Ha-Be PP-Faser 18µm FM
Polypropylene fibre for optimising concrete's fire resistance
Item No. 4503
FIELDS OF APPLICATION
Ha-Be PP-FASER 18 μm FP is an ultra-fine, synthetic fibre designed for reducing the crack formation in cementitious construction materials through improving its resistance to early age shrinkage cracking.
Additionally, Ha-Be PP-FASER 18 μm FP improves the fire resistance of concrete. At high rising temperatures, the fibre melts and forms micropores in the concrete which allow the vaporised water pressure to release. Concrete spalling can thereby be reduced or retarded.
- concrete applied in underground constructions (shotcrete and tubbing segments)
- basement walling
- pavements, internal and external slabs
- precast concrete elements
- screed, mortar and plastering
Having good dispersing properties Ha-Be PPFASER 18 μm FP can be dispersed easily, homogeneously and three-dimensionally throughout the fresh concrete.
The degree of fibre finesse and its frequency attains a homogeneous stress spread in concrete and minimises shrinkage and stress cracks significantly.
Ha-Be PP-FASER 18 μm FP improves concrete's bending tension stress, its impact strength and increases its ductility.
