The composition and properties of clays of the Tyumen region have been investigated in order to be used in the production of ceramic aggregate? keramdor. It was found that the clays are acidic, have a montmorillonite composition, are medium-dispersed, highly sensitive to drying and non-caking. Recommendations for the use of sample clay have been developed? 1 for the manufacture of ceramdor used for the construction of highways
