What determines the difference in consumption figures

Even with experienced bricklayers, it happens that the actual costs of glue exceed the planned ones by 1.5-2 times. The difference in quantity arises from the nature of the construction.

The estimate, as close as possible to the reliable one, is possible taking into account the conditions affecting the masonry, these are:

1. The ratio of the components that make up the mixture. If it contains an increased percentage of sand and various additives, the consumption increases. With a large percentage of adhesives, the declared consumption corresponds to the actual one.
2. Technological process. Manufacturers' calculations are based on technology compliance.It is difficult for builders without sufficient experience to maintain the correct line when laying. For leveling, they increase the thickness of the joint for each block, using more glue.
3. Reinforcement of layers in houses with 2 and higher floors. It will take more mortar to close the mesh that is placed between the blocks. Only then will the connection of gas silicate and other similar blocks to each other be strong.
4. Construction products of poor quality, with surface defects. Overruns cannot be avoided - part of the adhesive goes into the pores, fills in chips and cracks. It is necessary to align the masonry seams, compensating for the irregular shapes of the material.

In addition, the conditions in which the construction takes place lead to an overconsumption of glue. Deviations from the optimum temperature and humidity in one direction or the other make adjustments.

The role of the tool used by the bricklayer is important. It is recommended to use a special bucket trowel, which ensures a uniform thickness of the seam and saves glue.

Polystyrene concrete laying technology using glue

Now it's time to study the progress of work directly. Let's figure out how to properly use the adhesive during masonry work, and what are the main features of the technology.

List of required tools

Let's start our overview with a list of the required tools.

To carry out the work you will need:

Building level,

Rubber mallet,

Construction thread (cord),

Square,

Container for kneading the adhesive composition,

Drill with mixer,

Scraper bucket,

Grater,

Hacksaw,

Wall chaser.

Description of work progress

Stages of laying a block of polystyrene concrete: brief instructions:

We glue expanded polystyrene

It's no secret that polystyrene concrete is used more often than others for insulating structures, since its thermal conductivity is very low, but the density values ​​leave much to be desired. As a rule, they do not exceed the D600 grade.

Why? The thing is that it contains a crumb of polystyrene, and it has an excellent ability to store heat.

And since we are talking about this material, let's take a quick look at how to glue polystyrene foam to concrete.

This can be done in two ways:

1. Using various types of glue,
2. Application of dry construction mixture.

In the first case, it can be: bituminous glue, you can also use latex bitumen emulsion mastic, silicone glue or specialized polyurethane foam.

As for dry mixes, their choice is very large. They consist of a mixture of cement, polymer additives and a plasticizer.

How to stick polystyrene foam to concrete? The work process is quite simple. If glue is used, then, as a rule, it is applied around the entire perimeter and dotted over the entire surface. Sometimes a notched trowel is used to glue the entire board. After that, the expanded polystyrene product is pressed against the wall.

The finished mixture is applied in intermittent stripes over the entire surface, retreating from the edge about 2x-cm. If the irregularities on the wall are small, it is quite possible to use a notched trowel. Subsequently, the slab, as in the first case, is pressed against the wall.

The video in this article will tell you about the preparatory work before installing polystyrene foam.

Manufacturers

A wide range of adhesives for foam block masonry often confuses finishers. How to choose the right composition? How not to make a mistake when purchasing a mixture? What should the foam blocks be attached to?

First, remember a few simple rules:

avaricious pays twice - don't try to chase cheapness
buy goods from a well-known manufacturer with a good reputation in the building mixtures market
when making a purchase decision, take into account the season and temperature conditions under which the work will be carried out - it is advisable to purchase a frost-resistant composition for the winter

And now let's get acquainted with the creators of the most popular adhesives that have earned positive reviews from professionals around the world.

Volma

Volma is one of the leaders in the construction market, which has won the recognition of consumers in Russia and abroad. The adhesive of this brand consists of selected cement, fine sand, filler and pigments of the highest quality. This compound is used for joints of 2-5 mm.

This glue is used by finishers when assembling slabs from aerated concrete blocks.

It is sold in 25 kg paper bags.

Titanium

When the glue-foam from the well-known brand "Titan" first appeared on the market, most professionals were skeptical about this new product. However, after the first applications, doubts about the quality and exceptional consumer indicators of the composition completely disappeared.

Titan products replace cement mortars, are very easy to use - you just need to apply a strip of composition to the blocks and fix them. At the same time, construction is progressing quite quickly, and the finished structure is durable and stable.

