Abstract: The paper considers the possibility of using slags of electric steel-making production in the construction of highways. At present, they are used much less than blast-furnace slags, which is associated with changes in the composition and properties of slags from electric steel-making production during their long storage in dumps. Studies were carried out on the slags of the Oskolsky electrometallurgical plant (OEMK). The properties of the slag OEMK current output and stale (5, 10 and 18 years of storage) and their changes over time were identified. The possibilities of the use of slag OEMK current output and stored in the dumps for several years as one or another component of the asphalt concrete mix (crushed stone, sand, mineral powder) are shown. It is shown that during long-term storage all unstable particles of the OEMK slag have time to disintegrate and disperse. Pieces of slag that did not crumble into powder are of interest as fine and coarse aggregate for asphalt concrete. The results of the study of the mineral powder based on the slag OEMK are given. It is shown that the addition of the dust-like slag fraction to OEMK as a mineral powder makes it possible to improve water resistance and long-term water resistance.
Keywords: electric steel slag, current output slag, dead slag, silicate decomposition, crushed stone based on OEMK slags, slag sand, mineral powder based on OEMK slags, asphalt concrete.
