Mineralogical and Technological Varieties of Argillaceous Materials for Ceramic Brick and Claydite Gravel

The classification of clay materials into mineralogical and technological varieties is developed to asses their suitability for the production of ceramic brick and claydite gravel. Materials are divided into seven varieties based on their quality. The identification of the mineralogical-technological variety of a clay material allows for a reliable prediction of the finished product quality without carrying out a large number of labor-consuming tests.
