Results of the experimental study of products of the hydration reaction of saponite-containing wastes separated from the circulating water suspension of the kimberlit ore enrichment process are presented. Preliminary the saponite-containing material was subjected to mechanical activation till the specific surface of over 35000 m2/kg at the planetary ball mill. It is established by the methods of IR-spectroscopy and scanning electronic microscopy that sub-microcrystals of hydrosilicates of tobermorite group are present in the experimental sam- ples of the binder with a mineral additive of high-disperse saponite-containing material. It is proved that the mechanical activated saponite-containing material is able to form hydrosili- cates of additional generation in the process of concrete hardening. The data obtained make it possible to consider the saponite-containing material not only as a sorbent optimizing the structure formation by means of sorption of the water phase in the process of concrete hardening but also as an active mineral component in binder compositions of a hydration type of hardening.
