Aerated concrete is a material widely used in Vietnam due to several advantages over heavy concrete. This article presents some results of experimental studies of the properties of aerated concrete produced using geopolymer binder from industrial waste generated in large quantities in Vietnam. The raw materials used included thermal power plant fly ash, blast furnace slag, ceramic powder, aluminum powder and an activating alkaline solution consisting of aqueous solutions of sodium hydroxide and sodium metasilicate. Testing of aerated concrete samples of the developed compositions was carried out in accordance with current Russian and Vietnamese standards. Experimental results confirmed the possibility of producing aerated concrete with a geopolymer binder based on large-tonnage technogenic waste, with an average dry density of less than 1600 kg/m3 and a compressive strength at the age of hardening of 28 days of 18.8–27.9 MPa. At the same time, aerated concrete containing 0.456 kg/m3 of aluminum powder and 50% wt. showed the greatest strength. blast furnace slag in the composition of the geopolymer binder, with a ratio of activating alkaline solution and active mineral additives equal to 0.4.
