Raman spectroscopy potentiality in the study of geopolymers reaction degree Open
Alkali‐activated materials (AAMs) and “geopolymers” are inorganic polymeric materials obtained by mixing of solid aluminosilicate precursors with an alkaline solution (generally, KOH or NaOH and Na 2 SiO 3 mixed in various ratios). This cl…
