  • Method of producing geopolymer cement utilizing desulfurized red mud
    Patent number: 10407343
    Abstract: Red mud-based geopolymer compositions and methods of their preparation are described. The red mud-based geopolymer compositions can be cured at ambient temperatures using alkaline solutions of relatively low alkaline compound concentration compared to other geopolymer compositions. In particular, the use of a red mud previously utilized in a flue gas desulfurization process can provide high strength geopolymer compositions.
    Type: Grant
