Title
(EN) METHOD FOR MANUFACTURING A BRICK, CERAMIC OR SIMILAR ARTICLE
(FR) PROCEDE DE FABRICATION D'UNE BRIQUE, D'UNE CERAMIQUE OU D'UN ARTICLE SEMBLABLE
Abstract
(EN)
The invention relates to a method for manufacturing a brick, ceramic or similar article. Traditionally the manufacture of bricks, roofing tiles and pipes has been an energy intensive process. Increasing commercial and environmental demands are drivers to reduce energy requirements the generation of so-called greenhouse gasses. By the addition of finely milled glass, as a fluxing agent, the firing temperature has been reduced. This has had the added benefit of reducing fluoride emissions from the articles during firing. The invention overcomes problems associated with the prior art by providing a method for manufacturing a brick or similar article comprising the steps of: producing a clay mix by mixing milled clay with a fluxing agent, forming the mix and firing it to produce finished brick or ceramic articles, characterised in that the clay mix is capable of being fired at a lower temperature.

L'invention concerne un procédé de fabrication d'une brique, d'une céramique ou d'un article semblable. La fabrication de briques, de tuiles de toit et de tuyaux est réalisée traditionnellement au moyen d'un procédé grand consommateur d'énergie. L'augmentation de la demande commerciale et concernant l'environnement représente une incitation à réduire les besoins en énergie, c'est à dire la production de gaz à effet de serre. L'addition de verre finement broyé, en tant qu'agent de fusion, permet de réduire la température de cuisson. S'y ajoute aussi l'effet de réduction des émissions de fluorure lors de la cuisson des articles. L'invention permet d'éviter les problèmes associés à la technique antérieure par mise en oeuvre d'un procédé de fabrication d'une brique, ou d'un article semblable, consistant à produire un mélange d'argile par mélange d'argile broyé et d'un agent de fusion, à façonner le mélange et à le cuire afin d'obtenir la brique terminée ou les articles en céramique, caractérisé en ce que le mélange d'argile peut être cuit à une température plus basse.
