Sludge Ash as Fine Aggregate for Concrete Mix
Publication: Journal of Environmental Engineering
Volume 121, Issue 9
Abstract
In metropolitan areas and highly populated cities the volume of sludge produced by wastewater treatment plants is enormously high. Incineration of sludge is a common practice to reduce its volume, through a burning process that converts it into ash. Still, a considerable amount of ash is produced, which creates serious disposal problems. Attempts have been made to study the feasibility of using sludge ash as a substitute for a portion of fine aggregates in concrete. The results indicate that it could be possible to replace up to 30% by weight of fine aggregate by sludge ash in a concrete mix for normal practice.
