Ceramic brick from overburden breed of the Klyuchevsky field of sandstones
The results of laboratory studies to determine the suitability of clay raw materials of the Klyuchevsky Sandstone field for the production of ceramic bricks by plastic molding are presented. It is established that the introduction of the composition of the batch of associated lithoidal rocks as emaciated additives, coal and kaolinite-hydrologist Vladimirovskaya raw material fields, as well as adding the modifying additives that increase frost resistance, it is possible to obtain ceramic samples that meet the requirements of GOST.
