Features of Chemical Compositions of Argillite-like Clays and Argillites
The characteristic of the chemical composition and structural features of stone-like argillous raw material which includes argillite-like clays, argillites, clay-slates, siltstones and transitionalvarieties of these types of rocks is presented. The substantiation of a specific set of rock-forming elements in the composition of this raw material thatdetermines the suitabilityof this raw material for manufacturing building ceramics is made. Ceramic and technological properties are presented. It is revealed that the chemicalcomposition of argillite-like claysand argillites favors the obtaining, on their basis, roof tile, facing, wall, and road clinker bricks that makes this raw material enough promising.
