Abstract (en)
[origin: WO2011157939A1] The invention relates to a filter structure, for filtering particulate-laden gases, comprising a plurality of honeycomb filtering elements, said structure being obtained by assembling said elements, which are joined together by means of a joint cement, said joint cement being an essentially inorganic, preferably mineral, composite comprising at least, by weight and with the exclusion of water and of the optional organic additives; between 30 and 95% of a filler formed by an assembly of grains, the melting point of which is above 1000°C, said grains having a diameter of greater than 30 micrometres, between 5 and 70% of a binder matrix incorporating a geopolymer phase, said binder matrix comprising, in percentages by weight of the corresponding oxides: SiO2: between 20 and 80%, A12O3: between 3 and 50%, R2'O: between 3 and 30%, R2'O representing the sum of the alkali metal oxides present in the binder matrix.
