Building a house from any material is troublesome and slow. Previously, in addition to technological needs, it was necessary to interrupt the period of winter cold. Modern technologies make it possible to construction works all year round, but subject to simple requirements:
- calculation of materials and sequence of work, taking into account low temperatures;
- providing the construction team with a heated utility room;
- bringing additional lighting to the site (taking into account the short winter day).
At the heart of the foam block - cellular concrete brought to a foamy state. Lightweight porous material, with good soundproofing and heat-saving characteristics, practically does not shrink the walls.
But foam blocks have a high rate of moisture absorption. Air pores during freezing of water from low temperatures relieve internal stress, which makes foam concrete frost-resistant (up to 35 freeze / thaw cycles). It remains only to ensure that the ends of the blocks are covered, and water does not get on the surface, which can destroy the top layer.
AT winter conditions for foam blocks, the composition of the solution or adhesive mixture is more significant. The basis of the mortar is cement, which begins to lose its properties at 5 0 C, and is completely unsuitable already at -5 0 C. It is important that before these temperatures the mortar gain at least 30% strength, then it will be able to resist loads. Further strength gain will occur after thawing, and if before this time the foam block is loaded beyond the permissible limit, the solution will not withstand and will crumble. Note that "heating" additives in concrete are designed to speed up the process of gaining just these 30%, and not all possible strength.
The way out of the situation can be the erection of a frame-film tent over the building and the use of special glue for mounting foam blocks. Additives and additional structures increase the winter construction budget.
A house made of foam blocks requires insulation and outer cladding. For any type of insulation, it is important that during the installation process it does not pick up moisture from the air. Any hinged systems(siding, porcelain stoneware) are not afraid of low temperatures. Only with a “wet plaster” finish will have to wait until the onset of heat.
As for houses made of foam blocks, strength brickwork depends on the quality of the connecting cement mortar. During operation, the temperature of the heated by chemical means cement must be at least +5 0 С (heating is not allowed hot water– cement loses its quality). Another option is the freezing method, when rubble concrete is used (heated up to +2 0 C) and high rates work. This is necessary so that even before freezing, the seams are sealed under the weight of bricks from the upper rows. It is important that during the laying process, the bricks are cleared of ice and snow.
Installation features truss system and styling roofing materials does not exist. There are only a few types soft roof that do not withstand low temperatures at the time of laying. Such tiles are heated to soften the bitumen and glued according to the technology.
During the winter construction holidays, the developer is more likely to find a free team of high-quality masons who will work without undue haste, looking back at the next object (even taking into account breaks for very very coldy and snowfalls). In addition, in winter, almost all building materials are sold at large discounts, and their choice is much larger.
If the building site is located in an uninhabited area, then in winter time especially acute is the issue of protection of imported materials. If there is no possibility of phased delivery, then someone should always be present on the site. For transporting materials or approaching the site, for example, concrete mixers, a frozen winter road is much more convenient.
Features of building a house from gas blocks in the winter.
The features of aerated concrete blocks include them high ability absorb moisture and relative brittleness. If during the thaw period blocks of aerated concrete are saturated with water, then when they freeze, they are completely covered with mini-cracks. Therefore, during the winter construction period, during a thaw or rain, the entire building of gas blocks must be waterproofed.
If it is planned to install a concrete interfloor ceiling in a house made of gas blocks, then it is necessary to build reinforced belt. The process uses a large number of concrete, which means that requirements are set for it on the appropriate brand and the use of chemical reagents that delay solidification.
The gas block collapses over time under the influence of precipitation, therefore, finishing of facades is necessary. But the blocks from the manufacturer most often come raw, and they require a long drying time. Then the building is covered with a roof and left to settle and dry for up to a year. In addition, in the case of gas blocks, it is recommended that you first perform interior decoration so that all moisture evaporates from the blocks to the outer cladding.
Aerated concrete - not best material for winter construction, and if it is nevertheless selected, then blocks are needed high brand, and for laying it is best to use "warm" concrete.
The use of ceramic blocks in winter construction
Like any other material from the category of "building stones", ceramic blocks very frost-resistant (up to 50 freeze / thaw cycles). But for their laying, a cement mortar is also needed with its requirements for speed and pour point. Convenience consists in the presence of a tongue-and-groove system for a more dense connection of blocks in a masonry without the use of a mortar (only horizontal seams are connected with a mortar). Besides, in recent times widespread special adhesive solutions for ceramic blocks, laid on the surface of the block, do not fall into its holes and do not require a full-fledged seam.
