Development of ceramic tiles from coal fly ash and tincal ore .
WEBJan 1, 2005 · The effect of coal fly ash and borax solid waste (TW) on the properties of wall tile was investigated. The properties examined include firing strength, firing shrinkage, water absorption and microstructure. A number of wall tile compositions were prepared by the replacement of potassium feldspar with the fly ash and TW in the range of 2–10%.
