Eefect of replacement of quartz by fly ash in tri-axial porcelain bodies

Betala, Saurav Kumar (2014) Eefect of replacement of quartz by fly ash in tri-axial porcelain bodies. BTech thesis.



Quartz is replaced by fly ash in tri-axial porcelain body. Three different batches were prepared with first batch being composed of normal porcelain composition and the other two containing fly ash with partial substitution of quartz and total substitution of quartz. Effect of this substitution was studied by measuring linear shrinkage, volume shrinkage, bulk density, apparent porosity, cold compressive strength and microscopy study by optical microscope. It was found that the fly ash incorporated sample shows better density and strength than normal porcelain sample. Also the optical microstructure of fly ash sample shows less porosity and more crystalline phase. This is mainly due to reduction in amount of quartz and increase in mullite content with fly ash addition.
