Basalt Fibres
Stronger than steel – light as a feather

Wiking® Super B is a new, ground-breaking product on the market of concrete reinforcement. The fibres are made of basalt, a volcanic rock, which is four times stronger and four times lighter than steel. Hence, basalt fibres are an ideal and cost-effective alternative to reinforcing steel.

Products include:

Wiking® Super B – Roving

Micro basalt fibres for preventing concrete cracking and increasing tensile strength, also suitable for mortar and other cement-based mixes.

Wiking® Super B – GeoGrid 400

Rebar of basalt fibres, suitable for concrete and asphalt reinforcement (e.g. roads, highways and bridges) as well as concrete structure renovation.

Wiking® Super B – Rebar

Macro basalt fibres for increasing tensile strength and ductility of concrete.

Wiking® Super B – Chopped

Alternative to steel bars, offering four times the tensile strength of steel, especially suitable for construction of bridges.

Product description

Wiking® Super B Fibres are made of 100% crushed basalt, a type of volcanic rock, which is found all around the world. To produce the fibres, basalt is melted at 1600 C and then spun and extruded into very fine fibres.

Basalt is naturally resistant to external influences (such as alkalis, acids, extreme temperatures, water and rust), hence, no special coating of the fibres is needed.

Stronger than steel – light as a feather

Basalt is much stronger than steel and also 75% lighter than steel (in terms of density). This means that a smaller volume of basalt fibres is needed in comparison to using steel fibres.

Due to the exceptional strength of basalt, the fibres may allow for thinner and lighter concrete decks and panels. Depending on the construction, basalt fibres may even replace the need for steel mesh and steel bars. Hence, using Wiking® Super B may bring large cost savings to a construction project.

Improved concrete surface quality with basalt fibres

In contrast to steel fibres, basalt fibres do not appear at the surface of concrete, but will stay within the concrete mix. This leads to a more durable and aesthetically pleasing concrete surface.

Extending the duration of concrete and asphalt with basalt fibres

Importantly, basalt fibres can prevent the formation of plastic shrinkage cracks, as the fibres will cause the tensile strength to develop early in the drying/hardening phase. Also, basalt fibres will cause an increase of elasticity, making concrete and asphalt more resistant to impacts and bumps, for example those caused by heavy traffic.

Environmentally friendly and easy to dispose of

Basalt fibres are completely natural as they are made of crushed magmatic rock, which is found all around the Earth. This means that they are easy to dispose of. As an example, when a building is demolished, steel fibres and steel mesh need to be separated from concrete for disposal, whereas basalt can be disposed together with concrete.

Flexible solutions to your needs

Wiking® Super B fibres are available in various sizes to suit your concrete application. Please contact us for more information.
