Strong as Stone with Basalt Fibres

Concrete Channel Material - New Era Begins

Mineral Building Material for Hauraton Drainage Channels

Even the ancient Romans knew the benefits of concrete. Today, it is impossible to imagine modern structural and civil engineering without the artificial stone. Hauraton now makes the building material even more efficient for modern drainage technology - through the new formulation with natural basalt.

Concrete can absorb high compressive stresses but only low tensile stresses. Over the centuries, it has therefore been optimised further and further. In so-called reinforced concrete, steel inserts (reinforcement) in the tensile zones take over the stress absorption. The addition of mineral or textile fibres, on the other hand, increases, for example, green strength, edge strength or crack resistance. For Hauraton, the latter is of particular importance: the higher the crack resistance, the more robust and durable the product. This is particularly important for components that are exposed to considerable dynamic stresses. This is the case with drainage channels which are sometimes driven over by vehicles at high speeds or regularly subjected to heavy loads. This is why Hauraton, as one of the market leaders providing impetus, is continuously active in research and development for the benefit of building material optimisation.

Progress with Basalt Fibres: Natural, Emission-Free Even More Sustainable
Now Hauraton has ushered in a new era in concrete production. By adding basalt fibres, not only a durable building material is created, but also one that is 100 percent natural. The basis, basalt rock, is available all over the world. It is available in large quantities and is formed anew every day on our earth. If the basalt rock is liquefied, various types of fibres can be made from it which have impressive properties. In combination with the well-known material concrete, both the serviceability and the service life of the products are increased. For the Faserfix drainage systems, which are made of fibre-reinforced concrete, the use of basalt fibres now brings many advantages.

Natural Product with Better Environmental Balance
Basalt fibres are revolutionising concrete as a material because they offer numerous benefits. The decisive plus point is that the fibres of the volcanic effusive rock are a purely natural product, and no chemical changes are made to the basalt in their production. While the sustainability factor is increased, the production costs are reduced at the same time. In addition, the amount of cement can be significantly reduced with a comparable concrete quality which has a positive effect on the CO2 balance. All the desired properties of the end product can be achieved by using fewer fibres and thus lead to more economical use.

Mineral Mixture Easy to Recycle
Another advantage, in addition to the resource-saving and efficient production, is the simple recyclability at the end of the product's life cycle. Since the end product is a purely mineral mixture, there is no need for material separation during disposal. This protects the environment to a high degree. In addition, according to current knowledge, basalt fibres do not form WHO-critical fibre dusts during processing or recycling which can cause lasting damage to the lungs.

Convincing Strong Properties
Basalt fibres have outstanding properties: they withstand temperatures of up to 800°C. They are high-strength, flexible, non-toxic, non-carcinogenic, alkali-resistant according to EN 14649 and ASTM C1666/C1666M and UV-stable. This makes applications possible for which other fibres cannot be used or are too cost-intensive.

If one compares the effects of adding basalt with the previously used fibres, it becomes clear: the basalt fibres make the precast concrete elements even more dimensionally stable and thus guarantee the very high quality. The durability of the channel material is improved as the weathering of the surfaces is greatly delayed compared to concretes previously used. Drainage systems made of basalt-reinforced concrete will thus remain in use much longer than is already the case today. At the same time, the impact strength increases significantly. This goes hand in hand with reduced cracking. Both the number and the width of cracks are reduced.

Mineral Power Particles: Basalt Fibres are Versatile and Climate-Friendly
Both glass fibre and basalt fibre are mineral fibres. However, unlike glass fibre, basalt fibre has a higher melting temperature, better resistance to water, acids and alkalis, and more positive tensile and bending properties. All this makes basalt fibres attractive in drainage technology, but also in numerous other applications in construction, energy and environmental technology and much more.

In view of the stricter climate targets, the energy consumption during production also clearly speaks in favour of basalt fibres: Compared to other fibre materials, they have the lowest CO2 footprint. Conclusion: Anyone who wants to manufacture resistant and durable concrete products in an economical and environmentally friendly way will not be able to avoid basalt fibres in the future.
