Abstract: The results of a comparative study of the dependence of the activity of alkaline binders on the ash and slag waste type of thermal power plants (TPP), the concentration of the alkali solution and the duration of hardening under normal conditions, with steaming and autoclaving are presented. It was found out that when hardening under normal conditions, the activity of binders is insignificant and is 2.5–12 MPa. With heat and moisture treatment, especially autoclave, it significantly increases. The activity of alkaline binders based on TPP slags is 1.5–2.0 times higher than the activity of similar compositions based on fly ash. Based on the developed binders, it is possible to produce steamed and autoclaved concretes, respectively, of grades 100–200 and 300–400.

Keywords: alkaline binders, fly ash and slag of thermal power stations, hardening under normal conditions, with steaming and autoclaving.
