What is twin blocks?
A type of cellular aerated concrete known as twin blocks is created by autoclaving and is regarded as a cutting-edge, high-tech building material. Originally owned by Teplit, a Russian company, other businesses are now manufacturing the technology’s building blocks under the TwinBlock brand.
Twinbloki means "twin blocks" when translated from English, and this is what sets them apart. Because every product is identical, geometrically precise, and even, masonry is produced rapidly, greatly easing the master’s work.
Unlike other varieties of aerated concrete, twin blocks have a composition. They are constructed using the following elements:
- Portland cement;
- dry aluminum powder or suspension on its base;
- Izta-Pushonka (calcium hydroxide);
- coal ash;
- water.
Because it gains numerous tiny air-filled pores during production, the final building material is light but durable. Twin blocks are vapor permeable, safe, and resistant to fire. They are frequently used to construct exterior walls because of their small mass, which places little strain on the foundation.
Crucial! Twin blocks are perfect for creating low-rise (up to three-story) buildings, industrial facilities, garages, sheds, residential buildings, baths, and saunas. They are also appropriate for building educational, childcare, and medical facilities.
Production technology and varieties
Every element needed to make twin blocks is combined into a single mixture and then diluted in a specific amount with a liquid. Thus, an aluminum and lime chemical reaction takes place, and active gas formation starts. The material foams and turns porous. The aerated concrete mixture cures while the cement hydration reaction continues in parallel.
The composition is thoroughly mixed and poured into special forms even before the point of hardening. Large blocks are first divided into smaller ones using highly precise machinery. Later, elements of crests and grooves are formed in the smaller blocks, and on the sides, hand captures and deepening occurs. Twin blocks’ cutting accuracy is a crucial feature, and any geometrical deviations must not be greater than two to three millimeters.
In the future, goods will be strengthened and made more dependable by being fired in an autoclave furnace at a pressure of 12 MPa and a temperature of roughly +190 degrees. The material is naturally dried until it is ready for sale. Twin blocks shrink at a rate of only 0.56 mm/cube. m after drying, which is regarded as a minimum indicator among analogs.
Different-sized twin blocks are produced by manufacturers. Depending on the dimensions, these are their primary brands:
- TB-100-625*100*250 mm;
- TB-150-625*150*250 mm;
- TB-200-625*200*250 mm;
- TB-240-625*240*250 mm;
- TB-300-625*300*250 mm;
- TB-400-625*400*250 mm.
The remaining products are primarily used for interior partitions, and blocks with a width of 200–400 mm are ideal for building load-bearing walls. Furthermore, the strength, resistance to frost, and vapor permeability of twin blocks vary.
These qualities lead to the following classification of the material:
- D-400. Constructive strength of the blocks – B2, vapor permeability coefficient – 0.25, frost resistance – 50 cycles. The thermal conductivity of the Twin blocks of the brand D-400 is 0.08 W/m*s.
- D-500. Strength – B5, vapor permeability coefficient – 0.2, frost resistance – 100 cycles thermal conductivity is 0.115 W/m*s.
- D-600. Have the same strength as the previous brand (B5), but their vapor permeability is slightly lower (0.18). Thermal conductivity coefficient is 0.131 W/m*s. Frost resistance – 100 cycles.
It is common practice to indicate the letter "P" in the marking if there is one, as some manufacturers do not form a groove system in the tweet blocks.
Properties and characteristics
When it comes to building materials, twin blocks are competitive. Their advantages are undeniable and their operational characteristics are at a high level:
- Moderate weight. Since the structure of the blocks is saturated with pores, the mass is an order of magnitude smaller than that of brick, reinforced concrete. Twin blocks of the smallest size weigh about 8 kg, the largest – 33 kg. Their size is impressive, so the construction process will definitely go faster.
- Good indicators of heat and sound insulation. Due to the special composition and porosity, the blocks are 3-4 times more efficiently held by heat in the rooms, make it possible to maintain a comfortable temperature at any time of the year. In the zones of a temperate climate, they can not even be insulated additionally. Twin blocks also have reliable soundproofing qualities, and from them you can build houses located even near motorways.
- Strength, resistance to the action of negative factors. The material is not inclined to deformations, mechanical damage, is non -combustible, withstands heating up to +400 degrees for 12 hours. The service life of twin blocks is more than 100 years. Their frost resistance is also at the highest level.
- Environmental Safety. Twin blocks do not contain components that could harm human health or environment. In addition, they can be safely called hygienic – mold, fungus do not settle on them, rodents and insects do not live.
- Simplicity of work. Blocks are easily sawn, cut, drilled, due to the presence of special recesses in them, you can put reinforcing rods. Thanks to the correct geometry and the spike-paz connection, the assembly of the house is possible even without the participation of professionals. After the blocking of the blocks of the bridge of the cold, there are no.
Cons of material
One of the drawbacks is that tweet blocks are more expensive than regular aerated concrete (starting at 3000 rubles per cubic meter). The product’s porous structure makes strong anchors and dowels poorly held, which makes it challenging to fasten a heavy boiler or cabinet.
Twin blocks are a novel building material that has several advantages for contemporary architecture. They are made up of two layers, usually separated by an insulating layer that offers superior thermal efficiency. Over time, this design results in significant energy savings by keeping homes cool in the summer and warm in the winter.
Constructing a contemporary warm house using twin blocks is a simple procedure that blends conventional masonry methods with contemporary building supplies. Because the blocks are simple to handle and put together, building is completed more quickly and effectively. Their insulating qualities also mean that less additional insulation is required, which can cut down on building time and costs even more.
Twin blocks’ strength and durability are additional benefits. They offer a strong, sturdy structure that is resistant to different types of weather. They are therefore a great option for creating durable homes that need little upkeep. In addition, twin blocks are frequently constructed from environmentally friendly materials, supporting sustainable building techniques.
All things considered, twin blocks are a workable and efficient way to build warm, energy-efficient homes. They are a desirable alternative for both contemporary builders and homeowners due to their blend of thermal performance, usability, and durability. Twin blocks allow you to design a modern, affordable, and ecologically friendly home that satisfies all of today’s needs.
Aerated concrete blocks, sometimes referred to as twin blocks, are a popular contemporary building material because of their superior insulating qualities, portability, and simplicity of use.
