alkali, synthetic mineral fibres, and with such fibers solidified cement products

摘要

Alkali resistant, synthetic, mineral fibres having the following composition on weight basis: SiO2: 42-50%, Al2O3: 8-13%, Iron oxides (calculated as FeO): 6-11%, CaO: 4-11%, MgO: 17-22%, TiO2: 0.5-3% and alkali metal oxides: 0.5-3.5%.
