Mineral construction materials play an important role in waste management. They are often used for solidification of hazardous mineral waste.These processes involve common cement or binders that apart from cement contain other mineral additive, which indeed are post-process by-products from other industries. Among approved mineral additives there is silica fly ash from hard coal combustion in conventional power plants. Such fly ash used during solidification allow formation of stable and durable matrices of high immobilisation potential for heavy metals.The paper presents analysis of effect of addition of fly ash on solidification process of galvanic sewage sludge in comparison to matrices prepared using Portland cement.
