Abstract: The screening of the crushing of the open-hearth open-hearth slags is characterized by a delayed nature of hydration. At the same time, the gel structure of neoplasms is formed in time, as evidenced by: the invariance of X-ray diaphragms of hardening slag stone both at the age of two years; the presence on the surface of slag particles of gel-like gangue formations; heterogeneity at the microlevel of gel neoplasms both in the composition of the chemical elements and in the quantitative ratio of them; the appearance of syneresis characteristic for the gel cracks, their healing and the appearance of new ones, often intersecting old cracks. An effective way to activate the astringent properties of the dump open-hearth slag is to introduce into the slag water mixture a quick-drying ground lime.

Keywords: screening of crushing of open hearth slag, hydraulic properties, hydration neoplasms, activation of astringent properties of slag.
