FIELD: construction.
SUBSTANCE: invention relates to the field of production of construction materials, in particular, an analogue of granulated foamed glass-filler of artificial porous, used as a filler in the preparation of light and silicate concrete, as well as fillings for heat insulation of roofs, walls, coverings, floors of lower floors of buildings and structures for various purposes. Filler porous for light concrete contains the following, wt%: thermal power plant slag 35–40, scrap glass 37–42, sodium liquid glass 10, glycerine 4, crystalline decahydrate of sodium tetraborate 5, water 4.
EFFECT: reduced foaming temperature up to 800–830 °C and foaming time to 15–20 minutes, recycling wastes.
