This paper investigates the influence of mechanical activation of different types of fly ash on the properties of alternative binders – geopolymers based on alkali activated fly ash. Fly ash was firstly mechanically and then alkali-acti vated. Mechanical activation of fly ash was conducted in a planetary ball mill. Alkali activation of fly ash was carried out at room temperature by use of so dium silicate solution as an activator. Structural changes of geopolymers were assessed by SEM and EDS analysis. Mechanical activation of fly ash led to a significant increase in strength of these alternative binders, thereby expanding their potential application, such as soil stabilization.
