Facing Tiles Based on Feldspar Material and Cambrian Clay from Chekalovskoe Deposit
- 17 Downloads
The possibility of using feldspar material from the Chupinskii mining and concentration works in mixtures for the production of ceramic facing tiles is considered. The effect of this material on shrinkage, water absorption, and strength of articles based on Cambrian clays from the Chekalovskoe deposit is studied, and their properties are compared with samples of the mixture used at the Nikol’skii Ceramic Works. The use of quartz-feldspar dust-removal waste makes it possible to exclude lime from the mixture composition and to decrease the quantity of quartz sand requiring milling.
