КЕРАМИЧЕСКИЙ КИРПИЧ НА ОСНОВЕ НИЗКОКАЧЕСТВЕННОГО ГЛИНИСТОГО СЫРЬЯ С ДОБАВКОЙ ОТХОДОВ ФЕРРОСИЛИКОМАРГАНЦА

Abstract

The high cost of ceramic pigments contributes to the expansion of research on their replacement with large-tonnage industrial waste. Charge compositions based on low-quality clay raw materials with additions of wollastonite with a dispersion of 10 microns (OOO Tekhnokhim, Novosibirsk) and waste of ferrosilicomanganese deposited in bag filters (West Siberian electrometallurgical plant, Novokuznetsk) were tested. It was found that the introduction of 9 wt. % wollastonite and 5 wt. % waste in semi-dry pressing leads to a content of 15 wt. % wollastonite - 2M with a maximum specimen strength of 45.5 MPa and water absorption of 14 wt. %. Refusal to use the addition of wollastonite with an increase in the dosage of the waste to 10 wt. % made it possible to reduce water absorption to 11.5 wt.% without loss of strength. The color of the che-turnip is dark chocolate.
