ない。2. Description of the Related Art Conventionally, in the production of building materials, base materials are selected for various purposes, and various materials are often blended with the various base materials. Among them, vermiculite (hill stone) is one of the mineral-based materials. This vermiculite is a clay mineral similar to biotite, and expands remarkably in a direction perpendicular to the layer due to dehydration at a high temperature, and expands like a hill to become a porous body. For this reason, it is excellent in heat insulation and sound absorption, so it is used for the compounding materials (filler, extender) to the base material, and also for various building materials such as heat insulation material and sound absorption material as the base material. Often used together. On the other hand, vermiculite does not have a very high hygroscopic capacity, and is therefore not considered as a humidity control material at all.

基材として用いられるものである。Therefore, as described above, when vermiculite is blended into a building material, expanded vermiculite is usually used for the purpose of weight reduction and the like. For example, it is used as a lightweight aggregate in cement products such as mortar and concrete. On the other hand, unexpanded vermiculite does not have the above-mentioned advantages such as weight reduction, and therefore, a small amount of up to about several percent is used as a base material for a special purpose utilizing its properties such as acid resistance and alkali resistance. It is just blended. Attempts have also been made to fix a board made of substantially unexpanded vermiculite as a base material to the back side of the inner wall, etc., to expand when a fire occurs, and to prevent fire spread. It is used as a specific base material used.

Among them, various studies have been made on building materials with humidity control (moisture absorption / desorption) and / or deodorization, and also with aesthetic appearance.
Nothing satisfactory has yet been found. That is, although these have obtained a certain result by using those having a large specific surface area, in particular, there are many cases where the water retention and the moisture retention are too strong and the moisture release rate is difficult.

In particular, as a result of studying to find a building material with an excellent balance in the amount and speed of moisture absorption and desorption, by blending unexpanded vermiculite with a base material, especially a hydraulic material that has a hygroscopic property but has an insufficient moisture release property. It has been found that the ability to release moisture can be significantly improved and the above-mentioned problems can be solved. That is, a building material was obtained by molding a building material composition in which unexpanded vermiculite was blended into a base material, and the blending amount was 5 to 70% by mass of the total composition (solid content).
