Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tile chamotte for roof tile debris, defective roof tiles, etc. disposed of as industrial waste (high-temperature sintered with crushed tiles, the same applies hereinafter), fly ash, waste glaze The present invention relates to a roof soil that does not dissolve in water and does not cause cracking while being effectively used, and has good workability on site.

[0002]

2. Description of the Related Art Conventionally, a fiber material is mixed with clay such as arakida, field soil, mountain soil, etc. at a site, and water is added thereto to stir the safety of the constructed roof tile (hereinafter referred to as a roof tile) and to secure the roof tile. Then, a roof tile fixed soil (roofing soil) was formed into a kneaded soil, and this roofing soil was used. Since the roof hardens relatively quickly and is mainly composed of clay, there is a problem that cracks are apt to occur due to shrinkage due to drying of the clay after construction. In addition, the construction of the roofing soil (sand nanban) mainly composed of sand and lime has problems in that the strength is heavy, but the construction is heavy, and the construction is difficult due to lack of viscosity.

In order to solve the above problems, for example, in recent years, there has been an invention of manufacturing and selling compacted soil in a plastic bag in a factory. (1) A roof soil composition disclosed in Japanese Patent Application Laid-Open No. 1-257157, which is intended to solve the conventional problems of on-site production. The content is such that the main material is a mixture of clay and sand, and lime, a coloring agent, a binder, a setting retarder and an appropriate amount of water are added and kneaded. Further, from the viewpoint of effective use and usefulness of resources (industrial waste), there is an invention in which roof soil is manufactured and sold in a plastic bag. (2) Japanese Patent Laid-Open No. 5-69000 is a method for producing roof tile fixed soil using waterworks sludge, which is an effective use of waterworks sludge. Its content is mainly composed of water supply sludge, mixed with slaked lime, fibrous substance, binder, and setting retarder with an appropriate amount of water to form a kneaded soil, which is then put in a special atmosphere such as a nitrogen atmosphere. Aging method.

[0004]

The conventional roofing clay containing clay as a main component has a large shrinkage and is therefore liable to cracks, and has a considerable problem in strength after drying. After the construction, the clay of the roofing soil may be eroded by rainwater such as a long rain, a thunderstorm, or a typhoon, and may collapse or melt and flow out.

[0005] In the technical document (1), since the main component is clay, the same problem as the conventional roofing soil can be considered. Another advantage is that it does not use industrial waste. According to the technical literature (2), the advantage of effectively utilizing industrial waste is beneficial. However, it is a water supply sludge and tends to vary in quality, viscosity, quantity, etc. under various conditions such as time or place, and it is not possible to secure consistency. Therefore, the lack of basic requirements for obtaining the material under certain conditions required, and the inconsistency in the quality of the material, etc., cannot be ensured, so that there remains uncertainty in ensuring the quality and quantity of the roof soil. In addition, it is a water supply sludge, and it may be a problem that requires special techniques and treatment in the production process.
