Abstract
The effects of addition of a fly ash-marble waste mixture (2:1), in gradual replacement of sandstone and limestone, on the thermo-mechanical properties of traditional earthenware wall tile composition have been studied. Improvement in mechanical strength of the body was observed by addition of more than 22.5 wt% of the mixture as a substitute for sandstone and limestone at temperature of 1050 °C and above. In this temperature range, water absorption values of the body mixes exhibited a marginal variation (~1%). The improved results encourages the utilization of hazardous waste materials like fly ash and marble waste in the production of value added traditional ceramic product like glazed wall tile.