When applying foam glue, it is worth adhering to several rules:

• the surface of the foam blocks should only be flat;
• the layer of glue is applied in accordance with the instructions, do not exceed the thickness recommended by the manufacturer;
• the foam shrinks under the influence of direct ultraviolet rays, therefore, the joints should be sealed outside with cement;
• glue-foam is used only for the second layer of foam blocks. The first one should be applied to a cement-sand mortar, otherwise, under heavy weight, the glue will quickly deform.

Available in 750 ml cylinders.

Knauf

Knauf Perlfix glue provides a high level of adhesion thanks to a plaster base and special polymer additives.

The use of glue does not require preliminary installation of the frame, the work is carried out quickly, and the structure is stable.

The undoubted advantage of the composition is its environmental safety, therefore it is widely used in private housing construction.

The glue is quite economically consumed - for processing a coating of 1 sq. m. only 5 kg of composition will be required.

It is sold in kraft bags with packaging of 30 kg.

IVSIL Block

The glue of this manufacturer has been widely used when laying aerated concrete and aerated concrete blocks. The mixture is a dry powdery composition based on cement with a small content of additives that increase the adhesion of the surface.

It is used for joints from 2 mm, with this glue consumption will be in the range of 3 kg per m2.

When using glue, the position of the foam blocks can be adjusted within 15 minutes from the moment of fixation.

It is sold in bags of 25 kg.

Osnovit Selform T112

It is a frost-resistant compound intended for use in winter. The formed joints can withstand up to 75 freeze-thaw cycles without any problems - this figure is one of the highest among winter types of foam concrete glue.

The adhesive mixture is characterized by a fine filler fraction, due to which it is used to obtain thin joints from 1 mm. This leads to a decrease in the total consumption of the composition - only 1.6 kg of dry glue is required for pasting 1 m2 of foam blocks.

The advantage of the glue is its quick adhesion - the composition hardens after 2 hours, so that construction work can be carried out quite quickly.

It is sold in bags of 20 kg.

Among Russian manufacturers, the Rusean brand is also distinguished as having high quality and cost-effective products.

Material consumption dependence

The packages usually indicate how much glue goes to 1 cube of aerated concrete. When construction involves large volumes of work, the amount of material expended can significantly exceed the norms declared by the manufacturer. The difference can be very impressive in the consumption of glue for aerated concrete per 1 m3. But there are also the opposite situations. When calculating the required amount of the mixture, several factors must be taken into account:

1. Properties of the composition of the glue. The more fractional impurities in the mixture, the higher the need for a large layer. If the composition is based on adhesives and adhesives, then a minimum layer (2-3 mm) can be dispensed with.
2. Stacker qualification. The correct technique for using the bonding material greatly affects the consumption. Beginners often spend too much mortar on laying the gas block.
3. The presence of a layer of reinforcement. If a reinforcing layer is provided in the gas-block wall, then the consumption of the mixture will greatly increase.
4. Marriage of gas blocks. If you use a solution with a large amount of binders and the correct laying technique, and the gas block will have defects, then the consumption can increase significantly.

Masonry adhesive Kreps

If all standards are observed, the average thickness of the adhesive layer is 2 mm. By using the minimum joint thickness, the risk of cracking can be minimized. One bag of dry mix is ​​consumed for one cube of aerated concrete blocks.

You can count on spending not on volume, but on area. In this case, the consumption will be 1.5-1.6 kg per 1 m². Any physical impact is not terrible even with a thin layer of seams. Low temperatures and mechanical stress do not affect the final result.

Consumption of the mixture Insi-Block

This manufacturer produces not only ready-made mixtures for masonry, but also directly aerated concrete blocks. Mineral additives are added to the standard set of materials in the manufacture of glue. This makes it possible to increase the threshold for strength and adhesion. But it is possible to achieve high quality properties only if you apply the necessary layer provided by the manufacturer (thickness from 2 to 4 mm). Consumption of dry material - 28 kg per one cube of aerated concrete blocks.

These costs were calculated on the basis of a layer of 2 mm. If the thickness of the seam is increased, then the expense, respectively, will be the same. This mixture comes on the market in bags of 25 kg, so, for example, for 10 cubic meters of blocks, you need to buy 11-12 bags of dry glue. One bag requires 5-5.5 liters of water.If you follow this proportion, then the ready-made solution can be used within three hours.

Masonry mix Real

"Real" allows you to lay the gas block on a layer of 1 mm. With such a seam, the consumption per one cubic meter of the block is 21 kg of dry mixture. This glue is one of the most economical on the market at the moment. The quality of the masonry does not deteriorate because of this. It also allows you to save on plaster for wall cladding. The average layer thickness is reduced from 8 mm to 5 mm.

