<p>A fireproof panel comprises a mixture of reinforcing fibres, a hydraulic binder and mineral fillers. The reinforcing fibres are cellulose fibres of coniferous trees obtained from a chemical paste of the bleached Kraft type. Panels having a thickness greater than 50mm may be prepared by suspending cellulose fibres in water and forming a aqueous paste containing the cellulose fibres, a hydraulic binder and mineral fillers. The moist paste is deposited continuously in a layer on a moving filter member, is partially dehydrated and wound around a roll until the desired thickness is obtained. The roll obtained is then cut and unrolled and the hydraulic binder is allowed to harden.</p> |
