| Popis: | A previous study showed that clay can be replaced in part by sewage sludge ash (SSA) in tile manufacturing, but the strength of the resulting SSA/clay tiles was inadequate. To extend the resourceful reuse of sewage sludge and improve the properties of SSA/clay tiles, micro carbon powder (MCP) was incorporated as an additive in SSA/clay tiles in this study. Beginning with pure clay, 30 % of the clay was replaced by SSA and sintered at 1100 °C. Next, the effects of four different fractions of MCP (0, 1, 2, and 3 %) on the properties of the SSA/clay tile specimens were studied. The experimental results indicate that the addition of MCP improved the densification of SSA/clay tiles and that 2 % MCP is the optimal additive concentration. When more than 2 % MCP was added, bubbles formed inside the tile body. These bubbles damaged the interior structure of the tiles, weakening them. |
