r strand

Family: AR Glass macro fibers
Application: Structural concrete with fibres

Alkali-resistant glass fibre (AR) is especially used in prefabrication. Easy pumping and excellent finishes. Thanks to its density comparable to that of concrete and its adhesion to the matrices, it is the only fibre that improves compressive strength. Its material prevents the occurrence of corrosion and its high modulus prevents creep. Provides impact resistance. It also provides fire protection and insulating properties in specialised matrices.

Linear density TEX* (g/km)Length
r strand 3015030 mm
r strand 3643636 mm

*Because these fibres are made up of multiple filaments forming a strand, the diameter is more accurately expressed in Tex which is equivalent to grams per 1000 m of fibre.

Advantages

  • It provides residual, impact, compressive, abrasion and flexural strength.
  • Pumpable and suitable for polishing.
  • High chemical resistance and retains the density of the concrete.
  • Insulating properties.
