FIELD: chemistry.
SUBSTANCE: invention relates to the industry of structural materials, particularly production of articles from foamed concrete, which can be used as protective shields for insulating building structures from high temperatures arising in case of fire, occupational accidents and equipment breakdown. The crude mixture for making foamed concrete contains the following, wt %: portland cement 52.06-57.73, foaming agent PB-2000 0.24-0.25, quartz sand with particle size of not more than 0.63 mm 7.99-18.56, liquid sodium glass 0.75-3.91, ground scrap sheet glass 2.00-10.31, water 23.96-24.75.
EFFECT: high heat-resistance of foamed concrete obtained from the crude mixture.
