USE OF BY- PASS DUST OF CEMENT INDUSTRY IN GLASS MANUFACTURE

摘要

The By-pass dust of Portland cement industry (ordinary or white cement) could be used in the glass manufacture as an alternative raw material instead of sand, partially or completely. The range of its percentage in the glass mixture lays between 10-70% of the total components. The other components are broken glass, the carbonates of each of the following: sodium, potassium, magnesium, barium, arsenic, and aluminum oxide and soda ash and coloring oxides such as the oxides of iron, cobalt and selenium. Blast furnace slag could be added on the account of the by-pass dust to obtain different colors.
