Abstract

It is expected that sewage sludge will continue to increase in the future as a result of the development of sewer construction activities. At present sludge is treated as industrial waste and buried, but the availability of disposal locations is becoming more limited every year. Sewage sludge is increasingly burnt or melted to reduce its volume, thereby forming a sewage sludge melting slag.<BR>The purpose of this study was the investigation of application of the sewage sludge melting slag to self-compacting concrete. An experiment involving the fresh and hardening properties was carried out, the results of which clearly revealed that the sewage sludge melting slag powder was a useful admixture for self-compacting concrete, and that the harding concrete characteristic is almost the same as for normal self-compacting concrete.
