r wave eco

Family: Metal fibers for general purpose

Application: Structural concrete with fibres

r wave eco is a recovery fibre, used in screeds. Its shape and length of development prevents the opening of cracks in the first hours of setting and provides residual strength. Unlike traditional structural reinforcing steel, it distributes the stresses throughout the concrete mass with much less execution time. Steel prevents cupping or creep deformation and provides impact resistance.

Frequently asked questions

What is r-wave-eco fiber?

r-wave-eco is a high-performance structural steel macrofiber designed for concrete reinforcement. Its two key features are its wavy geometry ("wave") for superior mechanical anchorage and its focus on sustainability, positioning it as a steel reinforcement solution with a lower environmental impact.

What exactly does "eco" in its name mean?

The "eco" suffix highlights its profile as the most sustainable steel reinforcement. This is achieved through an optimized production process or the use of raw materials with a recycled component, resulting in:

Lower Carbon Footprint: A significant reduction in CO₂ emissions compared to the production of conventional steel fibers.
Promotion of the Circular Economy: It contributes to a more responsible and lower-impact construction model.

What structural capacity does r-wave-eco offer?

As a steel macrofiber, it offers excellent structural capacity. It is designed to provide high residual strengths to concrete (ductility), allowing it to replace traditional wire mesh and/or other steel fibers in demanding applications such as industrial floors, precast elements, and shotcrete.

What is the advantage of its wavy shape ("wave") compared to hooked fibers?

The continuous wavy geometry along the fiber is designed to create a multi-directional mechanical anchorage within the concrete matrix. Unlike anchorages concentrated at the ends (hooks), the "wave" shape distributes anchorage stresses along its entire length. This provides outstanding pull-out resistance and effective load transfer across cracks.

For what projects is r-wave-eco ideal?

It is the perfect solution for any project requiring structural steel reinforcement but where sustainability is a decisive factor, such as in:

Buildings with sustainable certifications (LEED, BREEAM).
Industrial slabs and pavements where reducing the project's carbon footprint is a goal.
Civil engineering and precast projects with strict environmental specifications.

How does its performance compare to other RIMSA steel fibers?

r-wave-eco is engineered to offer structural performance comparable to other high-performance steel macrofibers. Its main differentiating factor is not just mechanical performance, but the combination of that structural capacity with a superior sustainability profile.

How is it added and mixed into concrete?

It is added in the same way as other steel macrofibers: directly at the batching plant or into the mixer truck on-site. A short mixing time at high speed is required to ensure a fast and homogeneous three-dimensional dispersion.

Is it a cost-competitive alternative?

Yes. r-wave-eco is designed to be a competitive, high-performance steel reinforcement solution, offering the added value of sustainability, which can lead to savings and benefits in the overall project assessment (certifications, brand image, etc.).
