In particular, the sewage sludge molten slag and the sewage sludge incineration ash have inconsistent physical properties because the composition is not constant at each production time, place, and plant, and moreover, they contain a large amount of iron and have a low firing temperature. Therefore, the utility value as a ceramic raw material is not found and the reuse is delayed, and it is used as a part of the construction material without back-processing as a disposal method or secondary processing such as use for civil engineering materials and concrete products. The current situation is that most of them are suffering from disposal.

ものを用いることが好ましい。The above-mentioned sewage sludge molten slag and sewage sludge incineration ash used in the present invention have been discarded as industrial waste as described above. Since 80 to 10% by weight of such sewage sludge molten slag and sewage sludge incineration ash are added, the amount of waste can be reduced. If the content of the sewage sludge molten slag and the sewage sludge incineration ash is more than 80% by weight, the physical property change at the time of firing is not constant and the production control becomes difficult, and the quality cannot be stabilized. Also,
If the amount is less than 10% by weight, it is easy to stabilize the quality, but the reduction of the amount of waste cannot be expected so much. It is preferable to use the sewage sludge molten slag and the sewage sludge incineration ash having a particle size of 5 mm or less.

If the amount is more than 0% by weight, it is easy to stabilize the quality, but the amount of the sewage sludge molten slag and the sewage sludge incineration ash is reduced correspondingly, and the amount of waste cannot be reduced. On the other hand, if it is less than 10% by weight, the firing temperature becomes unstable and the quality cannot be stabilized. It is preferable to use the selben having a particle diameter of 5 mm or less.

In this case, if the binder is more than 30% by weight, it becomes difficult to form continuous voids. On the other hand, if it is less than 10% by weight, the effect as a binder is not sufficient and the product characteristics cannot be obtained. It is preferable to use a powder having a particle diameter of 1 mm or less as the binder.

A base composition is obtained by adding 3% by weight. This base composition can be molded by using a press or a vibration molding device in the same manner as in a conventional ceramics manufacturing method, and can be fired in a temperature range of 1180 to 1000 ° C to manufacture a ceramic having desired continuous voids.
