“…Numerous types of wastes have been evaluated as alternative raw materials for brick manufacturing, including paper-making pulp (Maschio et al, 2009;Sutcu and Akkurt, 2009), steel slag (Cunico et al, 2003;Shih et al, 2004;El-Mahllawy, 2008), fly ash (Lin et al, 2006;Sarkar et al, 2007;Cultrone and Sebastián, 2009), water treatment sludge (Monteiro et al, 2008;Chiang et al, 2009), thin film transistor liquid crystal display optical glass (Lin, 2007;Dondi et al, 2009), processed tea (Demir, 2006), sawdust (Demir, 2008), and granite sludge (Acchar et al, 2006;Torres et al, 2009). The results of these studies indicated that the incorporation of wastes into the ceramic process is feasible at percentages ranging between 2 and 50%.…”
