In an effort to extend the reutilization of waste foundry sand (WFS), we evaluated the use of WFS as a replacement for clay in tile manufacturing. The effects of WFS addition on the properties of clay tile specimens were investigated at six different levels of WFS replacement: 0, 10, 15, 20, 40, and 60%. These specimens were fired at one of three different kiln temperatures: 1,000, 1,050, and 1,100°C. Various physical analyses were performed to determine the properties of the finished tiles. The results of this study indicate that the properties of the tile specimens were improved by WFS supplementation and that the optimal clay replacement level was 15% WFS. |
