Aluminum anodizing factories produced considerable quantity of sludge. If this sludge repulses in ordinary ways, it will create bad environmental problems on water source, soil, plants and animals and also it will cause diseases such as Alzheimer on human. The goal of this research is finding the applications for utilizing the sludge cake of aluminum anodizing units in order to prevent environmental pollution and finding economic profit for the factories. For this purpose, bricks with different combination of sludge, clay and sand were made. In next step, bricks were tested with available standard. The result showed that bricks with combination of 40 percent sludge have best and nearest quality standardized parameter of ordinary inner bricks. These bricks have lighter weight than the bricks in same bulk and cheaper price and also prevent sludge spreading in the environment.
