FIELD: glass.
SUBSTANCE: invention relates to method of producing foamed glass. Batch for production of foamed glass contains following components, wt%: finely ground scrap glass 43–45; amorphous silicic rock 23–25; sodium hydroxide 11–13; aluminosilicate rock 4–6; water 13–17. Batch is stirred in intensive mixer, water is added in process of mixing to form sodium silicate hydrate with silica modulus 2.2–2.4 and batch is granulated. Granules are powdered with in moisture containing material loaded into metal molds with closed volume and subjected to foaming in furnace at temperature of 760–780 °C for 0.5–1 hour obtaining foamed glass, which is then cooled.
EFFECT: technical result is expansion of raw material base, simple technique, low foaming temperature, increased water resistance of foamed glass.
