Here at "All about Concrete," we explore the different varieties of concrete and their distinct characteristics. Today, we look at Sibit aerated concrete, a substance that is renowned for being strong but lightweight.
One characteristic that sets Sibit aerated concrete apart is the large amount of evenly distributed air bubbles in the material. When a foaming agent is added to the concrete mix during the manufacturing process, air bubbles are created. Sibit aerated concrete is therefore significantly lighter than conventional concrete, which facilitates handling during construction.
Sibit aerated concrete is remarkably strong despite being lightweight. This is accomplished by carefully weighing the components and curing the material, which strengthens its structural integrity. It is frequently employed in situations where insulation and strength are essential.
Sibit aerated concrete’s superior thermal insulation qualities are one of its main benefits. Tiny air pockets are created by the material’s air bubbles, greatly reducing the amount of heat transfer through the walls or other structures composed of this concrete. Sibit aerated concrete’s ability to control interior temperature and lower energy use makes it a great option for structures located in a variety of climates.
Sibit aerated concrete also has strong acoustic insulation qualities. The material’s air voids aid in sound absorption, minimizing the transfer of noise from outside sources or between rooms. An atmosphere where people live or work that is calmer and more comfortable is enhanced by this acoustic performance.
Sibit aerated concrete is well-known for its fire-resistant qualities in addition to its insulating qualities. Because of its mineral makeup and air voids, the material has a high fire resistance, giving residents plenty of time to flee in the event of a fire.
All things considered, Sibit aerated concrete offers fire resistance, strong structural integrity, good thermal and acoustic insulation, and lightweight design. Because of these qualities, it can be used to a wide range of construction projects, from residential to commercial, where sustainability, safety, and efficiency are critical considerations.

Components
In order to create superior sibit aerated concrete blocks, you must first mix a porous structure consisting of pre-crushed materials such as cement, lime, sand, water, and aluminum powder. Once the solution is ready, it is formed into large monoliths that are then cut into the appropriate size blocks after hardening.
After that, an autoclave oven will be used to treat the aerated concrete under high pressure. This procedure is required to give the final product the highest strength and other advantageous qualities.
Application areas
Concrete with aeration is a special kind of material. Practically every construction industry uses it. Typically, these kinds of blocks are employed in:
- construction of private estates of various sizes;
- construction of utility buildings;
- construction of massive industrial structures;
- laying of interior walls;
- insulation of facades if the building itself is made of other building materials;
- formation of door and window openings.
Technical characteristics and advantages
Builders adore aerated concrete sibit because of its many benefits:
- Wall weight . One square meter of wall made of Sibit blocks is 5 times lighter than the same area of brickwork, due to which when building cottages, savings on foundations increase by 10-15%.
- Thickness of walls. A gas concrete wall is half as thick as a brick wall. International technical standards have established that the masonry of a gas concrete wall should be at least 60 centimeters thick.
- Vapor permeability. Vapor permeability of the material in question is 0.17 g/m, which is 6 times higher than the same property of brick. This process indicates accelerated removal of moisture from the material, thereby helping to maintain the required microclimate, fresh air inside the building.
- Thermal conductivity. Thanks to this property, which is 4 times less than the thermal conductivity of brick, heat is saved by 20% in buildings made of sibit aerated concrete. This is especially important during the heating season.
- Frost resistance. GOST standards have established the minimum number of winter cycles with subzero temperatures that aerated concrete structures must withstand. However, Sibit brand material can easily withstand about 200 frost cycles. This solution owes its resistance to frost to its bubbly structure. Numerous air pores absorb moisture in the cold season, thus saving aerated concrete monoliths from disintegration.
- Fire safety. Aerated concrete of this brand is produced exclusively from natural minerals. Therefore, this building material is fireproof. Thanks to these qualities, houses made of aerated concrete can withstand a fire load on one side lasting from 3 to 7 hours. This is how metal structures that serve as reinforcement for aerated concrete structures are protected from fire.
- Floor slabs. The strength of aerated concrete floor of the Sibit brand is 800 kg. If you cover the roof with such slabs, this will provide the most acceptable temperature in the attic, allowing you to create living conditions there. In addition, when building a one-level house, covering the roof with aerated concrete slabs will reduce the amount of wood and metal used. Also, due to the installation of connected roll-free roofs, there is no need to use staples. All this makes the construction process somewhat cheaper.
- Durability. Aerated concrete owes this property to a special technology for producing the material – autoclave processing.
Furthermore, this material is excellent for making frame structures. It is not advised to heave massive, heavy objects against walls of this kind. It is preferable to use specialized fastening to attach hanging cabinets or other comparable objects.
Labor and financial costs
Compared to, say, brick, working with this brand’s aerated concrete is far simpler and easier. The blocks’ light weight is the cause of this. This is a material that is easily processed with common building tools that are accessible to all builders.
One aerated concrete block can be installed with 15 to 20 bricks laid, greatly reducing labor intensity and construction time frames. After all, you can construct 15 m3 of aerated concrete in the same amount of time it takes to construct 7 cubic meters of brick.
You will also save a lot of money by selecting the right building material sibit when building a house. After all, only five builders can complete the construction of a building with an approximate area of 250 m2 in just one month, so no additional auxiliary materials, technological devices, or labor are required in this instance.
This material can be transported without any problems and without requiring large financial outlays.
The special qualities and advantages of Sibit aerated concrete, a lightweight and environmentally friendly building material that is becoming more and more popular in the construction industry, are examined in this article on "Characteristics of Sibit Aerated Concrete." Sibit aerated concrete is unique in that it has superior thermal insulation qualities that lower building energy expenses.

Production technology
The use of quicklime in the binding process of other ingredients sets apart the production technologies for this type of aerated concrete. In addition, the solution is combined with the necessary quantity of cement sand. Every operation involving crushed quicklime is completed automatically in transport lines and tightly sealed containers.
For lime and air to interact as little as possible, this technique is required. If not, the slaking period might start earlier than planned, which might violate the solution’s swelling requirement. The production of high-quality goods is made possible by these actions. Aerated concrete becomes porous when aluminum powder is added to the mixture. Aluminum powder reacts with calcium oxide hydrate for approximately a minute before starting to change into a porous material.
The mixture is pre-ground using a wet method for approximately 8 hours before sand is added. Automated weighing dosing devices that can independently modify the component proportions are used to feed the ingredients.
Additionally automated is the feeding of formed, cut blocks into the autoclave furnace, where the material is subjected to the last strength test. The aerated concrete monoliths are steamed inside the autoclaves at a pressure of 12 kg per square centimeter of the finished product. This takes ten hours to complete. After that, the completed item is automatically packed with tape, placed on pallets, and moved to storage.
