Influence of the cement type on the stabilisation of fly ashes from municipal solid waste incineration

Municipal Solid Waste Incineration Residues (MSWIR) and specially fly ashes (MSWFA) from gas cleaning devices contain dangerous salts and toxic ions, which may be released to the environment. Therefore, fly ashes must be stabilised before their landfill. In this paper the influence of cement type on the stabilisation of MSWFA from gas-cleaning devices is presented. The cements used were, Foundu calcium aluminate cement (CAC), ordinary Portland cement (OPC) and OPC with 80% replacement by ground granulated blast furnace slag addition (OPC/BFS). © 2000 Elsevier Ltd.
