This paper investigated the effects of mechanical activation of fly ash (FA) from thermal power plants on physical-mechanical properties and structure of geopolymers. FA from different power plants in Serbia was mechanically activated in planetary ball mill. Geopolymerization was conducted by use of sodium silicate (water glass) at elevated temperature (95 degrees C) for 4 h. It was observed that mechanical activation of FA for 15 mm resulted in drastic increase of geopolymer compressive strength (in all cases >1000%). High strength values were associated with improved FA reactivity obtained mainly by the reduction in particle size and reduced water/binder ratio.
