The article investigates the drying properties of ceramic mass in the system “loesslike loam - ash of Ekibastuz HPP”. Ceramdor obtained from pure loam was selected as a control sample. A change in the structural and mechanical characteristics of ceramic masses during the drying process is associated with a change in temperature and moisture content of the material. The following results were obtained: molding moisture indicators, ductility numbers decrease with increasing ash. According to the classification of clay raw materials by plasticity, loam from a moderately plastic state goes into the category of low-plastic raw materials. With an increase in ash content of up to 20%, the sensitivity coefficient to drying leads to an increase in the time of crack appearance on the samples. A slight decrease in strength indicators is observed from 5.4 to 4.5 MPa. Thus, the results serve as the basis for the development of technological parameters in order to obtain ceramdor.
