Also, there is a drawback that white crystals are deposited on the surface of the inorganic board for construction by reacting with carbon dioxide gas in the air, resulting in a very poor appearance over a long period of time. Furthermore, even when paint is applied to the surface of a cement-based substrate, water may enter the interior through pinholes in the paint film, and free alkaline components inside react with carbon dioxide gas, resulting in efflorescence on the surface. There was a problem with coming.

The above object is achieved by forming a blast furnace cement layer 2 with a low free alkali component on the surface.

表面に積層一体化されている。The present invention will be described in detail below based on examples. The blast furnace cement layer 2 is formed by curing cement mortar or the like containing a large amount of blast furnace cement, and efflorescence does not easily occur due to the characteristics of the blast furnace cement, which has a small amount of free alkali components. As shown in the attached drawing, this blast furnace cement layer 2 is laminated and integrated on the surface of a cement substrate 1 such as asbestos cement or lightweight concrete board.

is formed, so efflorescence is less likely to occur and the appearance will not be impaired. Further, if a colored blast furnace cement layer containing a coloring agent is used as the blast furnace cement layer 2, the surface can be decorated, and the color will not easily fade or discolor even over a long period of time.
