でいてもよい。 The honeycomb body of the present invention is produced by bending a thin flexible cement-based sheet such as the above-mentioned cement paper into a honeycomb configuration shape, and bonding the honeycomb configuration contacts with a cement adhesive to form an organic substance-containing honeycomb body. It is manufactured by burning off organic components such as pulp. The honeycomb usually has cavities in the shape of polygonal columns, typically triangular, square or hexagonal columns. Although the size of the cavity is arbitrary, it is, for example, a polygonal columnar body inscribed in a circle with a diameter of several centimeters, typically about 1 to 10 cm in diameter. Cement paste, mortar, etc. are used as the cement adhesive. When the adhesive contains an appropriate amount of aggregate, such as mortar, the aggregate is aggregate powder that is thermally stable when fired at temperatures up to about 950°C, similar to the aggregate contained in cement paper.

The treatment is carried out at a temperature below 10°C, usually about 650°C to 900°C, for about 10 minutes to several hours, typically about 30 to 120 minutes. If the firing temperature exceeds approximately 950°C, it will be difficult to recover the strength even after subsequent rehydration. After firing, the honeycomb body is left in the air, for example by immersion in water, sprayed with water, etc., or preferably steam-cured to rehydrate and restore the strength by replenishing the moisture lost during firing. is normal. The organic components in the organic matter-containing honeycomb body are burnt off by the above firing process, making them non-combustible, and the rehydrated cement particles are added to the voids formed by the burned organic matter through the above rehydration treatment. grows.

The present invention is characterized in that the cement component in the honeycomb constituent material and the cement component of the adhesive are continuously bonded. It is essentially different from the conventional structure in which honeycomb paper is used as a core material and the surface is coated with an inorganic material such as magnesia cement, and the coating material is separated by the core paper. It is something. That is, the honeycomb body of the present invention has a structure in which cement and aggregate powder are continuously present in the honeycomb constituent material, and these are joined by a cement adhesive at the honeycomb constituent contacts. In other words, it is a cementitious honeycomb body in which cement and aggregate are continuously bonded, and is essentially a concrete, non-combustible honeycomb body.
