Abstract
In the scenario and panorama of waste re-exploitation and eco-sustainable geopolymer block production, the feasibility of total substitution of cement with fly ash in geopolymer blocks was investigated. Variations in characteristic parameters of ecological blocks concerning various molarities of alkaline activators were considered. The ideal molarity ratio prediction was 12 M. It was pragmatic that the better characteristics attained in the ecological blocks were optimal with a molarity of 12. Furthermore, 100% cement can be replaced with fly ash without affecting the strength criteria of geopolymer composite blocks by using fly ash and pond ash as fine aggregate. Usage of these blocks can reduce enormous amounts of CO2 emanation.
