Nucleation seeding in metakaolin geopolymers
… the dissolution of aluminosilicates in salicylic acid-methanol (SAM) solution. The SAM dissolution is a selective dissolution technique which has been used previously in our laboratory to remove calcium silicate hydrates from sodium aluminosilicate geopolymer product. This approach was …

Understanding effects of silicon/aluminum ratio and calcium hydroxide on chemical composition, nanostructure and compressive strength for metakaolin geopolymers
… 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 HCl extraction, …

Understanding the role of slag on geopolymer hardening and microstructural development
… geopolymer product were selectively dissolved by salicylic acid extraction method and hydrochloric acid respectively. These extraction methods revealed the presence of calcium silicate hydrate in the samples supporting the theory. The pore solution extracted from geopolymer at various time …
