Abstract

Linvention concerne un procédé de synthèse non conventionnel pour la production d'ettringite à partir de phosphogypse, visant à valoriser ce sous-produit industriel. Ce processus transforme un déchet de l'industrie des phosphates en un matériau utile pour des applications telles que le stockage d'énergie thermique et la construction. En utilisant des techniques d'analyse avancées telles que DRX, MEB, FTIR, ATG, et DSC, la méthode garantit la formation effective d'ettringite, offrant ainsi une alternative économique au gypse traditionnel.
