Reinforced concrete: frame, concreting, recommendations for

Building

Concrete is a fairly durable material, but for some types of buildings need additional flexibility or appropriate reinforcement. This is especially true for dimensional structures, since this large material is easily broken, although it remains quite solid. Therefore, metal or other inclusions are added to the solution and as a result reinforced concrete is obtained.

Manufacturing

First we need to say that there are a lot of options for creating such materials. Among them there are reinforced polystyrene concrete lintels and even constructions based on fiberglass or carbon graphite fabric. However, the most popular products with metal.

Frame

In order for concrete to receive a certain strength, it is created on the basis of a framework made of metal rods.

In this case, concrete reinforced with fiberglass also uses this principle, but the process of its creation has certain differences.

It is worth noting that the reinforcement thickness is not chosen randomly, but due to accurate calculations.. The same applies to the distance between all elements of the structure.

It is believed that when creating foundations or floor slabs, it is best to tie all metal elements in concrete with steel wire rather than welding, since this gives the product a certain mobility and flexibility.

Such an arrangement and choice is related to the fact that the manufacturing instructions assume that the final product will receive a certain amplitude of oscillation that it can tolerate without damage.. There are even structures in which metal cables are installed in order to provide increased tensile strength.
It is important to mention that the reinforcement is made only from structural steel, which cannot be rolled or replaced with more durable. The fact is that otherwise the product may collapse from the inside during operation, and borax on reinforced concrete will fail, bumping into metal.

Tip! When self-fabricating such systems, they usually use a distance of 20 cm between the elements, and the bundle is produced with the help of steel wire.

Each similar product needs preliminary calculations and even small sketches or drawings.

Concreting

If reinforced cellular concrete is created, then it should contain sections that will form cavities.

For casting, a special composition of the solution is used, to which plasticizers and other additives are added, endowing the final product with certain qualities. At the same time, the price of such substances affects the final cost of production.
After the solution is poured into a mold, a special vibrator is immersed in it. This is necessary in order to remove all air bubbles from the composition, which, after solidification, create shells that weaken the structure. Such defects can be seen when cutting reinforced concrete with diamond circles.

In the finished formwork should be taken into account not only the ratio of all sizes, but also the presence of additional elements that will be needed in the subsequent stages of construction

In order to speed up the process of solidification, professionals recommend using rags, which are soaked in ammonia solution and placed on the product under the film.

Tip! Experts say that the final product is necessary not only to dry completely, but also to stand for a week. So concrete will gain strength and become ready for use.

Recommendations for manufacturing technology

If the design needs technological holes, then they should be foreseen at the filling stage.

Otherwise, diamond drilling of holes in the concrete may be required.

The secret to the rapid solidification of the material lies in the use of a film and rags with an ammonia solution, which draw all the moisture towards themselves even at the molecular level.

Professional craftsmen recommend making elements of buildings directly at the place of their installation. So they get the desired shape and an excellent bundle with other surfaces.
If the manufacture is done by hand, then you need to make sure that when pouring the liquid does not flow out of the formwork. To do this, it is better to put a film on its bottom. Some experts prefer to use roofing material for this to immediately create a waterproofing, which will remain after casting.

Professional masters prefer to order a ready-made solution, in which the manufacturer has already added all the necessary additives and withstood the required temperature, which is especially important when working in the winter season.

Conclusion

After thoroughly studying the video in this article, you can get more detailed information about similar materials and methods of their manufacture. Also based on the article that is provided above, it is necessary to conclude that the creation of such products is a fairly simple process that requires strict adherence to instructions and free space (also find out what the depth vibrator is for concrete).
