Estimating the term…
An assembled ceramic body having blocks attached to one another by means of a seal, the lateral surface of the ceramic body possibly being coated with a peripheral coating, the seal and/or the peripheral coating including a set cement having less than 10% of inorganic fibers, as a percentage by weight based on the dry mineral matter, in a section plane perpendicular to at least one of the facing faces of the blocks assembled by said seal, having macropores with an equivalent diameter in the range 200 μm to 40 mm in a quantity such that the total surface area in said section plane occupied by said macropores represents more than 15% and less than 80% of the total surface area observed.
An assembled ceramic body comprising blocks attached to each other by means of a seal, the lateral surface of the ceramic body optionally being coated with a peripheral coating, the seal and/or the peripheral coating comprising a set cement, in a section plane perpendicular to at least one of the facing faces of the blocks assembled by said seal, having macropores with an equivalent diameter in the range 200 μm to 40 mm, in a quantity such that the total surface area in said section plane occupied by said macropores represents more than 15% and less than 80% of the total surface area observed, more than 50% by number of the macropores having an equivalent diameter in the range 500 μm to 5 mm.
