FIELD: building material production in hydraulic and industrial building, particularly to erect bases for weirs, dams, as well as motor road beds and so on.
SUBSTANCE: composition comprises dewatered sandy deposits obtained during aluminous material production. The deposits include ferric oxide in amount of 30-75% by weight, aluminum oxide in amount of 10-40% by weight, silicon oxide in amount of 0.5 % by weight, titanium oxide, sodium oxide, phosphorus oxide and bound water in amount of 1-20% by weight. The deposits contain not less than 80% of particles having sizes exceeding 0.1 mm.
EFFECT: possibility of waste utilization and reduced costs of structure erection.
