Abstract

An investigation was carried out to incorporate fly ash, a waste material generated from thermal power stations, as a complete replacement of quartz and partial replacement of china clay and potash feldspar in the semi-vitreous tile body composition. Further, a non-conventional flux talc was gradually incorporated in the body mix containing 40 wt% of fly ash. Dry and fired thermo-mechanical properties of the fired specimens were studied and compared with those of a standard body mix. It was observed that the incorporation of fly ash to the tune of 15 wt% in the standard composition led to an increase in the fired strength by 14% without any increase to the maturing temperature of the specimens. The incorporation of talc in a body mix containing 40 wt% fly ash increased the fired strength by 32.4% and decreased the maturing temperature of specimen by 50°C in comparison to those of the parent body.
