USING FIRED WALL TILE’S SCRAPS IN FLOOR TILE BODY

Abstract

The effect of the addition of the fired wall tile’s scraps in floor tile body was studied. The fired wall tile’s scraps were added to floor tile body according to 1.96-5.66-10.71-17.85 wt. % ratios. The sintering behavior of the floor tile was evaluated by measuring the water absorption, fired shrinkage, dry shrinkage and fired strength. In addition, microstructure and phase analysis were investigated by scanning electron microscopy (SEM), energy dispersive x-ray (EDX) and x-ray analysis (XRD). Firing was carried out at 1189 0C for 40 min. in industrial type continuous kiln. It is seen that the addition of 5.66 wt. % of the wall tile’s scrap to the floor tile increases the fired strength value. In the XRD analysis, anorthite phase was observed which shows fired strength and chemical resistance.
