SLUDGE ASH AS FINE AGGREGATE FOR CONCRETE MIX

The volume of sludge produced by wastewater treatment plants is enormously high in heavily populated areas. Sludge is usually incinerated to reduce its volume, converting the sludge to an ash. A considerable amount of ash remains, though, creating a disposal problem. The feasibility of using sludge ash as a substitute for a portion of fine aggregates in concrete has been studied. The results reveal that up to 30 percent of fine aggregates by weight can be replaced by sludge ash in a concrete mix for normal practice. The objectives of this paper are to: 1) determine the physical characteristics of sludge ash, 2) evaluate the utilization of the stabilized mixes for suitability in applications, and 3) evaluate the potential hazard to the environment as a result of ash stabilization in a concrete mix.
