Abstract (en)

[origin: WO9961373A1] The invention concerns an extrusion product containing hydrated lime, in the form of a calcined extruded product containing at least a binding agent capable of withstanding the extrusion product calcination temperature. Said product is prepared by dry process mixing of hydrated lime, at least said binding agent and a plasticising agent, gradually incorporating water in said mixture so as to obtain a paste capable of being extruded, extruding said paste into said extruded product, drying and calcining the dried extruded product at a calcination temperature higher than the plasticising degradation temperature and lower than the hydrated lime decomposition temperature.