If, nevertheless, a cement mortar is used, then it should be “warm”, with pumice, sand or perlite fillers. It will cost more, but energy efficiency finished house the result will be higher.
Keramoblock is a very young material (it is about 30 years old), so it has not yet been possible to test it for durability. And here thermal insulation characteristics already explored. If a block 38 cm thick is used in construction, then such a wall does not require insulation. For more thin walls enough plaster, but it can only be carried out in warm time of the year.
Manufacturers of ceramic blocks still do not recommend laying walls from this material if the air temperature drops below +5 0 C.
Winter construction from wood
This is perhaps the only material that has a lot of advantages in the winter version of the building.
A tree harvested in winter contains less moisture, which means it is not affected by mold and decay, and there are no active insects in it. The drying process has been replaced by a uniform freezing process, and until spring (thaw) the tree retains an acceptable percentage of moisture (12-20%). dried in this way wood material more durable and no cracks.
During the production of rounded logs and various kinds timber, they are covered with impregnations that protect against fire, moisture and rodents. But after the construction of the walls, the impregnation must be repeated. With winter construction reprocessing it is better to postpone until the onset of heat.
Shrinkage period wooden houses different, but for glued laminated timber, for example, it is minimal (about 2 months), so a house built in winter must be finished in late spring - early summer. For log cabin shrinkage may take up to 12 months.
Carpenters prefer to build wooden houses in winter, also because in frost it is easier to cut corner locks, and when a thaw sets in, the tree swells and dries, their geometry does not change and much fewer cracks appear.
Wood is a living material that rots when exposed to moisture. Therefore, if wooden material brought to the site in frost and will lie there for a long time, it will take reliable protection from getting water in the thaw or rain.
Building a house from sip panels in winter
Houses from sip panels are construction based on wooden frame and particle-oriented boards. Its construction does not require the so-called "wet" processes (cement mortars and plasters). Even the foundation for such houses can be piled, which does not require pouring mortar. Houses are going to construction site from factory blanks that correspond to the dimensions and layout of the house, like a designer.
In frosts, construction is distinguished by the use of "winter" polyurethane foam and well-frozen, and therefore more durable, wood (in the summer, in the heat, the frame can dry out). Even if a tree with a moisture content of up to 30% is used for the frame, it will have time to give off enough moisture during construction to meet the norm. In winter, there is less precipitation in the form of rain, and there are more chances to build walls and cover them with a roof without wetting the structure.
A house made of sip panels does not shrink, therefore Finishing work(especially internal) can be started immediately after the completion of the main construction. In winter, workers will bring less dirt into the room. If for external cladding (mandatory for frame houses) hinged technologies (not plaster) will be used, then they can also be carried out before the start of the active construction season. This will significantly save on the purchase of materials.
If the foundation under the sip panels is laid in the fall, the house is built in the winter, then by the beginning of the summer it will be possible to move into it!
Winter construction from wood concrete
Arbolit is a wood concrete, therefore all positive traits wood, reinforced positive properties high quality cement.
For private construction, blocks are used that have good bearing and thermal insulation properties, where a wall of 30 cm without insulation replaces a brick one, but 1 m thick. Bearing in mind that "cold bridges" are located in the places of interblock joints, it is better to use special mixtures based on expanded perlite when laying.
The chips included in the arbolite conifers wood and chemical additives provide this material with good frost resistance.
The speed of building walls from wood concrete is very high, but when purchasing material, it is necessary to purchase halves of blocks (it is difficult to cut wood concrete). In 1-2 months, the house will be ready, which, in the winter version, will not allow the wood concrete blocks to gain excess moisture.
When finishing a house from wood concrete, it is important to “catch” such a moment when the blocks in the masonry dried out, did not have time to be saturated with spring moisture, and you can perform outdoor facing works. This is because for finishing you need to use plaster or decorative concrete having a good coupling with wood concrete. And such work is performed only in the warm season.
While talking about winter construction from various building materials, we did not touch on one important point: laying the foundation. The opinions of experts are unanimous that it is best to mount it in the fall, when the soil is softer, and the conditions are most favorable for gaining full concrete strength. Of course, depending on the composition of the soil, for frame, foam concrete or gas-block houses, it is possible to build a pile (with varieties) foundation, which does not require concrete mixing and certain temperatures for strength gain. Pile and monolithic slab foundation can be installed on frozen ground. But laying a deep-seated tape requires digging a trench in frozen ground, insulate formwork and pour heated concrete, and this is an additional investment of labor and finances.
