Today, residents of large cities are increasingly moving to cottage villages, where you can relax from everyday bustle and noise. Many choose houses made of reinforced concrete panels. And this is not surprising: the construction of cottages allows you to get the object for a short period of time, rather than dragging out work for months and even years.
Zhbi cottage - a reliable house in a short time
Individual buildings made from jib have long become a model of ergonomic construction, allowing to reduce operating costs with a high level of comfort and safety.
Cottages made of reinforced concrete panels are also known for their durability and long life. If you believe the well-known saying "my house is my fortress", then the cottage from the zhbi completely corresponds to it. Such a construction will reliably protect the owner from the negative influence of the environment: cold, fire, strong gusts of wind and heavy rains. Due to the high rigidity of the frame, it does not deform and retains its attractive appearance.
That is why the houses from the jabi are deservedly popular all over the world. According to the National Association of Housing Builders (NAHB), in 2014 in the US, the volume of construction of cottages from the zhbi was almost 29% of all single-family houses. Simply put, every third of the new cottages in the US today is made of concrete.
The advantages of such buildings are obvious - more efficient installation in comparison with houses made of foam and aerated concrete, lack of "wet" works inherent in monolithic construction. The cottage of reinforced concrete panels has high insulation and design characteristics. This technology allows you to implement any architectural ideas: from the estate, the so-called "noble" style to modern.
However, many can not guess that this or that house is made of a zhby, as the walls are often hidden under a classical facade of plaster, brick or siding panels. However, one should not be surprised at the stories of his acquaintances about the amazing cottage that "grew up" in a nearby plot in just a week. This means that someone has already decided to realize his dream!
Construction of cottages in Moscow
The construction of cottages from reinforced concrete panels is a service that is in demand also in the Moscow region. The company LLC "Stroykomfort +" carries out this type of work on the following popular technologies:
- construction from prefabricated reinforced concrete (from ready-made concrete structures);
- construction of monolithic reinforced concrete (pouring into the formwork of liquid concrete).
The first way is actual for creation of standard cottages on the basis of ready projects, and the second - for erection of original houses of any complexity. The cost of reinforced concrete cottages is traditionally low and available for a wide range of customers.

With all the modern variety of building materials, concrete firmly holds leadership in the construction market. This fact is due to the reliability of the material and the durability of the constructed building. Special attention should be paid to structures based on finished blocks. During the construction, both new and used reinforced concrete slabs can be used.
Types and applications
It is a ready-to-use panel manufactured in the factory. There are several basic types that are presented in the table and are distributed according to their appearance and purpose:
| Road | This type is used for laying motorways and roads for various purposes. |
| Ribbed | In a different way, concrete slabs of coatings. As it becomes clear from the name itself, they are used as a coating for designs for various purposes. GOST for reinforced concrete ribbed slabs provides for their production solely from high-quality heavy concrete. |
| Cornice | These are used in the construction of buildings, where the project provides the presence of balconies and loggias. |
| Hollow | As they are called, voids. This is the most common and widely used type. They are used both in low-rise and high-rise buildings. |
Important! In many cases, the purchase price, delivery and installation of finished slabs is lower than the cost of a monolithic slab.
Construction of a house
First of all, it is worth saying that concrete, it's pretty dense and heavy material. Therefore, the question of how much the reinforced concrete slab weighs is more than relevant. We give a concrete example, taking for consideration a block with dimensions 2 * 3 * 0.2 (meters). Such a block, depending on the presence of reinforcement in it, will weigh from 2 to 3 tons.
Benefits
The use of prefabricated blocks during the erection of buildings has several advantages over other types of construction:
- Speed of erection of a building. Thanks to the use of ready-made structures, the construction is reduced to the implementation of a set of standard actions that the instruction establishes, and the house can be built in six months.
- Since the production process is carried out in the factory, it is not influenced by external factors, and the risk of marriage at the production is minimized.
- Ready plates are brought to the building site as the object is ready. This allows you not to accumulate building material in the construction site.
- Finished panels, in themselves, are large objects, so it is quite easy to control them.
- Dimensions of reinforced concrete slabs allow to erect not only standard designs, but also to produce small precast blocks, which helps to implement non-standard architectural solutions.
- The use of prefabricated units allows the installation of window and door frames of standard dimensions. This is important, as, for example, in houses made of bricks, the size of the door and window openings always varies, and this gives inconvenience.
Important! The walls of buildings built from prefabricated blocks are smooth, so they do not require putty. Accordingly, you can immediately start painting the walls. This work can be done even with their own hands.
