The mineralogical composition and structure of shungite rocks of East Kazakhstan is investigated. The possibility of obtaining a dispersed modifier from shungite for the production of various building materials is studied. The structure of dispersed carbon-containing modifiers obtained in the process of «dry» and «wet» grinding of shungite is investigated. The possibility of modifying cement compositions with a carbon-containing modifier is studied. Due to the adsorption-bound water the modifier under examination ensures a sufficiently intensive process of hydration and structure formation of hardening cement stone. It predetermines the structure and physical and mechanical properties of the cement stone. The effect of dispersed carbon-containing modifiers on the structure formation and adhesion of bitumen to mineral materials is shown.
