FIELD: construction.
SUBSTANCE: invention relates to production of construction materials and can be used in making lining of units operating under high temperatures and high cyclicity. Heat-resistant slag-alkaline concrete produced from concrete mixture, containing chamotte of 5–10 mm fraction, chamotte of less than 5 mm fraction, self-breaking ferrochrome slag, sodium hydroxide, portland cement and water, where the mixture additionally contains slag of metal chromium of 5–10 mm fraction, slag of metal chromium of fraction less than 5 mm and metakaolin in following ratio of components, wt%: chamotte of fraction 5–10 mm - 15.0, chamotte of fraction less than 5 mm - 16.0, slag of metal chromium of fraction 5–10 mm - 15.0, slag of metal chromium of fraction less than 5 mm - 15.5, self-breaking ferrochrome slag - 23.5, caustic soda - 2.5, portland cement - 1.0, metakaolin - 0.5, water - 11.0.
EFFECT: technical result is provision of application temperature of more than 1400 °C with preservation of strength characteristics.
