| This Investigation was carried out to incorporate fly ash, a waste
material generated from thermal power stations, as a replaceˇ
ment of sandstone and to some extent feldspar in the earthenˇ
ware type glazed wall tile body composition. Test specimens of
eight different body compositions incorporating fly ash were preˇ
pared and fired at five different test temperatures, viz., 1000°,
1050°, 1100°, 1150° and 1200"C in an electrical furnace. Dry and
fired properties like dry MOR, fired shrinkage, fired MOR, appaˇ
rent porosity, water absorption, bulk density, thermal expansion
of the optimized body and glaze etc were determined and compared
with those of the specimens of a traditional earthenware
tile body used as a standard composition. It was observed that
the incorporation of fly ash in the tune of 30 wt% was the optiˇ
mum in achieving the requisite thermo-mechanical properties
in wall tile body. |
