Initial Raw Material and Corrective Additives for Production of Expanded Clay Gravel
For the production of expanded clay gravel and sand, which is commonly called expanded clay, natural low-melting argillaceous rocks are used, which when heated up to 1100-1250 °C can expand, as well as various additives that improve the technological properties of raw materials or enhance the quality of the final product. Expanded aggregates are manufactured practically throughout the entire territory of the Russian Federation.
