A method for obtaining a finely dispersed fraction of ground blast-furnace granulated slag has been developed. The resulting material with the introduction of an alkaline additive can be offered as an alternative to foreign analogous fine-dispersed mineral binders, an example of which can be microcement. A comprehensive study of granular slags of two metallurgical plants was carried out, the physicochemical characteristics of materials were determined. The possibility of obtaining a fraction of ground granular slag with a particle size of no more than 16 microns using vortex electromagnetic homogenization and subsequent air classification is shown.

Samples of cement stone on the basis of two types of blast furnace granulated slag with the addition of fly ash by mechanochemical activation were made. Their chemical, phase and granulometric compositions, specific surface area, morphology, strength characteristics are investigated. An analysis of the influence of the method of introducing alkali on the performance of compressive strength was made.

Purpose The purpose of this paper is to study the fertility potential of the iron- and steel-making process waste granulated blast furnace slag to recover it as a beneficial product. Design/methodology/approach This slag fertilizer was mixed with organic fertilizer to enrich and dung the vegetable sets are pepper, lettuce and cucumbers. Findings In this study, 100 per cent granulated slag, 75 per cent granulated slag + 25 per cent fermented manure, 50 per cent granulated slag + 50 per cent fermented manure and 25 per cent granulated slag + 75 per cent fermented manure compositions were mixed with water and added to seeding pots. The growth rate of vegetable sets and also the level of contamination of heavy metals such as lead, copper, aluminum, mercury and cadmium were analyzed. The analyses results showed that contamination rates of lead, copper, aluminum, mercury and cadmium in lettuce and cucumber samples were in the range of acceptable levels for human health. Slag fertilizer enforced the set of growth rate and productivity, too. Originality/value By the recovery of the waste slag storage, transport and annihilation economical load on the industry would be eliminated, waste recovery contributes to the economical gaining and beneficial recovered products replace the need of fertility products.

В металлургическом производстве образуются технологические отходы (шлаки, шламы, пыль, окалина и другие), количество которых исчисляется в сотнях миллионов тонн. Одним из наиболее распространенных металлургических отходов является доменный гранулированный шлак, который при помоле приобретает гидравлические свойства и может использоваться как компонент вяжущего для цементных систем. Приведены результаты исследования свойств доменного шлака ПАО «Северсталь» (г. Череповец, РФ), а именно химический и фазовый состав предоставленных образцов шлака, а также индекс его активности по EN 15167 в зависимости от тонкости помола. На данном этапе исследований шлака не видится препятствий для использования шлака ПАО «Северсталь» в качестве компонента вяжущего в цементных системах. Показано, что с точки зрения прочности на сжатие и изгиб, а также расплыва стандартного конуса, который косвенно характеризует водоудерживающую способность вяжущего, предпочтительной является тонкость помола Sуд = 3 500…4 000 см2/г. Использование вяжущего, состоящего на 100 % из шлака, нецелесообразно без применения активатора. In the process of enrichment and smelting of metals, technological wastes (slags, sludge, dust, scale and others) are generated, the amount of which is calculated in hundreds of millions of tons. One of the local metallurgical waste is granulated blast-furnace slag, which, after grinding, acquires the hydraulic properties and can be used as a component of a binder. The results of studying the properties of blast-furnace slag of Severstal Iron and Steel Works (Cherepovets, Russia), namely the chemical and phase composition of the provided slag samples, as well as the index of its activity according to EN 15167, depending on the fineness of grinding are presented. At this stage of slag research, there are no obstacles to using slag from Severstal as a binder component in cement systems. It is shown that from the point of view of compressive and bending strength, as well as the spreading of a standard cone, which indirectly characterizes the water-holding capacity of the binder, the fineness of grinding 3500...4000 cm2/g is preferable. The use of a binder consisting of 100 % slag is not recommended without the use of an activator.

The effect of the degree of hydration and amounts of granulated blast furnace slag on the surface properties of Portland cement pastes were studied. The results obtained showed that the specific surface area SBET (m2/g) and pore volume Vp (cm3/g) decreased on increasing the degree of hydration. The addition of different amounts of granulated slag effected a decrease in SBET and Vp to an extent proportional to the amount present. These results were attributed to a replacement of clinker by the amounts of slag added and the formation of hydration products.
