A Study on Solidification of Sludges with Portland Cement

Abstract

The treatment and disposal of sludges being one of wastes present a social problem in many localities. The authors conducted an experiment on solidification of sludges with Portland cement. The sludges were collected at Shibaura, Odai, Sunamachi and Ukima sewage treatment facilities, and Tokyo Bay in Tokyo. As the results of the experiment, this paper described the relation between compresive strength of solid matrices and mixes of varying proportion of sludge, Portland cement, and water.
