Effectively eliminates cracks and fissures
The addition of Qfibre polypropylene fibres to concrete mixtures results in:
Almost complete elimination of shrinkage cracks and microcracks as possible entry points for water and for corrosive salt solutions. The elimination of shrinkage cracks in the concrete prevents the need for steel anti-shrinkage nets and improves the watertightness and reduces its seepage. You minimise the necessary costs.
Increased abrasion resistance of concrete
Increases the abrasion resistance of the concrete surface, as the closed concrete surface is more impervious to liquids that cause harmful corrosion of concrete or reinforced concrete.
Increased impact and shatter resistance by more than 15% ; by increasing the durability of concrete and reinforced concrete products using this effect in prefabrication by de-moulding precast products in advance (resistance to damage during transport).
Improved workability
Very importantly, the fibre significantly improves the workability of the concrete and the resistance to segregation of the components as well as the cohesion and homogeneity of the concrete; Evenly distributed in the concrete mass, the fibres reduce slumping of the heavier components and excessive water displacement in the form of cement slurry onto the concrete surface.
Frost resistance
Increased frost resistance and therefore no scaling of the concrete surface during use
Improved adhesion of mortars, e.g. plaster mortars. Guarantees very good mortar quality.
Reduces spalling
Improves the rheology of sprayed concrete leading to a significant reduction in spalling.
