An Effect of Aluminum Content on Characteristics of Spent Foundry Sand/Sewage Sludge Ceramic Support

抄録

An effect of aluminum content on characteristics of ceramic support is examined to obtain a high performance of ceramic support manufactured with the mixture of spent foundry sand/sewage sludge. Characteristics of ceramic support with aluminum content are estimated by bulk density, porosity, chemical resistance, and compressive strength. Forming of ceramic support is made with a compressed mold in this experiment. Sewage sludge is used after drying by oven. As the aluminum content is increased, characteristics of ceramic support are improved. Since porosity in ceramic support is decreased when aluminum content is more than 3wt%, aluminum content can be decided by 3wt%.
