Textile-reinforced concrete using corrosion-resistant reinforcements like alkali-resistant (AR) glass fibres or carbon is economically and functionally superior to classical steel-reinforced concrete. Thanks to their excellent material properties, most notably freedom from corrosion but also lightness and flexibility, textile reinforcements have made their entrance into the modern concrete construction market and will greatly transform and extend design possibilities for architects, engineers and manufacturers of prefabricated components. This technological transformation will take reinforced concrete construction in entirely new directions, and is already making visible and lasting changes to the industry today.
The advent of textile-reinforced concrete has led to corrosion damage and the high costs associated with the rehabilitation and maintenance of steel-reinforced concrete being a part of the past. Concrete elements can be made thinner, more delicate and more efficient owing to tensile strengths that can easily exceed 3,000 N/mm², thus opening up a range of new applications in construction, exterior design and furniture. Not least, textile-reinforced concrete construction is cheaper and more attractive
Advantages of textile reinforcement and building with textile-reinforced concrete:
- No corrosion damage
- Durable concrete elements
- Strength properties five to six times that of conventional steel-reinforced concrete
- Minimal concrete covers allowing for thinner, slender and lighter designs
- More building space is available to rent since façade designs are 80% thinner
- Low transport costs for prefabricated elements
- Easier installation of reinforced structures
- Especially suited for structures exposed to high chloride stresses, such as bridges, parking garages and maritime structures.
Colleges and research associations have been working on the development of alternative reinforcement materials since the mid-1990s, and the enormous future potential for textile-reinforced concrete was recognized even earlier. Together with partners in the industry, solidian pioneered the way into the market while the process of turning basic research into concrete product solutions began more and more to take shape. solidian, with its headquarters in Albstadt, one of the leading centres of textile technology and research in Germany, was active in making early contributions to this development and was able to innovate marketable products from its first promising pilot projects, which are being successfully used in a variety of areas within the construction industry today.
Since there are no existing standards for textile-reinforced concrete, solidian has been driving the technology forward with its own general technical approvals in Germany, for structures like sandwich walls, prefabricated garages and foot and bicycle path bridges (in process at this time). In addition, a general technical approval for a waterproof reinforced concrete element with a crack width limitation achieved with carbon reinforcement has been in existence since August of 2015. solidian’s technological expertise combines the ideal fibre materials, impregnation and shaping in order to realise all kinds of customer or project-specific requirements for form and stability.
