A cement-stabilized MSWI fly ash w as leached according to the diffusion test NEN 7345. The influence of carbonation during leaching was tested by bubbling N-2, air or CO2 through the leachant. The original test, where no gas is bubbled, was used as a reference. The periodically renewed leachant was analysed for its ionic concentrations. Porosity measurements, XRD and scanning electron microscopy (SEM) analysis were performed.
