Abstract :

The purpose of this work is to assess the possibility of the recycling of some solid wastes of ceramic industry in the preparation of ceramic tiles at the same factory. Cyclone dust, sludge and filter dust were added to the base body in proportions ranging from 3.5 to 10% weight content. The mixed powders were pressed at 250bar, and then fired in an industrial kiln at 11000C for 30 minutes cycle. The results showed that addition of cyclone dust improved the physico-mechanical properties. The phase analysis via XRD and SEM demonstrated that the very rapid industrial cycle is insufficient for the complete melting of soda feldspar and the formation of any mullite crystals.
