METHOD FOR ALUMINOUS CEMENT PROCESSING

摘要

FIELD: construction. ^ SUBSTANCE: water mortar is produced from aluminous cement for which high-alumina slag produced from bauxite serves as raw feedstock. In the method for processing of aluminous cement intended for water mortar production, when it is tempered with water via oxidizing roasting, aluminous cement with particle sizes of 0.04-0.08 mm is subjected to specified roasting at temperatures 800-890°C. Oxidizing roasting is conducted in rotating pipe furnace with external or internal heating. ^ EFFECT: roasting temperature lowering with high value of sulphur oxidation degree. ^ 3 cl, 4 tbl
