Which material is better in the construction of expanded clay or foam block

The last decade has been marked by a breakthrough in technology in construction. A large number of new materials have appeared, and the old and proven gave a new lease of life. It became much better with the choice, everyone can count on their finances and choose the option more convenient in a particular case. The well-deserved popularity of cellular concrete blocks: expanded clay lightweight concrete, aerated concrete, etc. Due to the porous structure, they are lightweight and low cost with sufficient strength. Europeans and our builders like these building materials for their environmental friendliness, so they are widely used for the construction of houses of different floors in many countries.

Claydite block and foam block

Why has the popularity of building with blocks increased?

For the construction of low-rise houses are increasingly used expanded clay blocks, expanded clay blocks or gas blocks. This can be explained by several advantages: Their size is slightly larger than conventional bricks. For the construction of the wall requires a smaller amount of bonding material. The laying process is simplified because of this; Изображение пеноблока

  • Correct geometry;
  • Construction adhesive can be used instead of regular mortar. Thin joints need a small amount of compound and will not serve as cold bridges during operation;
  • The porosity gives good thermal insulation. Prefabricated walls in one aerocrete or foam block can not be further insulated;
  • The materials are fully compliant with environmental standards and do not emit harmful substances when high humidity or high temperature;
  • The low density and weight of individual expanded clay lightweight blocks or aerated concrete blocks allows the construction of houses to use strip foundation with low-depth or pole version;
  • Construction is carried out without the use of expensive and sophisticated equipment and is within the power even of an amateur. You can significantly save on labor costs;
The main problem, common to aerocrete, expanded clay blocks, foam blocks is the need for protection from the environment. Consider in more detail the positive and negative aspects of expanded clay blocks and foam blocks.

Claydite concrete

Cement mortar with the addition of claydite granules is used for production. For curing, the mixture is poured into prepared molds, to obtain the final product, they are kept at normal temperature for at least 28 days.

The main advantages:

  • The low cost allows you to save money on construction;
  • High strength and thermal insulation;
  • Good noise insulation;
  • Resistance to low temperatures and long operation without loss of properties;
  • Resistance to moisture;
  • Low weight expanded clay blocks;
  • Environmental safety;
  • After the erection of a small shrinkage of the building and the lack of cracks;
  • Can be used for bearing walls and partitions;
  • Well withstand mechanical processing. They can be nailed and easily drilled;
  • The material does not succumb to rot. the formation of fungus and mold;
  • Claydite houses are durable;
  • One block can replace 7-11 bricks. The cost of homes by 40% less than brick.

The material also has some disadvantages:

  • Fragility under dynamic loads and impacts;
  • Surfaces outside and inside buildings need additional alignment and finishing with other materials;
  • Mechanical cutting is possible with special tools.

Foam concrete

Is one of the varieties of cellular concrete. It does not require special equipment and conditions for production. The composition includes cement mortar and special foaming additives. During intensive mixing of the components, a homogeneous mass, saturated with bubbles, is obtained. In the process of solidification and is obtained foam concrete. To obtain the blocks the mortar is poured into the molds for solidification. The material is used as the basic material for load-bearing walls and warm interior partitions.

The advantages of foam blocks include:

  • Good thermal insulation of rooms;
  • Excellent noise-insulating properties;
  • Does not combust and does not support burning in a fire;
  • Good frost resistance;
  • Houses made of them do not shrink;
  • The accuracy of form and good surface of individual foam blocks;
  • Environmental Safety. Harmful substances are not released at high temperature or moisture;
  • Ease of machining. They can be sawn, drilled, milled with hand tools;
  • At the cost of production foam block is 20-25% better than aerated concrete;
  • There is no need for special equipment for production;
  • Low weight;
  • Easy and cheap to transport;
  • The surface is convenient for exterior decoration.

Disadvantages of expanded clay blocks:

The disadvantages include shrinkage of houses in a year after erection. Therefore, it is better to carry out finishing work in a year or a year and a half. The nuances of erecting walls of expanded clay block, gas block, etc. If brick walls begin to be erected from the corners, which are then connected, then gas blocks are immediately laid in rows. After waterproofing the foundation, the first row is laid from the corner with cement mortar. Glue is not used due to the thinness of the layer. With the thickness of the cement mortar, you can set the desired level. The following rows are already placed on the glue. It is applied for convenience and economy with a toothed trowel. In masonry, each successive row is shifted so that the vertical seams do not coincide. The wall can be reinforced to give greater rigidity and strength to the structure. Rows of blocks are reinforced every 3-4 with a thin rebar. Under it it is necessary to make troughs for laying. The horizon is checked with a level, and the evenness of the walls with a cord. The walls themselves are erected much faster than when working with bricks. It is quite possible to make them yourself. Стена из керамзитоблока

Ready-made foam blocks can be sold artisanal production, without compliance with safety standards on the composition. Therefore, you need to know where to buy. This will not happen when buying keramsitoblokov.

From a comparative analysis we can conclude that each material has a lot of positive qualities. Based on them, as well as personal preferences, you can choose what is best for a particular construction. (8 ratings, average: 2.63 из 5)
