Textile concrete - what about the costs?

Textile concrete is one of the most innovative building materials that has been developed in recent years. By replacing the reinforcement with innovative fiber fabric very thin, yet high-strength components are possible. Of course, such modern technology also has its price: as it currently looks with sources and costs, read here.

Innovative technology

Unlike fiber-reinforced concrete, the textile fibers form a fabric. This fabric can be customized for each prefabricated component. The fibers are then reinforced in the direction of the forces acting and thus increase the stability of the component. This also means that above all prefabricated components made of textile concrete are used.

The fiber fabric is surrounded by a special fine concrete, tailored to the respective fabric type, with a density of only 600 kg / m³. This makes extremely lightweight, but also extremely stable components possible.

Fibers can be made of different materials:

  • special glass (alkali-resistant glass)
  • Carbon (especially expensive) and
  • basalt

Source of supply of textile concrete

Current application areas include almost exclusively the bridge construction, on the edge of individual shells for roof structures and facade parts are already made of textile concrete. It will certainly not be possible to produce it as workable and freely usable concrete in the foreseeable future. Textile concrete is mainly used in prefabricated parts.

So far, there are hardly any products on the market in which textile concrete is used. This should be changed by massive subsidies and special programs. The textile reinforcement should be able to replace a large amount of conventional steel reinforcements by as early as 2030.

Until then, however, these products remain rare on the market, and components made from textile concrete are still extremely expensive. In most cases, a custom-made component is hardly an option. In the case of load-bearing parts, the necessary dimensioning of the component also poses a problem, since important empirical values ​​are still missing in order to be able to correctly dimension a component.

Tips & Tricks

Steel fiber reinforced concrete is also a very innovative new development in the concrete sector, which can already be used profitably today. In some cases cost savings of up to 25% are possible compared to conventional reinforced concrete.
