricks, in the content of which are present:

  • kaolinitis;
  • Ilit;
  • Montmorillonite;
  • quartz.

To the primary properties of clay intended for the production of bricks include:

  • High plasticity – raw materials should not be crumbly, if it is kneading, and should also keep a form (you can meet absolutely non-viable clay);
  • binding ability – clay remains quite plastic after adding auxiliary components;
  • Shrinkage – in this case, it is meant to change the size during drying and firing;
  • The properties of schukebility – here it means that the ability to solve when heated;
  • refractory – along the heating of the clay should not be melted.

In many cases, in the manufacture of high-quality red bricks, not only one clay is applied, but also various additives. They allow you to get a more reliable and attractive building material. Such additives include:

  • slag, ash and sand;
  • Coal and peat powder, wood sawdust;
  • ore with iron;
  • sandstone;
  • Metal oxide.

How they do?

The technology of making high-quality red brick is quite simple and understandable. In this case it is imperative to choose a suitable raw material and competently process it. Processing with such works is carried out in several stages. The required form, the appearance and structure of the popular building material is formed by the following steps.

  • First thing crushing clay. After that, it for a long time is thoroughly mixed until the consistency becomes homogeneous.
  • After that, additional components make and give products the necessary form.
  • Then bricks are exhibiting to be dried to leave moisture. It should evaporate slowly from all sides (inside too). If errors were made at this stage, then the resulting brick is simply cracking and collapsed.
  • Next, the resulting material is subjected to a firing in a temperature of 800 degrees. The higher the melting point will be, the stronger the individual components of the product will be connected to each other. In this case, the masonry material will not be destruction or deformation.

Experts argue that the competent firing of red brick is the ability to determine the sound. It should be rather ringing and pure when hitting. This indicator will indicate good quality product.

If the brick melted too long or in the conditions of high temperatures, then inside it turns out to be black. Similar (incorrectly burned) building material can not be acquired for the manufacture of so important bearing walls.


Currently, several varieties of red bricks are distinguished. They differ in a number of characteristics.

  • Ceramic. This variety of red brick is recognized as standard and is most often found. Ceramic copies make from burnt clay or a combination of several types of its varieties (more often than 3).

  • Silicate. Such a brick is made in a special autoclave. At the same time we use sand and lime. The color of the finished material depends on the added additives.

  • Private. This is a simple red color material used in the construction of wall structures, cesspools and other similar bases.

Subsequently decorated with different building mixtures, such as plaster.

  • Facial. This category includes chamotte and porcelain bricks, the top layer of which is covered with a special crumb. Such options are applied to facing and decorative work. Similar types are characterized by high cost.

  • Hollow. This type of red brick is porous and consists of a large number of different different holes. It is characterized by good thermal properties.

  • Forthoty. This is a brick in which there is no. Such materials usually differ in weak thermal qualities, but are more dense.

  • Convex. Such varieties of red brick are produced and one and a half, and single. They have a non-standard shape and are more expensive than classic clay copies.


Choosing a suitable batch of red bricks, you need to pay special attention to its marking. So, the elevation parameter of these materials is indicated as follows:

  • 1 NF (single versions) – 6.5 cm;
  • 1.4 NF (semi-liter) – 8.8 cm;
  • 2.1 NF (double) – 14 cm.

Extremely rarely on the Russian market there are bricks that have a marking of 0.7 NF – these are options related to the “Euro” category. Their height parameter is standard and is 6.5 cm, but the width is modest – 8.5 cm.

Another red brick is equipped with a brand in the form of the letter “M” and numbers from 50 to 300. These indicators indicate the biggest pressure (as mentioned earlier – with a difference of 1 degree on both sides). So, products with marking M50 is permissible to apply only in the manufacture of fences or partitions.

As for any types of walls, it is recommended to use the M75 brand brick, or M100. If you need to build a spectacular arched structure, then you need to refer to materials with a brand not lower than M125. To prepare the caps and the foundation foundations, it is worth applying brick M175 and M150, as well as use other, more durable materials.

Scope of application

The scope of the quality of high-quality red brick is extremely wide. This sought-after building material is used in the manufacture of the following bases:

  • walls;
  • fences;
  • arched structures;
  • partitions;
  • sidewalks;
  • enclosing and supporting structures;
  • decorative trim / lining;
  • fireplaces;
  • chimneys;
  • in the manufacture of furnaces;
  • From the brick make foundations and socles.

Separately, it is worth allocating a very popular brick lately with the effect of “actions”. It turns out adorable structures under the old. For example, it may be a chic “old” fireplace. With the help of such an object, you can radically change the appearance of the interior, giving it a special style and chic.

How to choose?

Choosing a suitable batch of popular and durable red bricks, it is necessary to pay special attention to the following important parameters.

  • Dimensions. Selecting the Red Brick, pay attention to its dimensional parameters. So, the standard options have dimensions – 250x120x65 mm, one-time (modular) – 250 × 120 × 88 mm and 250 × 120 × 130 mm, narrow – 250 × 60 × 65 mm, thin – 250 × 22 × 65 mm. And it should also be taken into account and the mass / density of the material selected based on its structure (hollow or full-scale).
  • No damage. Carefully examine the selected materials. On high-quality red brick, there should be no serious damage and chip. In addition, such products should not have a pale pink shade – this will indicate that the products were not properly burned. Brick should be hit – the sound from the blow should not be deaf.
  • Strength. Make sure the brick you have chosen is durable and reliable. To check these properties, you can knock on the hammer item. Low-grade options after these checks turn into crushed stone, the elements of the average strength are divided into several small pieces after several shots, and high-strength varieties of such bricks only spark.

  • The presence of defects. Look at the surface of the red brick. On the surface of these building materials, noticeable whims of divorces are often observed, which are marriage arising due to the exit to the surface of building materials of soluble salts. Brick exposure to the supreme cannot be determined by conventional methods. For this, special chemical tests are usually carried out.
  • Good seller. Specialists recommend purchasing red bricks from proven vendors who have a good reputation in your city. In addition, they are not advised to acquire too cheap batches, because they may be low-quality.

Do not save on the purchase of red brick, if you plan to build really high-quality and durable buildings.
