RAW MIX FOR MANUFACTURING CERAMIC WALL PRODUCTS Russian patent published in 2000 - IPC

FIELD: manufacture of building materials. SUBSTANCE: silicic dust is microsilica resulting from production of crystalline silicon, 56.3-75.8 wt. %. Alumosilicate component is CaCl₂, 21.9-41.5 wt.%. Prior to being molded, blend is granulated when directing aqueous solution containing 1.5-5 wt.% of alumina-processing waste in place of mixing water into granulator. Claimed raw mix makes it possible to increase strength of fired products by 3.0-3.5 times and to increase coefficient of constructive quality by 2.5-3.0 times. EFFECT: improved quality of the raw mix. 1 ex, 1 tbl
