steel fibres

KrampeHarex® steel fibres

Type KE 20/1,2 N
Type FT 20

Improve load-bearing strength.

This types are steel fibres that have been specially developed for use in laying concrete screeds. KrampeHarex® steel fibres for concrete screeds are equally suitable for use both in house building and in laying high-strength industrial floors. Unlike with thin wire fibres, there is no risk of injury from KE 20/1.2 N and KP 20/1,95, and the wear and tear on pumps and hoses is minimal.

PP-fibres

KrampeFibrin® PP-fibres

Type PM
Type PF

Avoid cracks due to shrinkage.

Because of their water retention characteristics, they have a significant effect on shrinkage where building materials are bonded together by cement. They do not conduct electricity and are completely alkali-resistant. Adding the fibres is extremely easy.

glass fibres

KrampeFibrin® glass fibres

Type G

Avoid cracks due to shrinkage.

The fibres significantly improve shrinkage behaviour where building materials are bonded together by cement. The main difference from the polypropylene fibres is in the increased tensile strength of the material.

Lay finer floors with KrampeHarex®
and KrampeFibrin®

Using steel mesh is particularly problematic on thin screeds. The reinforcement is generally laid in such a way that the load-bearing strength of the floor cannot be increased. Transportation, storage and installation can also often give rise to difficulties. With KrampeHarex® fibres for concrete screeds, these problems are a thing of the past. There is no longer any need to cut the mesh to size or transport awkward-shaped materials with difficulty to their installation site. The big advantage is that with the KrampeHarex® solution, there is no possibility of reinforcement defects and all that they imply.