Assistance in choosing an adhesive

The question arises: what kind of glue is better to choose, and what should you pay attention to? This is what we are going to understand now.

Review of the most popular brands

The narrowly targeted adhesive for polystyrene concrete cannot boast of such a wide range as, for example, a composition for aerated concrete. However, there is still a choice. Moreover, there are universal compositions intended for lightweight concrete products in general, which can be easily applied in the case of laying a polystyrene concrete block.

As already mentioned, dry mixes of different brands differ from each other. Manufacturers strive to stand out from competitors, and for this purpose they focus on certain properties. In one solution there will be increased plasticity, in the other - its viability, and so on.

Let's use the table and consider some options for adhesive and masonry compositions in the form of dry mixes intended for laying polystyrene concrete.

Adhesives and masonry compounds from popular manufacturers:

Types of mixtures and their purpose

In total, there are two types of adhesive mixture: conventional compounds, the use of which is allowed at temperatures not lower than +5 degrees, and winter compounds, the use of which is permissible even at negative air temperatures.

Features of using glue with antifreeze additive are as follows:

• If the weather is warm outside, and you only have winter glue available, then it is quite possible to use it, and this will not entail any negative consequences. But the opposite is not worth doing.
• The presence of an antifreeze additive does not mean at all that styling can be done at absolutely any temperature. In severe frosts, work should be suspended. As a rule, manufacturers indicate a limit of minus 10-12 degrees. That is, these are the minimum temperatures.
• When using glue, the mixture is kneaded in small portions with the expectation that it will work out for about 20-30 minutes.
• It is recommended to use warm water.
• Block products should not be covered with snow or ice.

A house from a polystyrene concrete block can be built in winter

By using these tips, you will be able to avoid unpleasant consequences.

Execution of works

Before proceeding with the laying of polystyrene concrete blocks, the base is waterproofed with roofing material. It is recommended to lay it in two layers. Flaws on the foundation surface are eliminated with cement mortar.

1. The first blocks are installed in the corners of the building. A cord should be stretched between them, along which it will be easy to navigate during laying work.
2. The first row is put on a mortar of cement with sand, which you prepared yourself. This method helps to improve the level of adhesion and strength indicators of the building. In subsequent rows, special glue will be applied.
3. When the first row is laid out, it is reinforced with a special mesh.
4. Then the next rows are laid with the obligatory reinforcement of the seams. At least 20% of the seams should be offset.
5. To correct irregularities, no more than 15 minutes are allotted. For this reason, it is recommended to check more frequently. In the opposite case, it will be difficult to correct inaccuracies after the glue has set.
6. Jumpers are mounted in the openings intended for windows and doors, which can be purchased ready-made or made by hand. Homemade options are permissible only when building too narrow openings.
7. At the final stage of laying the last row, a reinforcing belt is mounted. This method will increase the strength of the structure and increase the seismic capacity of the entire building.

Differences between glue and cement mortar - the better it is

The technology for the correct laying of foam concrete differs from the methods of installing other wall materials, and cement mortar is poorly suited for its implementation. The thermal insulation properties of foam concrete blocks are higher than that of mortar, and thick layers of the latter make the structure blown and cold. When using this installation method, you will have to equip additional thermal insulation from the inside or outside of the wall.

The use of a special adhesive composition solves the problem. It forms a thin seam - durable, airtight and waterproof, so the room will be noticeably warmer. In addition, it is easier, faster to lay blocks on glue, it hardens more quickly, shortening the construction time. The cement mortar contains a lot of water, which immediately begins to be absorbed into the porous structure of the blocks, so you will also have to spend money on a water-repellent primer.

There are cases when it is still possible to lay blocks on a regular mortar:

• material size - about 30 cm;
• incorrect geometry of products;
• deviations in height - more than 1.5 cm;
• the presence of chips.

In other cases, it is better to purchase an adhesive composition, especially when the size of the foam blocks is up to 100 mm.

S-26 glue for porcelain stoneware

It is used for gluing porcelain stoneware tiles, marble, composite stone on various surfaces. Consumption 1.5 - 1.6 kg. dry mix for 1 m² with a layer of 1 mm.

All those characteristics that porcelain stoneware possesses can be realized only with its correct installation.

Conversely, if the installation of porcelain stoneware is done with errors or incorrectly, then the tiles will begin to lag behind the surface and collapse with minimal impact on it.

An important, if not the main, role for obtaining a good result from the use of tiles is played by the used glue C-26 for porcelain stoneware.

