Why use AR Glassfibre?
AR Glassfibre is essential for GRC because of its resistance to the high alkalinity levels in cement. The fibres add strength and flexibility to the concrete resulting in a strong yet light-weight end product.
The alkali resistance of Glassfibre depends principally on the content of Zirconia (ZrO2) in the glass. The AR Glass fibre supplied by Fibre Technologies has a minimum zirconia content of 19%, the highest of any commercially available glass fibre.
Why is Zirconia Content Important?
Zirconia is what confers alkali resistance in glass. The higher the zirconia content the better the resistance to alkali attack. AR glassfibre also has excellent acid resistance.
