This paper examines the solidification/stabilisation treatment of two fly ash samples from a Municipal Solid Waste (MSW) incineration plant using a lime-pozzolan binder. The two examined fly ash samples were characterised by a high chloride and sulphate content and by a significant concentration of heavy metals. The effective development of hydrate phases during hydration of hydraulic lime-fly ash mixtures allows us to stabilise numerous pollutants in hardened pastes. The release of pollutants into the leachants is limited and decreases with the curing period of the pastes. |
