<p>Catalyzed hydraulic mixtures containing inert materials which are mainly, preferably fully, constituted by inert materials recovered from building demolition processes, and being ground and granulometrically separated to a range of 0.05-30 mm, and used in an amount from 20% to 60% by volume, blast furnace slags and/or blast furnace ashes, having a granulometry in a range of 0.05-3 mm used in an amount from 10% to 25%, ashes derived from burnt waste materials, for example urban waste materials or the like and comprising both heavy and light ashes with a granulometry in a range of 0.05-15 mm, used in an amount from 10% to 70%, wherein the catalyzers are selected to provide a basic environment with at least a pH 11, thereby the included salts can be recrystallized, with a consequent confinement of the polluting substances included in the slags. With said mixtures can be made non polluting articles.</p> |
