Larsen Fiberflex XT is a CE marked high performance polypropylene fibre specifically designed for use in ready-mixed concrete.
Larsen Fiberflex can be used a replacement for non-structural steelmesh. The addition of Larsen Fiberflex increases the tensile strain capacity of the mix at plastic stage and so reduces the tendency for plastic shrinkage cracking. As the rate of bleed is also controlled throughout the matrix, hydration is improved and permeability is reduced.
• Reduces plastic shrinkage cracking
• Improves durability
• Increases impact & abrasion resistances
• Reduces permeability
• Improves freeze/thaw resistance
• Improves fire resistance
