Abstract
During the dismantling of coke ovens, large quantity of
silica waste was recovered and an investigation was undertaken
to find out suitable means to utilize these materials.
The use of silica grog for making brick was restricted due
to its high grain porosity and inversion of cristobalite at
lower temperature which seriously affects the bond strength.
Work was undertaken to develop proper composition
with suitable binders for making bricks utilizing the silica
waste. The bricks were made and tried in the ladles used for
transferring blown metal from Bessemer Shop to Open
Hearth furnace. Encouraging results were obtained in the
initial trials.
