AbstractIn this paper, it is presented the effect of Hydrothermal Treatment (HT) of ash from the incineration of municipal solid waste (MSWIA), classified as hazardous waste and industrial by-products such as coal combustion fly ash (FA). The most interesting results here presented they show that practically 100% of chloride ion content of some of these materials disappears after the hydrothermal treatment of the solid; they are also formed so important phases as tobermorite, C-S-H gel, belite etc, with cementing character. This treatment allows, therefore, valorise these wastes in cement-based materials and its application in the construction sector.
