Geopolymer brick composite made from building demolition materials

Unlike most manufacturing recipes of geopolymer materials containing fly ash, the current work adopted the association of clay brick and concrete resulting from building demolition together with metakaolin and blast furnace slag as materials with cementitious and pozzolanic properties suitable for substituting the extreme pollutant-Portland cement.Except for the original composition of the material mixture, the authors have adopted their own curing regime of fresh pasta at 80 for 24 hours, followed by traditional storage at room temperature for 7-28 days.Geopolymer brick properties were excellent through the appropriate correlation of mechanical and physical features.
