What is Alkali Resistant Glass Fibre?

Hydrating cement is strongly alkaline and a concrete matrix will rapidly degrade normal E Glass Fibre, as used with polyester resin in GRP/FRP products. AR Glass Fibres have been specially formulated to resist this degradation by the addition of zirconia to the glass fibre composition. The European standard BS EN15422 2008 calls for a minimum zirconia content of 16% – Fibratec fibres exceed this requirement.

Why Use Alkali Resistant Glass Fibre?

Concrete used for ground supported slabs has traditionally been reinforced with a light weight steel mesh. It has always been difficult ensuring that the mesh is correctly placed within the section and the reason for the use of the mesh is often questioned.

AR Glass Fibres can act as a replacement for steel mesh.

These fibres disperse uniformly throughout the mix and, at the correct dosage level, can control plastic and drying shrinkage cracking.
