2. Description of the Related Art Heretofore, a composition for a building material containing diatomaceous earth as a part of the composition has been used. When diatomaceous earth is dried and pulverized, it becomes fine particles equivalent to cement. Usually, this powder contains 80% or more silicic acid (silica), and is mostly amorphous and soluble. On its surface, countless fine holes (0.1 to 0.2 μm) are regularly arranged in a circular or needle shape. Due to this fine and ultra-porous structure, the surface area is large, and it exhibits excellent breathability, adsorptivity and deodorization. In addition, it has high thermal insulation, fire resistance, and is hardly chemically attacked.

By using diatomaceous earth as a material for building materials, excellent properties such as heat retention, heat insulation, prevention of dew condensation, humidity control and deodorization of diatomaceous earth are added to building materials.
However, the compositions and building materials described in the above publications harden diatomaceous earth with cement.
Therefore, the physical properties of the composition and the building material are close to those of the cement-based composition and the building material. For this reason, although the compressive strength of the building material after molding and solidification is as high as 40 to 60 kgf / cm 2 , the bending strength is as low as 5 to 10 kgf / cm 2, and the pH is 12 to 14 and the alkali is high, and weathering and so-called alkali There is a problem that discoloration of wood due to burning occurs.

[0006] The reason that the conventional composition to which diatomaceous earth is added is a cement system is that diatomite is not self-hardening, and therefore it is necessary to mix it with cement at a construction site to harden the diatomite to obtain a heat insulating material or a refractory material. Because of the large number, it was produced exclusively as a cement-based composition.

Since hemihydrate gypsum is acidic, the pH does not increase as in a cement-based composition using cement as a hardening material for diatomaceous earth.
The pH is about 4 to 5, and does not cause a problem as in a cement-based composition. However, if the pH is about 4 to 5, the finishing work may be oxidized and corroded.
It is preferable to add a small amount of cement as an adjusting material so that the pH becomes about 6 to 8 in a neutral region. in this case,
Since cement also acts as a hardening material for diatomaceous earth, the amount used is the number of the above-mentioned hemihydrate gypsum. In addition, hemihydrate gypsum does not have the possibility to block the pores of porous diatomaceous earth as in the case of using a resin emulsion as a hardening material. Furthermore, since the curing reaction is fast, there is an advantage that another overcoat can be applied on the applied mortar in a short time.
