Abstract
Alkali-resistant glass fibre comprises (in wt.%) 30-57 SiO2; 12-26 ZrO2; 14-26 R2O (where R = Na, K or Li); 1-11 R1O (where R1 = Ca, Ba, Mg, Zn or co); 0.1-6.0 CaF2; 0.1-10 M2(SiF6) (where M = Na, K or Li) and 0.1-12 B2O3. Additionally the compsn. may contain up to 3wt.% of TiO2, 3wt.% Al2O3 and 3wt.% Fe2O3. Fibres have a high alkali-resistance and are suitable for reinforcing cement, and have a low softening pt. The glass compsns. have low melt properties, e.g. glass liquifaction temps. between 750 degrees - 900 degrees C.
