Fly ash-based geopolymer: clean production, properties
Fly ash-based geopolymer concrete completely moves away from OPC and the high CO 2 emission associated with OPC production (Cakir and Akoz, 2008, Aldea et al., 2000, Habert et al., 2011). Fly ash-based geopolymer itself is a good binder that can be used as cement to mix with aggregates to produce the geopolymer concrete.
