Abstract
A method and means for the stabilization of organic sludges that includes combining the sludge with Portland cement, fly ash, calcium sulfate dihydrate, and lime, optimally with stabilizing agents such as clay, recycled rubber, and asphaltene, and an adsorbent for organic substances. The stabilized sludge compositions prepared in accordance with this method are characterized by a soil-like consistency and low-volume expansion relative to sludge volumes prior to stabilization.
