Research of the structure and physical-mechanical properties of modified clay

The article presents the properties of natural clay in Uzbekistan. The historical analysis of the use of this natural raw material is presented. Possibilities of changing the properties of clay by introducing synthetic fibers of light industry waste into it are considered. Calculations of the properties of clay with the introduction of various additives and the technology of its processing are given. It has been established that modification of clay with fibrous waste and subsequent heat treatment improves frost resistance, and water resistance of the material, these properties depend on the percentage of fiber content, heat treatment temperature and time of holding the material in the furnace.