• Water and frost resistant
• Highly adhesive
• Elastic
• Reinforced fixation
• Has increased durability
• For interior and exterior use

Application area

It is used for gluing porcelain stoneware tiles, marble, composite stone on various surfaces.
It is applied on concrete, stone surfaces, bricks, plasters, gypsum boards, drywall. Possesses high adhesion and increased strength. For interior and exterior use.

Surface preparation

The base for the cladding must be strong, not subject to shrinkage or deformation, free from dirt, dust, oils, grease and all types of paints, as well as flaking elements. Cement-based surfaces with high water absorption must be moistened before gluing.

Mortar preparation and application

To prepare the mortar mixture, an accurately measured amount of pure water is taken. The dry mixture is gradually added to water with stirring, achieving a homogeneous mass without lumps. Mixing is carried out using a mixer or a drill with a nozzle for viscous mortar mixtures at a rotation speed of 400-800 rpm. Then maintain a technological pause for 5 minutes to ripen the mortar mixture and mix again. The mortar mixture should be consumed within 2 hours.

It is applied in a thin layer, which increases the thermal insulation characteristics of the masonry. Not afraid of low temperatures, suitable for all types of aerated concrete.

Composition for masonry blocks from aerated concrete K21 / 1

This type of masonry compound is a dry mortar made of cement, quartz sand, polymers and minerals. It is diluted with water, forms a plastic mixture with good adhesion characteristics, after hardening, it calmly withstands a large minus and exposure to moisture.

The glue is used for laying aerated concrete blocks with a clear shape and size, since the seam thickness is 2-3 millimeters. The mixture can be used for the installation of expanded clay concrete blocks, other materials, it is ideal for eliminating small defects on the surface inside and outside the building.

Mounting adhesive has all the advantages of this type of compound.

The dry mixture is diluted with water in a ratio of 4.5: 1, mixed at low speed with a stirrer, settled for 10 minutes, then mixed again and used for a maximum of 2 hours. It is applied with a notched trowel on the surface at a temperature of + 5-25C, on a solid and even, always clean, slightly damp base.

Blocks are adjusted quickly, with a hammer within 5 minutes after laying. Excess mortar is removed with a trowel, the thickness of the seam should be a maximum of 3 millimeters. The consumption of the mixture is approximately 25 kilograms per 1m3 of blocks. Installation is best done in dry conditions, at a temperature of + 5-25C, the final hardening occurs within a day.

Instead of a conclusion:

Mounting adhesive for aerated concrete today is considered the most preferred option when choosing a mortar for masonry. Simple preparation, minimal joint thickness, easy and fast work, high quality of the joint, increased thermal insulation properties and a host of other advantages fully justify the cost of the mixture and make it an ideal choice for high-quality modern construction.

Glue mixture solution preparation technology

The preparation of the working solution is carried out according to the instructions of the manufacturer of the dry concentrate. The general steps and principles for preparing an adhesive mixture include the following points:

• to prepare the solution, use a container of the appropriate volume and a drill with a mixer;
• measure the required amount of dry mix and water as indicated in the manufacturer's instructions. As a rule, the proportions are on average 1: 0.22, that is, 220 g of water is taken for 1 kg of dry concentrate;
• the range of water temperature for the solution is from +15 to + 60 ° C;
• knead the mass until smooth, then let the solution settle for 10-15 minutes and mix thoroughly again.

The solution is mixed in portions in accordance with the intensity of work on laying aerated concrete. The service life of the working mixture is about 3-4 hours, but this figure may vary depending on the brand, working conditions and other design factors. It is not allowed to add water to the finished solution, while the glue should be periodically stirred during operation.

It should be borne in mind that the consumption of glue for gas silicate depends on a number of factors, including:

• block geometry and surface defects;
• the presence of reinforcing elements;
• characteristics of the tool for applying the bonding agent;
• temperature and concentration of the solution;
• weather conditions and qualifications of the master.

The formula for the consumption of the adhesive solution looks like this: S = [(l + h) / l * h] * b 1.4, where:

• S - consumption of 1 kg of the mixture per 1 m³ of the base;
• l, h - dimensions of length and height in m;
• b - seam thickness in mm;
• 1.4 - conventional value of the consumption of dry concentrate in kg / m² with a thickness of the bonding layer of 1 mm.

In order to carry out the construction of walls made of porous concrete with the highest quality, it is necessary to use adhesive mixtures taking into account their purpose: for indoor or outdoor work, for laying gas silicate at positive or negative ambient temperatures

It is also worth paying attention to the setting speed of the working solution, this parameter varies from 5 to 25 minutes, depending on the brand of product

In this case, the minimum period of solidification of the adhesive base in a block structure is 24 hours, and for the final result, a period of at least three days is required after installation.