From our review, we can conclude that buildings can be made from any building material in winter. Wood and its derivatives are most suitable, but ceramic blocks and gas blocks “prefer” the warm season.

Features of construction in winter from aerated concrete blocks
Ytong or Gras (st. No. 2)
Questions about winter construction
SPECIALLY FOR LAYING INTERNAL PARTITIONS, Xella Ytong Launches New Product Sale" Polyurethane adhesive for aerated concrete Ytong Dryfix 750 ml". On this page you will find the presentation of the new product.
October is the month which is popularly called the pre-winter month, that is, the calendar period when frosts begin to set in. And the presence of frosts and subsequent frosts, impose certain features when performing masonry walls from Ytong aerated concrete blocks of the Mozhaisk Ytong aerated concrete block plant or Maloyaroslavsky Gras aerated concrete block plant. The peculiarity of masonry from Ytong aerated concrete blocks in winter is that it is no longer possible to work using Ytong summer glue during this period, for laying Kaluga aerated concrete blocks or Ytong aerated concrete blocks in winter, Ytong winter glue or polyurethane glue is needed
The basic requirements for laying aerated concrete blocks Yitong in winter are set out in the SNiP for stone and reinforced masonry structures and SP 1513330 2012 in the section "Instructions for the design of structures erected in winter" Yitong, aerated concrete bearing walls and partitions both during their construction in winter and during their subsequent operation. I.e main criterion assessment of masonry quality aerated concrete walls from Ytong aerated concrete blocks in winter to Ytong winter glue (I want to emphasize again) or to polyurethane glue , this is to ensure the design strength of aerated concrete walls made of Ytong aerated concrete blocks or Gras aerated concrete blocks laid out on Ytong winter glue or polyurethane glue Ytong Dryfix and their stability during subsequent operation.
The strength of laying aerated concrete walls from Ytong aerated concrete blocks in winter with Ytong winter glue depends primarily on the ability of Ytong glue or mortar at low temperatures and in conditions of ice and snow to provide:
1- Reliable adhesion of Ytong aerated concrete blocks in the process of laying an aerated concrete wall in winter with Ytong winter glue or polyurethane glue between each other and thereby create a monolithic aerated concrete wall from purchased Ytong aerated concrete blocks or Gras aerated concrete blocks.
2- A set of necessary, according to the Ytong strength project, on which Ytong aerated concrete blocks are laid in the winter in the aerated concrete wall of the cottage.
Now knowing what needs to be provided with the use of Ytong winter glue, in the process of laying aerated concrete walls from Ytong aerated concrete blocks in winter or Grasse aerated concrete blocks in winter, let's move on to considering the provision of conditions for laying aerated concrete blocks in winter.
And so what prevents in winter conditions at low temperatures to ensure proper adhesion between or Gras when they are laid in the aerated concrete wall of the cottage in the winter with Eatong winter glue or polyurethane glue Ytong Dryfix
1-since the surface temperature of Ytong aerated concrete blocks or aerated concrete blocks Kaluga aerated concrete or Gras aerated concrete block is negative, then the hit of a solution or glue Itong closed on water to the surface forms an ice film that prevents the liquid phase of Ytong glue or solution from penetrating into the surface zone aerated concrete block Ytong, as a result of which the gluing of the surfaces of aerated concrete blocks of Ytong with Ytong glue does not occur. Therefore, in order for the ice film from Ytong winter glue not to form on the surface of the Gras aerated concrete block or Ytong aerated concrete block, small amounts of salt additives, usually sodium nitrate, are introduced into the Ytong winter glue or winter adhesive solution, which, by lowering the freezing point of the water located in Yitong glue, as a component of the glue or solution, does not allow the formation of an ice film and the liquid phase of the winter glue or solution freely penetrates into surface layer aerated concrete blocks Ytong or Gras, providing physical conditions gluing the surfaces of aerated concrete blocks Itong or Gras into a monolithic aerated concrete wall of the house. To date, there is no need to make a mortar or adhesive with antifreeze salt additives in the construction conditions on site. Factories today produce special winter adhesives for aerated concrete blocks Yitong and Gras, which allow laying aerated concrete walls from aerated concrete blocks Yitong or Gras on winter glue at air temperatures up to -15 0 C. Polyurethane adhesive does not have such disadvantages even at negative temperatures down to -5 aerated concrete blocks Yitong can be carried out in winter.
