The incineration of municipal solid wastes (MSW) generates fly ash, disposal of which could present serious environmental and ecological problems. Cement-based systems, especially Portland cement, have been used for immobilization of wastes before disposal. The leaching properties of major elements from stabilized municipal solid waste incinerator (MSWI) fly ash conditioned with ordinary Portland cement were investigated as a function of time up to {approximately}544 days using a Dutch tank leaching test, NEN 7345, and a modified form of this test in which pH was controlled by bubbling air through the leachant. In both cases a transition between short-term regimes of relatively rapid leaching and a longer-term regime, commencing after {approximately}10 days to 100 days, can be distinguished.
