Abstract

On utilise une pulpe de gel silicaté provenant du traitement de laitier de haut fourneau à l'aide d'acide résiduaire, cette pulpe étant rendue basique par addition de soude caustique et de l'aluminate de sodium provenant du traitement d'un gel d'alumine par la soude caustique et/ou d'aluminate de sodium obtenu lors du traitement de surface de l'aluminium, en incorporant à la silice de l'alumine en proportion définie par le rapport molaire de silice à l'alumine compris entre 60 et 1,2, de préférence entre 35 et 1,7.
