Macro Fibres

Wiking® Macro Fibres are monofilament polypropylene fibres, especially developed to increase the ductility and tensile strength of concrete. The fibres effectively protect the concrete against stresses and external impacts – serving as a superior alternative to steel mesh.

Products include:

Wiking® 4012

Short macro fibres for increasing tensile strength of concrete, especially suitable for high-strength concrete with silica fume.

Wiking® 4050

Long macro fibres for increasing tensile strength and joint spacing, especially suitable for shotcrete and concrete elements.

Wiking® 4050SP

3rd generation macro fibres with an increased specific gravity of above 1.0, which ensures that the fibres do not appear on the concrete surface.

Advantages

Increased tensile strength

Increased flexural strength

Increased impact resistance

Increased joint spacing in floor elements

Applications

Indoor floors
Outdoor ground decks
Agricultural waste tanks
Concrete products requiring high strength
Shotcrete (spraying concrete)

Product description

Wiking® Macro Fibres are made of 100% virgin polypropylene, which has been extruded, oriented, shrunk and subsequently cut in lengths as required. The macro fibres provide a high level of tensile strength and may serve as a cost-effective alternative to steel mesh and bars.

Increased tensile strength

When the Wiking® Macro Fibres are added to the concrete mix, the fibres will form a three-dimensional matrix in the mix and cause for the tensile strength to increase earlier in the drying/hardening phase. As a result, the formation and growth of cracks is prevented, leading to a more durable and strong concrete structure.

Specific gravity of above 1.0

Contrasting to steel fibres, our 3rd generation macro fibres named Wiking® 4050SP do not appear on the surface of concrete. This is because, Wiking® 4050SP fibres have an increased specific gravity of above 1.0, which prohibits them from floating to the surface of concrete. As a result, the concrete product will have a more aesthetic finish and the durability of the structure will increase.

Flexible production that meets your need

We have a flexible production line which easily meets individual customer requirements. Our Wiking® Macro Fibres can be cut into specific lengths or delivered in tow. We also offer special coating for enhanced bonding and an on-site fibre cutting machine for improved efficiency on the building site.
