Title
(EN) A METHOD OF PREPARING A PUZZOLANIC MATERIAL FORM PAPER RESIDUE AND A METHOD FOR THE MANUFACTURE OF CEMENT FROM SAID MATERIAL
(FR) PROCEDE DE PRODUCTION D'UN MATERIAU PUZZOLANIQUE A PARTIR DE RESIDUS DE PAPIER, ET PROCEDE PERMETTANT DE PRODUIRE DU CIMENT A PARTIR DUDIT MATERIAU
Abstract
(EN)
The invention relates to a method for the incineration under precisely defined conditions, of kaolin-containing material such as waste paper and other residues stemming from recycling of waste paper for reuse in the paper industry, yielding a material of puzzolanic properties. To this end the incineration takes place in a fludized bed at a temperature of preferably 780 °C wherein the same or a lower temperature prevails in the freeboard. Due to its hydraulic properties the puzzolanic material is suitable for the manufacture of concrete of a high compression strength. The invention also relates to a cement containing the puzzolanic material manufactured by the method of the invention.
(FR)
L'invention concerne un procédé permettant d'incinérer, dans des conditions définies avec précision, un matériau contenant du kaolin, tel que des vieux papiers ou d'autres résidus provenant du recyclage de vieux papiers destinés à être utilisés dans l'industrie du papier, pour produire un matériau du type puzzolanique. A cet effet, l'incinération se fait dans un lit fluidisé, à une température qui est de préférence de 780 °C, la même température ou une température inférieure régnant dans la zone de revanche. Grâce à ses propriétés hydrauliques, le matériau puzzolanique obtenu peut être utilisé pour fabriquer un béton d'une grande résistance à la compression. L'invention concerne également un ciment contenant le matériau puzzolanique produit selon le procédé présenté.
