FIELD: chemistry.
SUBSTANCE: invention relates to the industry of construction materials and specifically to making foamed concrete. The method of making structural heat insulating foamed concrete involves mixing water, a silica component, binder, addition of a water-aluminium suspension while stirring, putting the obtained foamed concrete mixture into a mould and steam curing. The silica components used is expanded perlite and vermiculite, taken in mass ratio 1:2 - 2:1, crushed and screened through a net with 0.63 mm openings.
EFFECT: improved heat insulation properties of foamed concrete.
