Positive properties of foam concrete blocks
Concrete blocks or aerocrete. What's better?
How do you know what is best for the construction of: foam block or gazoblok? And then, and another made of aerated concrete - porous material. But they have a number of distinguishing characteristics. Understand which option to prefer, you can, considered and evaluated the differences between them.
visually distinguish gazoblok from the foam block is very simple:
- The foam block has a smooth, flat surface light color.
- Gazoblok has a relief, rough surface white.
To begin with we shall understand, what components are included in gazoblokov and foam blocks. And what determines the differences in their characteristics.
And aerocrete, and concrete blocks - an excellent choice for building a house
The composition of foam blocks include: water, cement, lime, production waste, for example, blast furnace slag, and of course, the components forming the foam. Most often it is a sulfide lye.
For manufacturing gazoblokov required: water, silica sand, cement, lime, aluminum paste. Many are wary of the use of the last component in the manufacturing process, as this element is a health hazard. But it is important to know that during the processing of its particles are dissolved, so ready units do not carry any threat.
The production of these materials also has a number of significant differences, and this due to different specifications.
Comparative characteristics of various building materials
Features production of foam blocks:
- All components are mixed with addition of a special foam filler. Mixing concrete and foam occurs mechanically.
- The solidification of the finished composition occurs in vivo.
Production of foam blocks - an inexpensive process. That is why it is often taken for mid-level entrepreneurs who want to build your business, but not very well versed in the requirements for building materials. As a result - finished products often have significant variation in size and uneven surface. This adversely affects the quality of the masonry.
Mini production of foam concrete blocks
Features production gazoblokov:
- The porous structure - the result of chemical reactions between the major components.
- Processing autoclave installation gives additional strength to the finished products.
Production of aerated concrete - an expensive process that requires a lot of equipment, so produce such units only at specialized plants. All the products are obtained almost perfect, which greatly simplifies and accelerates the further construction.
Scheme production of concrete blocks
Advantages of foam concrete:
- It has closed pores and less moisture absorption;
- lower cost of material.
Advantages of aerated concrete:
- It is more durable;
- better insulation;
- better quality of the manufactured products.
So, if you are ready for significant investment in order to build a durable house, aerated concrete - something that you need. Expensive? Yes. Qualitatively? Also yes. But do not forget that, giving due attention to the choice of foam blocks, as well as aligning the minor error in help cement mortar, you can get almost the same quality material like concrete, but much save.
The construction of a private house of foam blocks
See this very simple - just to study in the global network offered by the size and price of foam blocks apiece. Say for sure which is better - foam or aerated concrete - it is difficult, but in any case, both materials are an excellent option for construction.
The choice of material. Dimensions and prices of foam blocks
When choosing a foam concrete blocks, size and price - the first thing that usually pay attention. How to navigate in them and choose the high-quality material?
Foam blocks may be of different sizes and shapes
Depending on the application, the blocks can be divided into two broad groups - for walls and interior partitions to create. In the first case it is recommended to use foam blocks 20h30h60. Unit Price will depend on the strength and thermal insulation properties specified on the package. The cost of one cubic meter of blocks - from 2650 rubles.
For the construction of internal walls are traditionally used blocks 10h30h60 see. Their price is slightly lower - from 1800 rubles / m³.
Having defined the manufacturer, size and prices of foam blocks, it is possible to order. But how to understand, how much material you need? In this case, the number of measured cubes.
Sizes and flow of foam blocks. The number of blocks in the masonry to 1 m with the condition that the horizontal bearing pad width blocks (wall thickness) is 30 cm, and the length is 60 cm
As an example, we calculate how many pieces of foam blocks 200h300h600 cubed. Obviously, the dimensions in millimeters, but because we are talking about a cubic meter, and the measurement unit must be translated into meters -. 0.2 m x 0.3 m x 0.6 m Total, it appears that one block contains 0.036 m³. Simple calculations show that 27.78 units per one cubic meter.
House of foam blocks: pros and cons
Having started the construction of the house, first of all the question arises: what kind of material for this pick. Should I choose the blocks, if you want to build a full house? After considering the advantages and disadvantages of the building material by studying photos and designs of houses of foam blocks, widely represented in the Internet network, you will be able to choose.
cellular concrete blocks are cut effortlessly
- resistance to temperature changes. Living in a band with changeable climate in the building material of choice must take into account its ability to withstand the effects of external factors. Foam well tolerates effect of strong winds, high frost and heat, while maintaining the optimum temperature inside the room;
- concrete blocks provide excellent noise isolation, which is important if you are building a house in the city.
Useful advice! Once construction is completed, for the walls can be used not only the usual decorative plaster or compositions for facades. It looks great special tiles, natural or artificial stone.
Disadvantages of foam blocks in the construction of:
- precariousness and fragility. Of course, do not expect that the house of foam blocks stand for 200 years. Eventually, after shrinkage, the walls may appear in the cracks;

Useful advice! When choosing a foam block, be sure to pass it a thorough visual inspection for cracks or oily residue. It features low quality material. Razlomav one block, ensure homogeneity of its structure.
With regard to the construction process, there exist disadvantages can be neutralized by a combination of materials. Perfect for that brick. From it you can lay out the load-bearing walls, which will distribute the load evenly. In this case, you can use both regular and decorative bricks. Thus, the design will be more durable, while maintaining all the advantages of foam concrete. Also often make annexe of foam blocks to wooden houses.
Laying concrete blocks with his hands
To further avoid the appearance of cracks in the walls, particular attention should be paid and the foundation. Better to lay him out of a monolithic slab, using a special monolithic tape with a slight indentation. Extra reinforcement also have a positive impact on the quality of construction.
To increase the strength of the walls of the future house, use a special glue, which layer is applied between the blocks to make them more binding. It is not recommended to use in place of the adhesive mixture of sand and cement, as the seam thickness should not exceed 3 mm, or significantly decrease sound- and heat-insulating properties of the material.
