  • Fiber lengths of 4 to 18 mm, preferably with a length of 6 mm, are preferably used. used.
  • the fiber length should in particular be smaller than the cross-sectional dimensions of the first reinforcement strands or / and further reinforcement strands. In this case when the reinforcement grid is pressed into the poured concrete up to the stop against the spacers or when pressing in the lattice girders together with the spacers an even fiber distribution is maintained in the concrete. With longer ones Fibers would compress in the direction of insertion before the reinforcement strands result, while behind it a lack of fibers favoring the formation of shrinkage prevails.

Concrete slabs with a reinforcement grid formed in this way can be in with high accuracy produce relatively small thickness because of the spacers that are necessary anyway and connecting elements no additional reinforcement strands to form a reinforcement grid must be provided.

Due to unwanted overload at Concreting, e.g. Cracks formed by using compaction equipment can be rearranged become.

  • the spacer parts can have a low tensile strength.
  • the concrete tensile strength can be activated within the mesh grid. By the opportunity to process the concrete components in the young state of the concrete slabs time can be saved.
