Abstract:

This paper examines geopolymer formation and alkaline solution reactivity and metakaolin properties. Many geopolymer samples were made from two alkaline solutions and four metakaolins to study these effects. FTIR spectroscopy and pH values were used to study geopolymer structural evolution. The mechanical properties were measured by compression. The type and amount of siliceous species and non-bridging oxygen atoms impact alkaline solution reactivity. A poorly reactive alkaline solution enhances metakaolin reactivity. Highly reactive reactions are governed by the alkaline solution. Thus, the alkaline solution's depolymerisation and metakaolin's reactivity determine geopolymer materials' polycondensation and compressive strengths.
