Abstract The article reports on the study of thermal stability of alkali-activated aluminium-silicate composites (ASC) at temperature 800–1100°C. ASC were prepared by using calcined kaolinite clay, aluminium scrap recycling waste, lead-silicate glass waste and quartz sand. As alkali activator, commercial sodium silicate solution modified with an addition of sodium hydroxide was used. The obtained alkali activation solution had silica modulus Ms=1.67. Components of aluminium scrap recycling waste (aluminium nitride (AlN) and iron sulphite (FeSO3)) react in the alkali media and create gases – ammonia and sulphur dioxide, which provide the porous structure of the material.
