Currently, for the construction of various buildings, including residential ones, expanded clay concrete blocks are increasingly used. A large number of different options for such material are available. Hollow models are especially popular. Today we will talk about the main advantages and disadvantages of these blocks, as well as how to properly lay them.

Peculiarities

Hollow blocks of expanded clay concrete are rectangular building material, the structure of which has one or more holes. Compared to standard full-bodied varieties, the block has a particularly high thermal insulation performance and a lower weight. The presence of voids means lower costs of raw materials, therefore, the cost of the material will be relatively low. Hollow structures can have both through and blind holes.

Advantages and disadvantages

Hollow claydite concrete blocks boast many important advantages.

The most significant of them should be highlighted.

  • High strength index... These building materials are often used as a basis for creating a foundation, as they are a reliable and sturdy option. But it is still worth noting that the level of strength in hollow models will be lower compared to corpulent ones.
  • Environmental friendliness... Hollow claydite concrete blocks are absolutely safe for humans and their health. Only environmentally friendly components are used in their production.
  • Relatively low cost. These construction products can be attributed to the budget category.
  • Simple installation technology... Each person can lay such blocks, without the need to resort to the help of professionals.
  • Sustainability... Such materials are not at all susceptible to decay processes, in addition, they can withstand significant mechanical stress.
  • Fire resistance... Expanded clay concrete is practically not subject to combustion, easily tolerates the effects of fire, so it fully meets the requirements of fire safety.
  • Good sound insulation performance. Expanded clay blocks can also be used to create soundproofing protection in residential premises.
  • Good thermal insulation. Hollow claydite concrete products can significantly reduce the heat loss of wall coverings in the room. Moreover, the more filler is used, the more effective the thermal insulation system will become.
  • Durability... The service life is on average more than 50 years.
  • Low water absorption. Such structures during operation will not absorb moisture and swell or deform.
  • Small mass. Hollow models have a minimum weight compared to other varieties of this material, which greatly simplifies transportation, storage and installation.
  • Minimum shrinkage. After the installation work, these blocks almost do not settle, and the structure remains in its original form.
  • Light load on the foundation. If the blocks are used only for the construction of walls or partitions, then they will not exert excessive loads on the base of the structure, which is achieved due to their low weight.In this case, the foundation will be able to remain stable and unharmed for the longest possible time.

Despite all the listed advantages, this building material also has a number of disadvantages that must be taken into account.

  • excessive porosity;
  • fragility.

Types and their characteristics

Hollow blocks can be of many different types. So, they can differ depending on the number of voids in the structure. It is they who make it possible to make these products much less heavy. Most often used in construction two-void, three-void and four-void samples. In addition, they can be classified into separate groups depending on the shape of the holes. Samples are considered the most popular options. with square and rectangular voids.

Expanded clay blocks can be both open and closed bottom... In the second case, the structure will have holes on only one side. The opposite part will be solid closed. These blocks may vary depending on their specific purpose. So, in this classification, there are the following varieties.

Wall

Such materials are used to form load-bearing walls, in this case, you can take models with different sizes.

They will allow you to create a fairly stable foundation for the structure.

Partition

These lightweight aggregate blocks are smaller, since they will not be exposed to a heavy load during operation.

The mass of such models can range from 6 to 14 kilograms.

Facing

These samples have recently appeared on the market. As a rule, models with blind holes are used as such materials. A special decorative coating is applied to the closed part of the product.

Such models already have a finishing decorative coating, so additional external finishing will not be needed in this case.

All products have their own technical characteristics. Each variety has its own weight and dimensions. But most often you can see samples with dimensions 390x190x190, 400x200x200, 390x190x188 mm. The mass of different samples can vary greatly, as a rule, it ranges from 10 to 20 kilograms. But other products are also produced.

Weight will depend on the number and size of holes in the material.

Applications

Hollow blocks of expanded clay concrete are currently widely used in various construction works. They are bought for the construction of residential structures, in which it is necessary to provide a high level of thermal insulation and sound insulation. Sometimes such models are also used for the construction of utility buildings. Often, these blocks are taken when building a bath in the country.

These structures are constantly exposed to the negative effects of excessive levels of humidity and sudden temperature changes, and expanded clay concrete can withstand them. Blocks can be used in the construction of the frame part of basements and cellars. After all, such blocks are able to maintain a constant temperature regime inside these premises.

In addition, mold and mildew will not form on them, as is often the case with other surfaces.

How to stack?

In order for the structure to serve as long as possible, it is necessary to properly lay the material. To begin with, a sticky mortar is prepared (a cement composition with sand and water), after which a diagram is created, which reflects the future structure. Then you can put blocks. To create the correct geometric shape, a waterproofing layer is first applied, then installation is carried out starting from the corners.

Later you can start laying the rest of the part, all the rows are fixed using the building level. Fastening of products should be done on a cement mortar; you can use special plastic dowels that roll into a knot.
