に使用されている。[0003] Gypsum such as calcined gypsum (semihydrate gypsum) has the property of hardening in a few minutes when water is added, and is a hydraulic building material. Among the gypsums, anhydrous gypsum and dihydrate gypsum do not have hydraulicity by themselves, but change to calcined gypsum by firing or the like, and hydraulicity is obtained. The gypsum tile formed by putting wood fiber or the like in the calcined gypsum is lightweight and fire-resistant, so it is used for fireproof coating of structural members, flooring, roofing, and the plastered gypsum board, Used as wall, ceiling finish and base material. Gypsum boards made by mixing lightweight materials such as sawdust and perlite into calcined gypsum and pasting thick paper on both sides are used for ceilings, wall coverings and the like.

途や建物の土間を形成する用途には供されていない。In the above prior art, cement products such as concrete are difficult to handle because of their high specific gravity. Also, when air or lightweight material is mixed in to reduce the weight, it is difficult to mix due to a difference in specific gravity. In general, cracks tend to occur in concrete due to shrinkage, and it is difficult to reuse concrete waste. On the other hand, gypsum has a low specific gravity, and it is easy to mix air and lightweight materials for weight reduction. Further, gypsum is unlikely to shrink and cracks do not occur, so that a reinforcing bar is not required as a measure against cracks. However, gypsum is processed into a gypsum board, gypsum board, etc., and is frequently used for finishing walls and ceilings and as a base material, or as described in JP-A-5-222366, a dust-free type soil stabilization. Although it is used as a material, it is not provided as a hydraulic building material for use as a floor base material for buildings such as floor slabs or for forming soil between buildings. Further, plaster is generated as a large amount of waste when a building is renovated or demolished. The effective use of this gypsum waste material is described in the above-mentioned table 2000.
Although it is used in a method for producing a composite board and a molded body using gypsum as a base material described in Japanese Patent No. 504669, a gypsum waste material is used as a hydraulic building material, and the use of a floor base material and the floor of a building are considered. Not for use in forming.
