1. Introduction.Alkali-activated binders have been widely discussed and promoted as a component of the current and future toolkit of ‘sustainable cementing binder systems’ , , , , , , .These binders, sometimes also named ‘geopolymers’ , can be generated from a wide range of aluminosilicate precursors, with differing availability, reactivity, cost and value worldwide.
