FIELD: chemistry.
SUBSTANCE: group of inventions relates to a concrete composition and a method for production thereof. Concrete composition contains blast furnace slag in amount of 200 to 500 kg/m3 based on the entire concrete composition, at least one of expanding additive and cement in amount of less than or equal to 22 wt. % with respect to blast-furnace slag, tempering water in amount of 130 kg/m3 or less, wherein precipitate of cone of concrete composition is greater than or equal to 40 cm. Invention also relates to a method of producing said concrete composition. Invention is developed in dependent items of the formula.
EFFECT: technical result is the development of a concrete composition with low environmental impact, having the same strength as the existing concrete, and having good flowability.
