Fly ash geopolymer concrete

WebGeopolymer concrete is produced using Flyash, GGBS, Fine aggregate and coarse aggregate and Alkaline activator Solution. The two main constituents of geopolymer are 1) The source materials which are rich in Silicon (Si) and Aluminium (Al) such as Fly Ash, Rice husk, Silica Fume, GGBS etc and 2) the alkaline liquids. WebMay 14, 2024 · The density of the fly ash and GGBS based geopolymer concrete specimens are shown in Fig. 5. With increase in density, there is an increase in the alkaline/binder ratio, and the maximum density was observed for the mix of 0% FA+100% GGBS. Maximum density was observed at alkaline/binder ratio 0.6 for all the combinations.
