Abstract

The purpose of this study is to manufacture sintered lightweight aggregate for non-structural concrete using sewage sludge, organic waste matter is produced to a sewage treatment plant. It is tested for basic property and strength of artificial aggregate according to addition ratio of sewage sludge, and the results are compared with imported aggregate from Spain. As the results of experiment, the manufactured lightweight aggregate could be used for non-structural concrete. Also, it was favorably comparable to those of the imported aggregate. When it is manufactured with aggregate, it is safe environmentally because of protecting elution of harmful heavy metals.
