Abstract: Aluminum dross residue is a by-product produced at secondary re-melt plants where aluminum scraps are recycled. In this study, aluminum dross residue was utilized as a major component in the fabrication of unglazed ceramics for wall tile applications. The use of this by-product can reduce the landfill and environmental problems.

Aluminum dross is a by-product of Aluminum production. At present, dross is processed in rotary kilns to recover the Al, and the resultant salt cake is sent to landfills; although it is sealed to prevent from leaching, the potential for leaching exists andcould harm the environment as the salt cake contains fluorides and other salts.

Oct 15, 2001· The question of the effect of concrete contact with aluminum drew some great responses. One respondent summed it up: "Aluminum and concrete don't mix, either in the plastic or hardened state." Aluminum reacts with the alkalis (OH) found in portland cement concrete. When these two chemicals are combined, the reaction produces hydrogen gas.
