摘要

The invention relates to an assembled ceramic body comprising blocks rigidly connected to one another by means of a joint, the side surface of the ceramic body being coverable with a peripheral covering, the joint and/or the peripheral covering comprising a hardened cement, having, on a cutting plane perpendicular to at least one of the surfaces opposite the blocks assembled by said joint, pores having an equivalent diameter of between 200 microns and 40 mm, hereinafter referred to as "macropores", in such an amount that, in said cutting plane, the total surface taken up by said macropores is more than 15 % and less than 80 % of the total observed surface. The invention can be used in the filtration of automobile exhaust fumes.