1.1-The adhesion of Ytong and Gras aerated concrete blocks is not ensured when laying aerated concrete walls of cottages, even when using Ytong winter glue or winter mortar, if there is snow or ice on their surface, therefore, when laying aerated concrete walls from Ytong or Gras aerated concrete blocks during masonry work on Ytong winter glue, it is advisable to cover aerated concrete walls from precipitation on their surface. And if snow has fallen on the surface of Ytong or Gras aerated concrete blocks, then before laying Ytong aerated concrete blocks on Ytong winter glue, it must be carefully removed. An important role is also played by the correct Itong or Gras during the period of preparing them for laying in aerated concrete walls.
2-The strength and solidity of the aerated concrete wall of the cottage, laid out from Ytong aerated concrete blocks in winter or Grasse aerated concrete blocks in winter, is directly affected by the strength of the winter glue itself or the winter adhesive solution. let's get a look physical and chemical process occurring in the adhesive or mortar mass during its mixing with water. The basis of winter mortars and winter glue Itong is cement. Cement is able to hydrate, followed by crystallization and formation cement stone only in the presence of water in the liquid phase. And in order for this to happen, and the winter glue or winter adhesive solution at negative temperatures could gain strength, it is necessary that the water be in the liquid phase, and this can be achieved either by introducing the same salt additives that exclude water freezing in the winter glue or winter solution, or by heating the aerated concrete wall itself, providing it with a positive temperature. The solutions are different - this is the arrangement of the so-called "greenhouses" or the use of electrical heating of the masonry of aerated concrete walls from aerated concrete blocks Itong or aerated concrete blocks Gras. There are technologies that allow the so-called laying of aerated concrete blocks for “freezing”, when the wall built is not loaded before the onset of positive temperature, the gas block is warmed up, winter glue or winter mortar is warmed up, a liquid phase of water is formed, which provides adhesion in the final process aerated concrete blocks and curing of winter glue or winter mortar over time. But here, in this case, it must be remembered that the laying of aerated concrete walls for freezing is special technology stone works, aerated concrete wall built using this technology is not loaded until the aerated concrete walls are completely thawed, and after that, at a positive temperature, on average, about a month, the aerated concrete wall of the cottage, laid out on winter glue from aerated concrete blocks Itong or aerated concrete Gras blocks, is cured. An aerated concrete wall built on Ytong winter adhesive, at the end of the month, is subjected to laboratory strength tests, and only when the design strength is gained, an aerated concrete wall made of Ytong or Gras aerated concrete blocks built on Ytong winter adhesive can be loaded with loads, lintels, beams, ceilings, etc. d. During the winter laying for “freezing” on Ytong winter glue, it is necessary to carry out engineering measures to exclude the loss of stability of aerated concrete walls until they reach the required design strength.
AT winter period it is forbidden to use masonry winter mortars and winter adhesives with antifreeze additives of a brand less than M-50 and for freezing with a brand of less than M-100 during the construction of aerated concrete walls from aerated concrete blocks Yitong or Gras.
The height of aerated concrete walls made of Yitong aerated concrete blocks or Gras aerated concrete blocks erected on glue for “freezing” should not exceed 15m or 4 floors.
It should also be taken into account that in aerated concrete walls built from Yitong aerated concrete blocks or Gras aerated concrete blocks on Yitong glue using the “freezing” technology and already hardened when collecting loads and transferring them to such a wall, the coefficient. The working conditions of such a wall cannot be more than 0.7
Considering that it is rather difficult to prepare glue or mortar with antifreeze additives in construction conditions, hence my advice is to use winter adhesives and winter mortars produced in the factory and by companies with a good reputation from the distributors of these companies.
Laying aerated concrete in winter is accompanied by some difficulties, inconveniences and additional costs. But not everything is so scary, you can handle it. Let's start with the fact that it is better to start laying after all in the spring, when there are more daylight hours and there are six months of warm days in stock. But what if you still have to build from aerated concrete in winter?
The construction site must have electricity for heating, warm water, frost-resistant adhesive for masonry, good source lighting and film, which is needed to cover and warm up aerated concrete blocks. As you understand, due to additional measures related to the heating of materials, the speed of construction is slowing down.
But, in winter, building materials do good discounts Moreover, many builders sit without work in the winter, which increases competition between builders, and they can also make a discount on their work.
At negative temperatures, a special frost-resistant glue must be used for masonry, which is suitable for work at temperatures down to -15. But still, we would not recommend you laying at temperatures below -10.
