Polystyrene concrete is an innovation among building materials. If you ask a casual passer-by about what popular building materials he knows for building houses, then bricks and wood will most likely be among the first options. Yes, it has been for the last several hundred years, but still a lot has changed. Due to the development of the system of building technologies, new building materials with improved properties began to appear, and one of these is polystyrene concrete.
In the beginning, the material was not as popular as it is now (due to the fact that the raw materials for its manufacture cost fabulous money).
But in the late 1960s, it turned out to improve the technological process, which reduced the cost. From that moment on, blocks of polystyrene concrete (i.e. PSB blocks) became a fairly popular material, and it became especially in demand for low-rise suburban construction. At the moment, Canada, France, Germany and Canada are the largest consumers of such a practical and inexpensive material for construction work.
Polystyrene concrete is composite, that is, complex in the composition of materials, which is classified as lightweight concrete. Such materials have a reduced density,
which makes it possible to solve several construction tasks at once:
To create the material use:
Polymer granules (which are very similar to foam balls) help to create a lightweight structure of polystyrene concrete.
The low density of aerated concrete and foam concrete is ensured by air pores that appear as a result of chemical reactions.
Two methods are used to make blocks from polystyrene concrete:
Material with different densities can be obtained by changing the ratio of components, as well as using different types of polystyrene granules (the larger the diameter of the polymer balls, the lower the specific gravity and strength).
Disadvantages of blocks made by hand
The presence of forms and a concrete mixer makes it possible to create an established home production of blocks,
but there are still a few comments on finished products:
Yes, the quality of the blocks will affect how durable your home will be.
Advantages and disadvantages of polystyrene concrete blocks
If you think about building a country house, then most owners choose polystyrene concrete blocks as a building material, the advantages and disadvantages of which can be determine due to the granular structure of the material.
The advantages include:
In regions with very cold winters, walls can be protected by additionally insulating or plastering.
But, like any of the building materials, PSB has its disadvantages:
Doors and windows can begin to loosen over time.
The concrete block frame is not combustible, unlike its filler. Polystyrene begins to decompose due to the action of fire, and this leads to a decrease in the strength and heat-shielding properties of the material.
Small, equal to 0.1 cm per 1 meter, but this is exactly 3 times more than that of foam concrete and aerated concrete.
e. acrylic primer).
Now that you know about all the pros and cons, consider what types of material are.
According to the building codes specified in GOST R51253-99, the following products of such categories are provided:
Also, building blocks can be classified according to the scope and size:
8 * 30 * 58. 8 cm, as well as 30 * 38 * 58. 8 cm.
heat-insulating) and have a density from D400, as well as dimensions 9. 2 * 30 * 58. 8 cm and 9.2 * 60 * 58. 8 cm.
Now let's consider in which areas polystyrene concrete blocks are used.
The scope of SIS blocks will depend on the density of the material:
A distinction can be made between ordinary and reinforced (i.e., reinforced blocks).
The mixture is prepared already at the facility, and then used for floor screed, for insulation of the roof, pouring the floor and filling the frame. It is also used for fire protection coatings.
slabs with low density, heat-insulating are produced.
As you can see, the material can be used not locally, but for building a house inside and out.
A little about the quality
There are no problems with the construction of houses from polystyrene concrete - such a building material is quite common.
To determine the quality of a product, you should remember:
Now let's talk about construction.
A house built from polystyrene concrete and having an area of 100-130 m 2 (two-storey) can be built in about 3 months.
The process will go through the following stages:
They should be made from PSB blocks, but you can simply fill with a liquid solution. Before screed the floor, you should arrange the water distribution for the whole house.
They make it and take into account the characteristics of the material. Decorative facade blocks PSB, which have a textured front surface or plaster, are quite popular for finishing.
And, naturally, you can't wait to find out about the price of the material.
Generally speaking, the cost of polystyrene concrete blocks will be 15% higher than that of analogues like foam concrete and aerated concrete ..
. First of all, you should determine the size and grade of the material (thermal or structural). Products with decorative finishes will be 25% more expensive than ordinary ones for construction.
Price in Moscow time for a block with dimensions 59.5 * 37.
5 * 29. 5 cm averaged (for 1 m 3 , excluding the cost for delivery to the construction site), will be:
But, nevertheless, the price justifies itself.
Yes, there are no building materials in the world that do not have flaws.
Each of the species has only a part of good properties, and the rest is safely attributed to disadvantages. Sellers of polystyrene concrete blocks are often not shy and openly deceive buyers by distorting information and properties of blocks. The result is that the material is misused, the construction technology is disrupted, this turns into deep disappointment and a waste of money.
When choosing a material for building a country house, carefully study the characteristics, especially points regarding use and performance. PSB have some advantages over other building materials, and they should be understood and also used for their intended purpose.
