Advantages of concrete blocks for the construction of baths
The blocks represent large blocks (in comparison with the size brick), made of cellular concrete (foaming + cement mortar). Today, there are many manufacturers of foam blocks, and the material is available in any construction market.
The advantages of the foam block next:
- The foam blocks have large dimensions at a low weight, that positively influences the complexity of the work during the transportation of the material and the construction of the baths of foam blocks.
- The material has excellent heat capacity (several times holds heat better, than brick)
- The foam block has a relatively small cost
- Cellular concrete has high strength and durability
- Bath of foam blocks can build, even for inexperienced gardeners (what can be said about the construction of the baths of profiled beam)
- For that would cut off part of the foam block, you can use a hacksaw (or even a sharp knife)
- Material: fireproof
It should also be noted, that the foam block has a few major flaws, which and spoil the popularity of the material:
- The foam block is not able to withstand heavy loads, therefore, from this material recommended to build high 2-3 storey buildings
- Porous concrete absorbs moisture, because of what the foam block is a sponge and requires additional measures for sealing the bath
Despite the fact, the baths of foam blocks there are two significant lack, they can easily refute. First, sauna at the cottage is for a maximum of 2-storey building, therefore, the foam block can easily withstand the weight of this design. Second, any room requires additional measures for waterproofing, besides, all you need, this foam block to handle the special hydrophobic treatment at the outside and wrap a foil material with an inner side of the building.
Before proceeding to the construction of the baths of foam blocks with their hands, provide you with the technology to calculate required number of blocks.
The calculation of the baths of foam blocks
Before, as you begin to build a bath of foam blocks with their hands, you need to create the project of a bath, and to knock out the estimates for building materials.
As for draft baths, with him you can see in the article: construction of a bath of expanded-clay concrete blocks their hands. Not only the projects of baths, but the technology of construction in this case is similar.
We now turn to the calculation of the baths of foam blocks. That would not have to face a situation, when the end of the construction of baths you did not have nearly 10 blocks, or after the construction has remained more 50 pieces, it is necessary to properly carry out the calculation of the baths of foam blocks.
It is necessary to divide the technology is based on 3 group. The first group – bearing walls, their thickness is equal to 2 blocks, laid on rib. The block size in this case should be 200*300*600 mm. The second group of the inner walls of the baths of foam blocks, which are stacked flatwise in a row. In this case, the block sizes you must use the same first. No last, the third group partitions in the bath, which is as necessary to lay flat in a row, but only blocks of sizes 100*300*600 mm.
Classification groups determined, now consider the very nature of the calculation of the baths of foam blocks. Each unit has its own volume (width, multiplied by the height and length). By simple calculations you can determine the volume of each wall of the bath (the formula is the same). Then calculate the volume, who will occupy the Windows and doors in the bath (the formula is again the same). Well, in the end, of the total volume of the walls is necessary to take the amount of doors and Windows and the resulting divide the result by the volume of one unit. Get the required number of blocks for the construction of baths. Like in any calculations, be sure when calculating the baths of foam blocks, there is a tolerance, equal 5%. About 5% foam blocks can deteriorate during transportation (accurate % you can find out from the manufacturer or seller). That is why the final result of the number of blocks you need to add another 10%, this will be the number of blocks, which you'll need for the construction of baths with their hands.
In addition to the foam blocks, you will need the following materials, as:
- Valve rods, thick 12 mm
- Binding wire
- Sewer pipe
- Fasteners (nails, screws, metal corners, etc.)
- Corrugated sheet
- Materials for thermal insulation, paro- and waterproofing baths
- Windows and doors
- Furnace for a bath
- Finishing materials (siding, lining etc.)
- Wiring and lighting
- Polyurethane foam
This is the minimum of those materials, which is necessary for building bath with his hands. Cursory calculations for the construction of the baths of foam blocks dimensions 6*3 meters would require about 120000 rubles (including delivery of materials).
Now consider the technology of building of the baths of foam blocks with their hands
How to build a bath of foam blocks?
In this article we will not discuss in detail each stage of the construction of the baths of foam blocks, because. separately was already fully considered the stages of creation of any bath.
As we have said, the technology of building of the baths of foam blocks has a lot to do with the technology of building of the baths of concrete, the only difference in the characteristics of masonry blocks, which we will discuss below.
What would you have reviewed every phase of construction baths, we encourage you to read the following articles:
- Building the Foundation for a bath
- How to make a Foundation under the stove in the bath?
- Waterproofing baths
- Insulation baths
- The wiring in the bath
- Creating and insulation of the floor in the bath
- The construction of the ceiling in the bath
- The creation of the chimney in the bath
- The installation of the roof baths
- Interior decoration bath
Now more talk about, how to make a laying of foam blocks in the construction of baths with their hands.
Masonry foam blocks
It should be noted, today there are several basic sizes of the foam block, but for the construction of baths is recommended to use the block, size 200*300*600 mm and a density of D700.
So, the laying of foam blocks must be implemented at the edge, the first row of blocks you need to lay a cement-sand mortar, and the remaining rows to a special adhesive mixture. Please note that, the seams between the blocks should be fine – 5 mm, because. large seams will degrade the capacity building (a so-called cold bridge).
Every fourth row of masonry blocks need to further strengthen the metal chicken wire mesh.
It should be noted, during construction of the baths of foam blocks with their hands, experts advise not to use construction, a laser level, which has a higher accuracy.
Just draw your attention to the fact, what adhesive mixture on the foam block it is recommended to apply special trowel, and put the block you need with the help of a rubber mallet.
Although the structure of the foam block is different from the gas, technology of paving materials exactly the same, so the whole process of construction of the bath you can see on this video lesson:
Well, the last, I wanted to tell you, this tips for the construction of the baths of foam blocks.
What you should pay attention?
During the construction of the baths of foam blocks can be a lot of questions, such as: "What a Foundation is better suited?", "The warm bath?", "What material to use for plating baths inside and outside?", so now we will briefly tell you about, how to build a bath of foam blocks with their hands.
The most appropriate Foundation for the construction of the baths of foam blocks is a continuous footing, which should be at a depth of about 60 cm. The width of the strip Foundation should be 30 cm.
In the outer insulation of the baths of foam blocks makes no sense, but from the inside to carry out the insulation of the bath is recommended with mineral wool.
For exterior waterproofing baths are not advised to use the plastering of the walls, because. the plaster will not provide a good insulation material against moisture. Much better to use a special hydrophobic impregnation and priming. Internal waterproofing of baths recommended using as wall insulation foil material.
For decorative finishing baths inside recommended the Board of battens. External decoration of the baths of foam blocks suggest to carry out siding.
That's all, I would like to tell you about, how to build a bath of foam blocks with their hands! We wish you good luck and patience in this difficult event!
