On the results of chemical and X-ray phase analysis, a higher reactivity of ground slag in comparison with the ash component of the ash and slag mixture of the Zuyevskaya TPP for obtaining alkali-activated binders and concretes based on it were established in this article. Since the determining factor for this is the almost complete amorphization of ground slag, especially its aluminosilicate component, which is largely crystallized in ashes. The compositions of concrete mixtures and concretes based on alkali-activated binders from ash and slag waste have been developed and its properties have been researched. The corrosion resistance of concretes based on slag and ash components of ash and slag mixtures activated by alkali – sodium hydroxide, in solutions of hydrochloric acid, sodium sulfate and magnesium chloride has been researched. High corrosion resistance of concretes based on binders from alkali-activated ground slag of thermal power plants has been established.
