• A solid waste containing heavy metals from galvanic treatment has been stabilized by means of a binding matrix containing ?-2CaO•SiO 2, 4CaO•3Al 2O 3•SO 3 and CaSO 4 able to give calcium silicate and trisulphoaluminate hydrates upon hydration. Experiments have been carried out with mixtures containing up to 60% waste under three different points of view, as follows. The influence of the waste on the technical properties of the stabilized products, the leaching behaviour under four different conditions and the effect of the leaching medium on the binding matrix have been studied.

Abstract
• A solid waste containing heavy metals from galvanic treatment has been stabilized by means of a binding matrix containing ?-2CaO•SiO 2, 4CaO•3Al 2O 3•SO 3 and CaSO 4 able to give calcium silicate and trisulphoaluminate hydrates upon hydration. Experiments have been carried out with mixtures containing up to 60% waste under three different points of view, as follows. The influence of the waste on the technical properties of the stabilized products, the leaching behaviour under four different conditions and the effect of the leaching medium on the binding matrix have been studied.File in questo prodotto:
