Due to their characteristics, they have been widely used since ancient times and have been replaced by organic synthetic products such as plastics which have recently emerged in many fields. . However, the above characteristics are still not obtainable with organic synthetic products,
No substitute for ceramic products has emerged. On the other hand, the disadvantage of ceramic products is their weight. Efforts to reduce the weight of products have been made in many fields for many years, but there are many difficult problems in terms of materials, shapes, etc., and structural materials such as building materials still have sufficient weight reduction. Not planned. At present, with the spread of simple and lightweight construction methods and high-rise buildings, the demand for weight reduction of roofing materials, wall materials, flooring materials, etc. is increasing.
The demand for lightening of roofing materials, especially tiles, has recently been strong for prefabricated roofing materials. However, no ceramic building material product has yet been developed to meet this requirement. Metal plate,
Product which is said to new building materials of color best, etc. Ru have <br/> the mainstream. The weight of the traditional roof tiles, at most 40kg / m
The limit is about 2 and, for example, the weight required as a roof material of the prefabricated method, 30 kg / m 2, is unsatisfactory and has not been put to practical use at present. Under these circumstances, we tried to reduce the weight of ceramic building materials.
If you try to meet the strength, it is lightweight
There is a dilemma that it is difficult to satisfy the situation. In addition, conventional light
For the quantification method, specific minerals are added to the ceramic base,

And a method of forming a foam using a foaming agent.

ようとするものである。In view of the above, it is an object of the present invention to provide a light-weight, high-strength, easy-to-mold product to increase productivity as an industrial product, and firing with a glaze as a ceramic product. It is intended to provide ceramic building materials products that can be used.

粉を混入し、上記目的を達成した。Means for Solving the Problems The present inventor has made a unique idea completely different from the conventional method, using clays and cement as molding agents, and adding lightweight aggregate and glass powder as sintering aids. The above purpose was achieved by mixing.

の維持を図るものである。[0005] It is known that cement is not suitable for obtaining a molded article by firing after molding. On the other hand, it is also known that molding of cement is easy. Clays have been conventionally used as molding agents, but by firing,
Strength that cannot be obtained with cement products is obtained. The present invention utilizes the properties of both cement and clays, increased productivity based on formability by cement, but Ru FIG maintaining the strength by clays.

て、不適格であった。The present inventors have conducted intensive studies and found that there is an appropriate range of each amount for exerting the effect of lightweight aggregate without losing the characteristics of each of cement and clay. However, they found that it was better to add glass powder. That is, the preferable composition range of each raw material is as follows. (A) A mixture comprising 45 to 75% by weight of lightweight aggregate and 55 to 25% by weight of a binder, and (B) a binder comprising 0 to 50% by weight of glass powder, 10 to 65% by weight of clay and 20 to 85% by weight of cement. Outside of these ranges, the above-mentioned properties to be obtained are lost. FIG. 1 shows the relationship between the composition of glass powder, clay and cement as binders and the moldability. The range surrounded by the thick line in the drawing is the range of the present invention. If the ratio is out of the range, the molding is inadequate, the strength is insufficient, or the material is melted during firing, and thus is unsuitable.
