2. Background. AAMs are synthesized by the reaction of an aluminosilicate-based precursor (xSiO 2 ∙ yAl 2 O 3), alkali activators (MOH and M 2 SiO 3; where M is either alkali ion Na + or K +) and water (H 2 O). No Portland cement is required to produce alkali-activated binders, but AAMs could also be added as a supplementary …
