Fibrofor Multi
The well-known PP fiber for shrinkage crack prevention

The fiber against shrinkage cracks
The multifilament fiber Fibrofor Multi improves the properties of concrete, mortar and plaster components. It efficiently reduces shrinkage cracks in the early stages of the setting phase and in most cases replaces reinforcing steel in this area. Fibrofor Multi meets all the criteria and specifications required of pure, multifilament polyolefin fibers for plastic shrinkage reinforcement. Fiber distribution is of crucial importance. It is optimally guaranteed with our 6 or 12 mm long multifilaments. The dosage for underlayments/screeds is at least 600 g/m³ to max. 900 g/m³, for concrete constructions 900 g/m³. For increased fire resistance, a dosage of 2 kg/m³ is generally recommended.
Dosage
The recommended dosage für Fibrofor Multi is
- Reduction of plastic shrinkage Multi 127 / Multi 63 0,3 kg – 0,9 kg pro m3
- Passive fire protection Mulit 63 1,8kg pro m3
Application
