USING FIRED WALL TILE’S SCRAPS IN FLOOR TILE BODY

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). Samples were fired in industrial type kiln which was continuous production at 1189 0C in 40 minutes. It was determined that the addition of 5.66 wt. % of the wall tile’s scrap to the floor tile had an effect of increasing the fired strength value. In the XRD analysis, anorthite phase was observed which shows fired strength and chemical resistance
