摘要
Glass fibers are disclosed, the fibers being formed of a glass composition containing the following ingredients in the weight percentages indicated below: SiO2: 25 to 54% Al2O3: 20 to 40% MgO: 24 to 40% ZrO2: 1 to 5% P2O5: 0 to 10% TiO2: 0 to 10% B2O3: 0 to 10% F: 0 to 5% Cr2O3: 0 to 2% It is disclosed that the sum of 2MgO+Al2O3 is equal at least to 70% of the composition. The use of such fibers in cementitious products is disclosed.
