Abstract:
Disposing of the sludge from sewage treatment plants creates environmental problems. These problems can be reduced if the sludge is put to a large-scale economical use. Research studies have been carried out to investigate an economical use for the lightweight aggregate produced by mixing and firing the sludge with clay as a concrete material. A series of laboratory experiments has been undertaken to compare the properties of concretes produced by using three different coarse aggregates, namely, normal weight crushed rock, lightweight shale, and sludge aggregate.
