Abstract

This paper shows that immobilization of industrial and hazardous wastes in cement-based grouts is technically feasible and offers an improved method of waste disposal. Experiments were performed on four simulated waste streams immobilized in cement-based grouts: (1) fly ash; (2) spent limestone scrubber solids; (3) pickling liquor and recovery sludge containing arsenic, cadmium, chromium, copper, manganese, and lead; and (4) a vacuum pump oil containing polychlorinated biphenols (PCBs), Lindane (hexachlorocyclohexane), pentachlorophenol, and 9-9′-dichlorofluorene. The classes of organic compounds represented by this fourth waste are (1) PCB, chlorinated cyclohexane, chlorinated phenol, and PNA, respectively. Leach tests were performed with a simulated ground water typical of aquifers found in Maryville limestone.