The cost of glue for winter masonry is only 10-20% more expensive than usual. Differences of winter masonry adhesive in antifreeze additives: special salt and other components that prevent freezing of water in the adhesive at low temperatures (up to -15).
Glue needs to be prepared only in plastic container with a lid, and the water must be used heated, with the maximum allowable temperature written in the glue instructions.
Aerated concrete blocks to be glued together must be thoroughly cleaned of snow and ice, and they must also be warmed up.
Tightly cover the pallet of gas blocks with a fire-resistant film or banner, press the ends of the film so that the heat does not escape, and heat the aerated concrete with fan heaters or heat guns. The warm-up time depends on the power of the warm-up itself, and on the temperature environment. We recommend doing a warm-up of high quality.
Note that insufficient heating of aerated concrete reduces the strength of adhesive joints, which is explained by the crystallization of water in the pores of aerated concrete. Be sure to use frost-resistant glue and warm up the aerated concrete normally.
- Rows of blocks are carefully cleared of snow and ice.
- Masonry blocks are preheated.
- For masonry, use only frost-resistant glue.
- Glue mixing takes place only in plastic container with lid.
- Glue is kneaded with hot water (up to 60 degrees).
- Winter adhesive mixtures should be developed as quickly as possible, within twenty minutes.
- The temperature of the finished glue should be from 10 to 20 degrees.
- For reinforcing the strobe and masonry of the first row, a conventional solution with antifreeze additives is used.
In the case of long-term storage of gas blocks in winter, you need to keep them closed in their original packaging. If you plan to lay aerated concrete in the winter in the near future, then it is advisable to remove the side of the package so that the blocks dry out. Fresh factory aerated concrete comes out of the autoclave wet. The upper part of the blocks must always be covered from rain and snow.
If you talk about conservation briefly, then you need to close the entire upper part masonry, including window sill areas.
For more information about this issue, see the video from Gleb Green - the main Russian specialist on aerated concrete.
Is it possible to build a house in winter time?
The construction of a private house is a complex process, the duration of which depends on many factors. Construction, which is not always started in the spring, can be completed before the onset of cold weather. Many developers are interested in whether it is possible to build a house in winter. They do not want to stretch the execution of work and at the same time are afraid to make a mistake. Thanks to modern technologies It is possible to build buildings all year round.
Construction in winter - general specifics of work
Crystallization of water entering concrete is a major problem during construction in winter. Without application modern methods and the use of modifiers, moisture increased in volume can violate the integrity of the concrete mass.
Regardless of whether brick blocks are used to build a house or concrete is used, the following conditions must be observed:
- stick to technological recommendations to perform work in cold weather;
- provide a heat-insulated room for construction personnel;
- provide a level of illumination that allows you to work after dark.
Despite the seasonal nature of construction work, winter is not an insurmountable obstacle to their conduct.
The general algorithm for erecting a building in cold weather, regardless of the materials used, includes the following stages:
- obtaining permits. Registration of a building certificate is in no way connected with the time of year. You just need to develop a project in a timely manner and submit the necessary documents for registration;
- purchase and delivery to the site necessary materials. Costs will be significantly lower due to seasonal discounts. Transportation of materials in winter can be much easier, as the mud will not interfere with the access of vehicles;
- performance earthworks associated with the arrangement of the foundation. The negative temperature facilitates work on loose soils. The use of concrete with additives allows you to pour the foundation at temperatures up to -20 ⁰С;
- erection of capital walls and construction of the roof. In the construction of load-bearing walls and partitions, heated mortar or concrete composition with the addition of plasticizers. AT wooden bars used in frost to build a roof, the concentration of moisture is maximally reduced;
- roofing and finishing works. Not all roofing and Decoration Materials allow them to be used at sub-zero temperatures. To perform work in the winter, you should choose the right materials.
To use concrete at low temperatures, modern methods can be applied:
- enter into concrete mix additives that increase the frost resistance of the composition. This will allow construction activities to be carried out low temperature;
- preheat the concrete at the stage of its preparation. After pouring, the solution must be thermally insulated so that it completely hardens before the water freezes;
Most of the problems associated with winter construction are caused by the property of water to freeze at temperatures below zero degrees.
- perform electrode heating by passing current through steel electrodes. The supply voltage is supplied from a step-down transformer;
- use infrared sources. They allow you to perform directed heating of the array, as well as increase the temperature of the concrete through the formwork;
- use heating cable. It is laid in loops with an equal interval between turns before concreting, and heats up the concrete solution when voltage is applied;
- install heating formwork. It consists of standard sections, which are equipped with electric heaters and easily combined into a single structure.
