FIELD: construction.
SUBSTANCE: in a mould, vertically and at the distance of 20-50 mm from its side walls at least two metal reinforcement lattices are installed along the mould width with a pitch between them equal to 100-150 mm. The mould is filled with a mixture made of zeolite-containing tuff, a gasifier and a fluxing additive. The fluxing additive is a compound or a mixture of compounds containing sodium, concentration of which within the raw mix makes 4-12 wt %.
EFFECT: higher resistance of foam glass to damaging effects at least twice or thrice, reduction of foaming temperature and lower limit of glass density.
