Для дальнейшей утилизации они должны обладать н мыми техническими свойствами. Как один из основных факторов выступает химический и минеральный составы шлаков, оказывающие влияние на их конечные свойства. Элементный состав отвального доменного шлака ПАО «Запорожсталь», определенный методом электронно-зондового микроанализа, позволяет охарактеризовать фракции шлака с точки зрения токсичности. Элементы калий, натрий, сера, хлор, медь и титан, которые не входят в состав минералов, зарегистрированы сканирующим электронным микроскопом. Это позволяет предположить, что они сорбируются поверхностью минеральных частиц. Максимальное содержание калия, натрия и титана характерно для фракции 2,5 – 5,0 мм. Шлак содержит незначительное (менее 1 %) количество железа, титана и меди, которые относятся к третьему классу опасности вещества; это не препятствует дальнейшему использованию шлака. Определен третий класс опасности отвального доменного шлака. Гамма-спектрометрическим методом определены удельные активности и эффективные удельные активности гранулометрических фракций шлака. Обнаружены природные радионуклиды 40K, 226Ra и 232Th. Доказано, что шлак и его отдельные фракции относятся к первому классу радиационной опасности и могут быть использованы в строительстве без ограничений. Отвальный доменный шлак ПАО «Запорожсталь» характеризуется высокой гидравлической активностью с увеличением поглощения оксида кальция СаО во времени. Отвальный доменный шлак может быть рекомендован для производства вяжущих (портландцемента и шлакопортландцемента) по совокупности химических параметров: по отношению к умеренно опасным отходам производства, первому классу радиационной опасности и проявлению высокой гидравлической активности.</p></abstract><trans-abstract xml:lang="en"><p>Metallurgical slags accumulate in large quantities. For further disposal, they must have the certain technical properties. Among the main factors there are chemical and mineral compositions of slags, which affect their final properties. Elemental composition of Zaporozhstal dump blast furnace slag, determined by electron probe microanalysis, makes it possible to characterize the slag fractions in terms of toxicity. Potassium, sodium, sulfur, chlorine, copper and titanium, which are not part of the minerals, are recorded by scanning electron microscope; this suggests that they are sorbed by mineral particles surface. The maximum content of potassium, sodium and titanium is typical for the 2.5 – 5.0 mm fraction. Slag contains an insignificant (less than 1 %) amount of metals – iron, titanium and copper, which belong to the third hazard class of the substance; this does not impede further use of the slag. The third hazard class of dump blast furnace slag has been identified. Volume activities and effective volume activities of granulometric slag fractions have been determined by gammaspectrometric method. 40K, 226Ra and 232Th natural radio nuclides have been found. It has been proven that slag and its individual fractions belong to the first class of radiation hazard and can be used in construction without restrictions. Zaporozhstal dump blast furnace slag is characterized by high hydraulic activity with an increase in absorption of calcium oxide CaO over time. Dump blast furnace slag can be recommended for production of binders (Portland cement and slag Portland cement) in terms of combination of chemical parameters: to moderately hazardous production wastes of the first class of radiation hazard with manifestation of high hydraulic activity.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>отвальный доменный шлак</kwd><kwd>элементный состав</kwd><kwd>токсичность</kwd><kwd>класс опасности вещества</kwd><kwd>радиоактивность</kwd><kwd>природные радионуклиды</kwd><kwd>гидравлическая активность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>dump blast furnace slag</kwd><kwd>elemental composition</kwd><kwd>toxicity</kwd><kwd>hazard class of a substance</kwd><kwd>radioactivity</kwd><kwd>natural radionuclides</kwd><kwd>hydraulic activity</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Motz H., Geiseler J.
