Laying aerated concrete (gas block) in winter on glue – is it possible to build a house in winter

It may seem impossible to build a house in the winter, especially if you have to deal with materials like gas blocks, or aerated concrete blocks. Because they are lightweight and have excellent insulation qualities, these blocks are commonly used in construction. However, how does the cold weather impact the laying of these blocks, especially if adhesive glue is being used?

The difficulties of winter building include subfreezing temperatures and moisture, which can affect the build’s longevity and quality. There are extra risks when using glue to join aerated concrete blocks in the cold. If the temperature drops too much, the adhesive may not set properly, endangering the walls’ structural integrity. However, building can be done safely and effectively in the winter with the right supplies and precautions.

Even in freezing temperatures, working with aerated concrete blocks is possible thanks to modern construction methods and specialized winter adhesives. Building professionals can guarantee solid joints and a robust structure by selecting a glue type that is appropriate for cold climates and adhering to strict instructions. In order to overcome the difficulties of winter construction and enable year-round building projects, careful planning and preparation are essential.

The practicalities of installing aerated concrete blocks in the winter will be discussed in this article, with an emphasis on the usage of adhesive glue. Regardless of the season, we’ll go over the essential safety measures, suggested supplies, and professional advice to help you complete a successful build. Whether you’re a do-it-yourselfer or a professional builder, knowing these factors is essential to building a sturdy and well-insulated house that will withstand any type of weather.

It is possible to build a house with aerated concrete (gas block) and adhesive during the winter, but there are some things to keep in mind. If the right safety measures are followed, like using winter-grade adhesive and making sure the blocks are dry and frost-free, this method should work. Furthermore, it’s important to carefully monitor working conditions like temperature and moisture control to avoid issues with the concrete setting and losing its insulating qualities. Aerated concrete construction in the winter can be a feasible option if the proper planning and supplies are used.

Advantages and disadvantages of winter construction

1. In winter, building materials are sold at a reduced cost (up to 15%).
2. Reduced prices for construction work.
3. When delivering blocks, construction equipment will not damage access roads, no costs will be required for restoration work on the site.
4. Safety of masonry and the ability to control the quality of installation of blocks, since.. the pace of work is lower than in the summer.

• difficulties in storing blocks;
• the need for heat treatment of blocks;
• reduction in the speed of masonry due to unstable winter weather conditions;
• the need to use a more expensive adhesive base and additional fixing materials.

Features of masonry in winter

When determining whether a house made of aerated concrete can be built in the winter, experts permit block construction in extremely cold temperatures.

1. It is necessary to clean the blocks from ice and snow.
2. The building material is heated with a heat gun, fan heater.
3. The adhesive composition is applied to aerated concrete with a trowel.
4. It is recommended to arrange a utility block with temporary heating next to the construction site, leave materials in the room, dilute the glue.

Permissible temperature

It is advisable to consider the GOST-permitted parameters when determining if laying blocks at subzero temperatures is feasible. It is possible to lay at -10…-15 °C if you are using a good adhesive base.

Examining adhesive mixture compositions and adding anti-freeze components is crucial. Work cannot be done below -15 °C due to the possibility of seam cracks and structural deformation.

Tools

• electric drill with a set of attachments or a construction mixer;
• mixing utensils;
• brushes for cleaning blocks;
• hacksaw for cutting blocks;
• ladle;
• perforator;
• plumb line;
• spatulas;
• rubber mallet for leveling the structure during installation;
• building level, etc..

Choosing glue and additives

Winter glue is more resilient to freezing temperatures, moisture, and adhesion. The substance is utilized for filling and leveling coatings. Portland cement and fine sand are usually the ingredients of the adhesive base. Additives made of polymers are used to make the composition more malleable.

Modifiers aid in preventing surface cracks and deformations in the blocks. The glue base is laid in a thin layer that is 2-3 mm thick. The glue’s frost resistance should come from the F50, and 20 days after laying, the clutch density should be at least 0.51 MPa.

The composition needs 40–60 minutes to cure. The mixtures must be diluted with heated water before use; they are sold as powders.

How to warm up gas blocks in winter

It is essential to tightly cover the products with a film that has fire-resistant properties in order to warm up gas concrete blocks. To stop heat leaks, the film’s ends are pressed together. Next, heat guns and heat ventilation systems are used to heat the building materials.

The weather has an impact on the processing time. The strength of the adhesive joints and the dependability of the structure can be compromised by inadequate heating of the blocks.

How to store blocks in winter

In the winter, blocks need to be stored properly. Goods have to be sealed and kept in a closed space. Precipitation protection of the upper portion of the gas concrete products is crucial. The side portion of the package must be removed one day prior to use in order for the blocks to dry.

The process of laying blocks

1. The blocks are cleared of ice and warmed up.
2. The adhesive solution is mixed in a plastic container using heated water (up to +60°C).
3. When laying, an adhesive base with a temperature of +10…+20°C is optimal.
4. Installation must be carried out promptly at sub-zero temperatures to prevent the structure from freezing.
5. To strengthen the structure, the first row of masonry and grooves can be reinforced using reinforced mortar.
6. When performing masonry in stages, it is necessary to check the strength of the wall panel built the day before. It is necessary to tap the wall with a rubber hammer. If there is no damage, you can complete the work on laying the blocks.
7. It is necessary to monitor the temperature of the adhesive mixture, which should not drop to 0°C. To do this, it is necessary to close the container, prevent overcooling of the composition, heating the mass.

Tips for preserving a house made of aerated concrete blocks

1. It is not recommended to stop construction work without floors on the ground floor.
2. External walls must be protected with finishing slabs until sub-zero temperatures set in.
3. Experts do not recommend leaving the building without a roof. However, if necessary, you can cover the wall panels with polyethylene by securing the sheets at the bottom.
4. The floor is insulated with straw mats. Window and door openings are covered with roofing felt or sheets of plywood.

It is not only feasible, but also feasible to construct with aerated concrete blocks, also known as gas blocks, during the winter with the appropriate strategy. Using a specific winter adhesive that is made to function in cold temperatures is one of the most important factors to take into account. This kind of adhesive helps to preserve the building’s structural integrity by ensuring a solid bond between the blocks even in cold weather.

Temperature control is another crucial factor. Monitoring the temperatures of the materials and the surrounding air is essential. Prior to use, materials such as adhesive and blocks should be kept in a warm, dry location when working in the winter. Furthermore, shielding the building site from inclement weather by using tarps or tents can help safeguard both the workers and the structure.

In the end, using aerated concrete blocks for construction in the winter demands meticulous planning and attention to detail. Even in the winter, building can go on without sacrificing the quality of the structure if the right supplies and techniques are used. This method enables year-round building and can support projects in adhering to schedules in spite of seasonal difficulties.
