The characteristics and dimensions of silicate blocks , especially construction

There is a well-founded belief that gas silicate blocks organically combine the characteristics of two different materials - stone and wood.But perhaps the main reason why many owners choose to build parts of it from gas silicate - low cost operations.And when you consider the huge range of these products, it becomes clear that it seems a good opportunity to make the best choice of products both in their linear parameters and for the intended purpose.

Characteristics of gas silicate blocks assigned to the components used in production.The main of them - quartz sand (and the smallest fractions) and lime.The composition of the mixture includes the cement, but its share is very small.As with most manufacturing artificial materials, certain additives are used, that "adjusted" certain properties of the final product.

Judging from the reviews of people who already live in their own homes from gazosilikata, they believe that it is not wasted money.On the Internet, taken a lot of information dedicated to the description of this type of cellular concrete.But for the most part it is full of specific terms, symbols, so certain provisions be clear only to professionals and those who are "not in the subject," many questions remain.

It makes sense to analyze the characteristics of gas silicate blocks from the viewpoint of an ordinary person, an individual developer's perspective.It will be clear advantages and disadvantages of this type of product.But first you need something to explain.

All these further linear dimensions of silicate blocks - in "mm", weight - in "kg".But since manufacturing technology is quite simple, they are engaged in the production of not only large companies but also small firms.That is they are generally not subject to particularly care about the desired parameters (including wear and because of the equipment), so that all values ​​below - typical, although some differences may be in fact.

Consider the competitive advantages gazisilikata:

Possibility of work self

This is one of the determining factors in the choice of building material.

First , all the blocks are relatively lightweight.For example, a sample with dimensions (length - height) x 600 100 5 to 16 (depending on the density of the material);to 600 x 200 products - not more than 30 (with the same width of 300).Therefore, they are easy to transport and to move on the ground.Hence, there is no need for mechanical lifting devices.In addition, the edges can not only be smooth but with the "slots".Incidentally, there are units with linear and parameters: width 50, 250, 400, thickness - 250, and others.

Second , samples easily processed (sawn, cut, trim, drilled, sanded).

Third , such surfaces can decorate almost any material (good adhesion), which expands the ability to host an independent structure finish.

Ease

1. All gas silicate blocks have the exact dimensions of the (if not the products of "artisanal single»):
2. Bond products is made using a special adhesive mixtures.It means for "building site" will not be hot sand, cement, and hence the dirt.
3. These units give small shrinkage, therefore, if the material quality, it does not have to "tighten" to finish the house - it can be done in parallel with the construction of
4. blocks can be compactly stored even in a small area.Typical (the most common) linear dimensions are: length and width of all the blocks is the same - 600 and 300, and the thickness of - 100 or 200;
5. accurate calculations can be made when determining the required volume of purchases.Therefore, spend the extra money is excluded;
6. reduced construction time, as it does not require careful fitting, alignment, and so on.A minimum of gaps will eliminate the need for their incorporation.

Versatility in application

Depending on the characteristics specific to the product units can be used for the construction of load-bearing structures, internal walls and partitions, as well as for additional insulation.Therefore, they are divided into categories - structural, thermal and "universal" (construction-insulating).

Performance

• data blocks of aerated concrete is much stronger, so there is no particular difficulty in the placement on the wall of any objects (cupboards, shelves, paintings and so on), do not require special dowels;
• house from silicate blocks quite warm.In the opinion of the owners, if at all stages of the construction was all done correctly, compared with brick buildings on heating savings can reach 25 - 30%;
• indoor climate is maintained at a constant level.This is due to the fact that the material is able to "breathe".In this it is similar to the timber;
• due to the porous structure provides good insulation;
• fire safety as well as sand, lime and cement are non-combustible materials.

moisture absorption

That it imposes certain restrictions on the use of gas silicate.For example, in areas with excessive humidity will be required surface finish of the walls.The most common way - plastering.The same applies to the outer walls.As an option - their quality spetssostavami treatment for waterproofing (impregnation, of coating, injection).We must focus on the local conditions and the appearance.This artificial stone - white, so many "private owners" prefer to make additional trim or textured plaster or paneling.

have gazosilikata there is one feature which should be indicated.All blocks have a porous structure.Some types of "porosity" product can reach 85%.Therefore, all products differ in density (D).Most samples are used in the private housing construction (for load-bearing structures) are the figure between 400 - 700, while the maximum - 1 100.

And here it is necessary to consider the relationship - the denser (and therefore stronger) unit, the worse it retains heat.Conversely, a different porous high heat saving.Therefore, when buying products or need to focus on the "golden mean", or opt for one of the properties, but to hold a series of supporting activities.For example, if the strength is important (for the building of several storeys), then it may be necessary and additional insulation.

Those who decided to build out of gas silicate, can give some practical recommendations.

1. If in the future is expected surface finish of the walls, you can significantly save by buying cheaper units - the second grade.They may have slight defects, but after facing all the shortcomings of the material will be hidden.Based on 1 product price difference is small, but when you consider the volume of purchases made, the total value of the consignment is quite palpable.
2. second way to save money - the choice of optimal product thickness.It should provide an acceptable (or required) reduction of heat loss when "single-row" masonry.
3. you can save on the discretion of the manufacturer.If the products are "imported" in its overall cost and are included in the cost of transportation.From this point of view, more profitable to buy local production units.
4. There are many tips for choosing the samples.In particular, if they are not flat faces, and "pazogrebnevye", that is easier to work with them (move, stack).This is undoubtedly true.But we must consider the fact that when installing such articles mixture flow, which blocks are fastened together increases significantly.The cost of such adhesives are not too high, but it is for 1 pack.How many of them will need in the process of construction?So before you buy gas silicate, it is advisable to remember the math and calculate everything thoroughly.
5. When selecting the adhesive you need to pay attention to indicators such as the "open time" of the mixture.If it is minimal, then it can not be something to correct, align.
6. Given the diversity of Manufacturers, in determining the required number of blocks it is advisable to clarify their linear dimensions in a particular point of sale.This will make more accurate calculations.
7. units produced by heat treatment (autoclave), much stronger and better analogues have not undergone such a procedure.And although their costs are higher, they fit much better for residential buildings.
