A possibility to produce geo-polymer binders on the basis of fly ash of the Apatity TPS has been studies and proved. Main criteria of the efficiency of its use as an active component for producing alkali-activated binders are identified. Among them, the content of free CaO is less than 5% and a high concentration of the X-ray amorphous component (a glass phase) in the composition of ash-slag mixture – over 60%. It is established that the mechanical activation positively effects on the reaction activity of the fly ash when it is alkali activated by two types of alkali activators studied, in this case the most efficient agent for the fly ash of the Apatity TPS is NaOH.