- If the production was observed GOST on reinforced concrete slabs, then such structures are durable. Since the block combines, this allows the design to resist not only compression loads, but also tensile stress.
- This building material is chemically neutral, that is, the release of harmful substances into the environment is excluded. It should be noted the refractoriness of the material, which increases the fire safety of the entire structure.
Minuses
But except for pluses, buildings, assembled their finished blocks, there are disadvantages, which should be mentioned:
- Very high coefficient of thermal conductivity of reinforced concrete slab. Depending on the density, this index varies from 1.28 to 1.51. With the increase in the density of the material, this indicator grows.
Such designs are practically unable to retain heat. Thermal insulation qualities can be improved by using hollow slabs. The air contained in voids helps to minimize the thermal conductivity of the reinforced concrete slab.
- Sound insulation in such homes also leaves much to be desired. Concrete very well conducts sound waves. The solution, as in the previous paragraph, can be the use of hollow blocks.
They have a greater noise-isolating effect than others. This is due to the fact that the density of reinforced concrete slab of this type is much lower.
- The design features assume the presence of interpanel and intertitic joints. These seams should be sealed with the greatest possible care. If this is not done, then the room gets cold and damp, which leads to the formation and growth of mold fungus on the walls.
- The weight of the reinforced concrete slab is quite large, which complicates the procedure, manipulations with it.
Important! Despite all these drawbacks, prefabricated slabs are an excellent building solution when reliability and construction time are important.
Conclusion
Building a house of reinforced concrete hollow or other slabs is not necessarily the best option, however, this possibility is not excluded in construction. As a rule, this kind of building material is used more for multi-storey construction.
In low-rise construction, concrete slabs are used not so much for the erection of residential buildings, as for garages or cellars. How to properly find an application for this material will show the video in this article, which will be an excellent recommendation on many issues.

Despite the emergence of modern high-tech building materials, the construction of reinforced concrete slabs continues to be the most common development option. Prefabricated houses made of reinforced concrete are built in a very short time, allowing you to quickly put into operation as individual housing, as well as high-rise buildings, shops, other infrastructure.
House of reinforced concrete slabs with your own hands
All building structures are made in production conditions, which excludes the influence of atmospheric influences and the human factor, as it happens when building monolithic concrete or brick buildings.
Construction works do not stop in the winter, again in comparison with monolithic and brick construction. Common prefabricated reinforced concrete house can be built in less than six months. On the construction site the structures are brought in ready-made form as they are mounted. Since the structures are large enough, it is easier to monitor them. In addition, it is not necessary to concentrate all the building material at once on the construction site, which facilitates the entrances and reduces the subsequent costs for the improvement of the territory.
Modern methods of producing reinforced concrete slabs allow producing small precast reinforced concrete elements along with large typical panels, which makes it possible to build houses with original architectural solutions. At the same time, the remaining dimensions of RC elements allow the installation of window and door units of standard dimensions. For example, it is very difficult for brick buildings, in which the sizes of window and door openings always vary. The construction of concrete slabs makes it possible to dispense with skeletons and make the walls smooth. They can be used for painting works and without continuous finishing with putty.
Buildings of this type have a long life, are very reliable and safe. The material is fireproof and fireproof. The reinforced concrete slabs themselves are very resistant to loads, including dynamic ones. A successful combination of prestressed reinforcement and concrete allows the construction to be protected from stress and tensile and compressive forces.
ZHBI - the material is chemically inert, excluding the flow of any chemical reactions that can disrupt the performance characteristics of the structure.
One of the main disadvantages is the insufficient sound insulation of the premises, due to the good transmission of concrete by sound waves, which provokes the appearance of an echo.
always has interpanel or intertitic seams, for which a particularly careful sealing is necessary. If even a small gap is left, it is possible to penetrate the room with moisture, which leads to dampening of the walls and the possible appearance of mold fungi. The seams between the slabs are cold bridges, and in addition, further reduce the sound insulation of the rooms.
Since reinforced reinforced concrete does not accumulate enough heat, the RC structural walls easily freeze under severe frosts and are heated in the sun on hot days.
The above disadvantages can be largely compensated by using lightweight reinforced concrete slabs having a large number of internal voids. Particularly justified is the use of such plates in low-rise construction. The air layers contained in the voids extinguish the sound waves, increasing the sound-insulating properties of the plates, and also increase their thermal insulation properties. However, it should be borne in mind that lightweight hollow slabs impose restrictions on the laying of new utilities: strobing has to be done with great care, since there are many voids in the ceilings.
To the disadvantages of the technology of building a house from reinforced concrete slabs can be attributed and the complexity of controlling the wear of each individual building element.
