Abstract
The invention relates to a process for the preparation of a shaped composite, comprising the preparation of a mixture into which fragments of mineral wool comprising a size comprising a sugar, a non-cement silica carrier distinct from the wool, a non-cement alkali metal carrier distinct from the wool, and water, are introduced, the non-cement silica carrier and the non-cement alkali metal carrier forming, with the water, a mineral binder which gradually solidifies around the solid particles present in the mixture, and then the shaping of the mixture into a shaped composite, in particular into briquettes. The invention also relates to a process for the manufacture of mineral wool, in which a molten mass is produced which is converted into mineral wool by means of a fiberizing device, the shaped composite being introduced as vitrifiable charge into a melting chamber, such as a cupola furnace.
