Fly Ash-Based Geopolymer Concrete [PDF]
Australian Journal of Structural Engineering, 2005 AbstractIn recent years, attempts to increase the utilisation of fly ash to partially replace the use of Portland cement in concrete are gathering momentum. Geopolymer concrete is a ‘new’ material that does not need the presence of Portland cement as a binder.

Bacterium amended 100% fly ash geopolymer [PDF]
AIP Conference Proceedings, 2019 The production of cement results in the release of a significant amount of solid waste materials and gaseous emissions. Actually this industrial sector is thought to represent 5–7% of the total CO2 anthropogenic emissions. In addition to the generation of CO2, the cement manufacturing process produces millions of tons of the waste product cement kiln ...
