Durable and highly effective
We collaborated with Empa to develop our highly effective bicomponent macrofibre Concrix as an alternative to steel fibres.
Extensive tests prove its excellent working capacity according to the EFNARC guideline: over 1,000 J with only 4.5 kg of Concrix/m³ at 25 mm of deformation (depending on the concrete mix); the prevention of creep in the bond (demonstrated in a long-term test > 3,000 days); resistance to aggressive liquids (de-icing salt, sulphate).
Other advantages of Concrix are its low rebound and consequently lower fibre and concrete consumption, along with virtually no wear on hoses and nozzles.

The economical and ecological alternative to steel fibresServices
Many advantages in terms of durability, sustainability as well as resource conservation.
The end product – a powerhouse
Various tests conducted by independent test institutes according to the EFNARC guideline prove the excellent working capacity of Concrix. More than 1,000 J with only 4.5 kg/m³ of Concrix at 25 mm of deformation is possible.
The long-term test (creep test) conducted by an independent test institute impressively proves that this fibre structure prevents creep in the bond. The test with Concrix ES, lasting up to 3,000 days in some cases, is unique worldwide.
Concrix fibres are resistant to aggressive liquids (de-icing salt, sulphate). While steel already shows a significant decline in its mechanical properties after only one year, the load-bearing capacity of Concrix does not decrease.
The even distribution of approx. 500,000 fibres per m³ of concrete contributes to these excellent values (at a dosage of only 4.5 kg/m³).