Using these methods, it is possible to provide the necessary conditions of the concrete solution.
Winter construction - pros and cons
Carrying out concrete activities in the winter, you can appreciate the following advantages:
- conservation of the landscape. At low temperatures, it will not suffer as a result of the movement of construction equipment on frozen soil;
- ease of delivery of building materials. Durable and dry pavement and the absence of thaws provide the possibility of accelerated transportation;
- significant savings. The cost of building materials in winter is much lower than in the rest of the time;
- reduction in work time. Building a box in winter will allow you to quickly start finishing with the onset of spring.
erection residential buildings has a number of specific requirements that prohibit certain types of construction work in winter
Along with the advantages, there are weaknesses:
- additional costs associated with the use of plasticizers and increased power consumption;
- the need for professional equipment to warm up and attract specialists;
- reduced daylight hours and adverse weather conditions that adversely affect the pace of work.
On the concrete examples Consider the possibility of using various materials at low temperatures.
Is it possible to build a house in winter from foam blocks
Foam blocks - a variety porous concrete. They are characterized by increased operational characteristics: heat-saving properties, high sound insulation, do not shrink. However, foam blocks have increased water absorption, to prevent which it is necessary to protect the surface.
In winter, you can put foam blocks. It is important to consider the following points:
- use a mortar or adhesive with frost-resistant characteristics;
- erect a tent-type frame-film structure above the masonry;
- protect the surface of the blocks from moisture with the help of external cladding.
These measures increase the construction budget.
Masonry blocks should not be damp and covered with snow
Can it be glued on?
It is very important to carry out the arrangement of the foundation base during the summer period, which must necessarily completely harden before the onset of the first stable frosts. Only in this case can winter masonry technologies be successfully applied.
You can perform laying in the frosty season, following certain rules.
Low-temperature conditions can complicate construction work that is associated with the hardening of cement mortars, therefore, in the cold winter period, it is necessary to warm up aerated concrete, as well as use special antifreeze additives. Experienced specialists in the construction industry recommend combining the use of chemical and physical ways protection with work on warming up stacked blocks and mortar.
Using Winter Glue or Additives
The standard consumption rates of such an adhesive with a thickness of 0.2 cm are significantly reduced compared to conventional cement mortar for optimal thermal conductivity.
Qualitative winter glue is characterized by high adhesion and moisture resistance, and also has frost resistance, therefore it can be used in the process of puttying and for leveling the surface.
The adhesive is based on Portland cement, as well as fine-grained sand. Feature is the addition polymer additives, improving gluing abilities and plasticity indicators, as well as modifiers that minimize the risk of cracking. 
Peculiarities
Winter adhesive mixtures in conditions of negative temperatures should be used in the first thirty minutes after dilution with hot water at 60 ° C. Properly prepared adhesive should have a temperature of 10-20 o C. On blocks adhesive composition applied with .
Attention!
Laying in frost involves the mandatory cleaning of aerated concrete from snow mass and ice. Also, the blocks must be preheated.
For this purpose, it is necessary to build a frame base around the pallet with building material, cover the frame with a film or a refractory awning, and then warm up with the help of heating elements or a heat gun. It should be noted that insufficient or poor-quality heating of aerated concrete sharply reduces the final indicators of the strength of the joints, which is caused by the crystallization of water, which accumulates in the pores of the building material.
Summing up:
- When laying in frost, it is imperative to use winter glue for aerated concrete or anti-frost additives in ordinary glue.
- The adhesive mixture is diluted with hot water strictly according to the instructions, which must be read on the package.
- Blocks need to be warmed up immediately before laying.
placed on cement-sand mortar, in which special antifreeze components must be added in winter.
When making for floors in winter, antifreeze additives should also be added to concrete.
Up to what temperatures can you work?
Not all antifreeze additives produced today by domestic and foreign manufacturers, correspond to GOST 24211-2003.
High-quality winter glue for the construction of aerated concrete walls allows you to carry out construction work in conditions temperature indicators down to minus 10-15°C.
With the same indicators, you can use masonry mixtures intended for the construction of walls of aerated concrete in conditions low-rise construction at negative temperatures. 
The use of standard, or so-called "summer" masonry mixtures with the addition of the antifrost additive "Antimoroz" allows you to perform construction work with a guarantee up to a temperature of minus 15°C.
Not too noticeable increase in the cost of winter construction due to the purchase of special additives and adhesives can be offset by a seasonal decrease in prices for aerated concrete blocks.
