Understanding effects of silicon/aluminum ratio and calcium hydroxide on chemical composition, nanostructure and compressive strength for metakaolin geopolymers
… and to monitor the amount of the geopolymer gel, hydrochloric (HCl) acid extractions were performed. For geopolymers with calcium hydroxide, samples contained three phases: unreacted metakaolin, geopolymer gel and calcium silicate hydrate with aluminum substitution (CASH). In conjunction with the …
