“Fly ash and GGBFS based powder-activated geopolymer binders: A viable sustainable alternative of portland cement in concrete industry”

Two types of powder-activated geopolymer binders having different proportions of fly ash and slag were used in this study. Engineering properties of geopolymer concrete of four different strength grades (40, 50, 65 and 80 MPa) were investigated in detail at ambient curing condition and compared with OPC concrete of same grade.
