比較的付加価値の低い、土質改良材であるとか、セメン
ト混和材といった域に限られている。(Problem to be solved by the invention) However, the conventional method of using fly ash focuses on the self-hardening properties of fly ash, as mentioned above.
It is limited to areas with relatively low added value, such as soil improvement materials and cement admixtures.

て開発したものである。The present invention is characterized by the material properties of the fly ash, particularly that its composition contains S i 02 and Al 2 O, which are equivalent to clay, and that it is a hard silica-based mineral and has an extremely low specific gravity. In other words, it was developed with the aim of using it as an exterior material for buildings and other architectural structures with high added value, focusing on its light weight and extremely low cost.

Manufactured using existing high-quality clay as raw material. Therefore, it is very expensive and has the disadvantage of being heavy and having a large specific gravity. Therefore, if such heavy tiles or bricks are used in a building structure, it is necessary to increase the structural strength of the frame itself, which is a disadvantage from an economical design perspective.

In the examples, the raw materials kneaded as described above were granulated and then molded, but this molding method not only increases the yield of raw materials but also improves workability in the vibration molding process. Product costs will be reduced. Of course, an exterior material of the same quality can be obtained by kneading fly ash, polymer binder, perlite, and glass powder with the above-mentioned mixing ratio from the beginning without granulating the raw materials and molding by extrusion molding.
