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.

Abstract
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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
