Abstract

The invention relates to calcium silicate fibres having a glassy structure which are stable to the basic medium in concrete. These fibres have the following composition: from 10 to 60% by weight of CaO, from 35 to 75% by weight of SiO2, from 0 to 20% by weight of Al2O3, and a maximum of 2% in total of impurities of iron oxides and alkali metal oxides. The calcium silicate fibres described can have a small content of fluorine and phosphorus. They can be produced using the slags formed in the thermal production of phosphorus. The calcium silicate fibres described are advantageously used for the reinforcement of concrete.
