の機能を発揮する建築材料に関する。[Detailed Description of the Invention] [Industrial Application Field] This invention has superior moisture absorption and desorption properties compared to moisture absorption and desorption building materials, and can be used as an indoor building material to exert functions such as regulating indoor humidity and preventing dew condensation.

せしめていた。Since ancient times, earthen storehouses and wooden storehouses have been used as storage spaces to suit the local climate. These storage spaces were constructed using materials such as natural wood and clay paper that had the ability to absorb and release moisture, giving them the ability to adjust indoor humidity and prevent condensation on the walls.

ト高となる欠点があった。In modern RC buildings, it is not possible to fully utilize the moisture absorption and release functions of the earth and wood that are the structural materials for storehouses, and to compensate for this, wood such as cedar and fir is used as a double layer. It has been used as an interior finishing material for walls. However, wood has disadvantages such as aging deterioration of its breathing properties, poor fire resistance, poor dimensional stability, and high cost.
この発明は上記問題点に着目しなされたものであり、そ
の目的は湿度の調整、壁面結露の防止等の機能を発揮す
る吸放湿性が優れた建築材料を提案するにある。The present invention was made in view of the above-mentioned problems, and its purpose is to propose a building material with excellent moisture absorbing and releasing properties that can perform functions such as regulating humidity and preventing condensation on walls.
この吸湿性建築材料は、水硬性組成物からなった建築材
料において、水硬性組成物にゼオライトが混入してある
ことを特徴とする。This hygroscopic building material is a building material made of a hydraulic composition, and is characterized in that zeolite is mixed in the hydraulic composition.

性能はゼオライト単体の吸放湿性能に比べはるかに低い
ので、ゼオライトを組成物中に混入することにより所望
の機能を発揮せしめることができる。The moisture absorption amount of zeolite is as shown in Figure 1 and shows a considerably large value. Its amount is affected by temperature and water vapor pressure;
Above all, it has a strong temperature dependence, absorbing moisture as the temperature falls and releasing moisture as the temperature rises. Zeolite mixed into building materials made of hydraulic compositions such as cement or gypsum has lower moisture absorption and desorption properties than zeolite alone. However, in order to perform functions such as regulating indoor humidity and preventing condensation on walls, the moisture absorption and release performance required of building materials such as walls and floors is much lower than that of zeolite alone. By mixing zeolite into the composition, desired functions can be exerted.

硬化材した水硬性組成物を用いることもできる。In the case of a cement mortar whose main material is cement or sand as a hydraulic composition, zeolite is used in place of a portion of the sand. In the case of a cement mortar with a sand-to-cement ratio of about 2, remarkable moisture absorption and desorption properties can be imparted by replacing 10 to 50 inches of the sand volume with zeolite. In addition to cement, a hydraulic composition using gypsum or the like as a hardening agent can also be used.
