Metallic fibers are scrappy strips of small dimensions, of a type of steel with special properties. The disperse reinforcement of the concrete with metallic fibers improves considerably the mechanical properties thereof.

The most frequent use of metallic fibers in the construction industry is the constructive reinforcement of the regular reinforced concrete. This type of reinforcement represent a segment under continuous development in the cement industry, as engineers, architects, and contractors use more and more often the metallic fibers to ensure the success of their projects with concrete constructions.

In large constructions like buildings with several floors, highways, bridges, plane tracks, floors, metallic fibers are mainly used to:

  • Increase resistance to bending or shearing
  • Increase resistance to high temperatures and decrease deformations through contractions, pursuant to the drying of the concrete

USE




The latest research in the field has proven that soon metallic fiber would be able to fully replace the steel-concrete reinforcement. To this respect, there are successes in consolidating inner walls, but also in structural pillars (coating), the production of precast elements, or the performance of floors with varied dynamic stress.

By distributing randomly the metallic fibers manufactured at the highest standards, with the Fibro Metals technology, there is even dispersion of the stress on the entire surface of the cement mould. Micro-cracks, which usually widen proportionally with the increase of the stress, are stopped by the mesh formed by the fibers inserted in the concrete, thus stopping the deep micro-cracking and, subsequently, the deterioration of the build area.

WHY METALLIC FIBERS?

  • Because the use of metallic fibers for the disperse reinforcement of concrete increases considerably the resistance thereof to dynamic shocks
  • Because they offer both constructive, and economic advantages, as compared to the reinforcement with reinforcing iron
  • Because it improves considerably the mechanical properties of the concrete
  • Because it increases the resistance of concrete to temperature variations
  • Because the concrete reinforced with metallic fibers has a highly resistant to corrosion
  • Because due to tridimensional reinforcement with metallic fiber, the reinforced area bears a higher stress
  • Because for a significant number of applications, it is not necessary to use a metallic mesh reinforcement anymore
  • Because the process of inserting fibers in the cement can take place directly in the cistern, without a pump
  • Because their use automatically leads to a decrease in reinforcement expenses and execution time
  • Because the field of use of the concrete reinforced with metallic fibers is very wide: concrete pipes, precast elements, airport tracks, foundations, flooring, lost shuttering, consolidation works for tunnels (cement concrete).
