Generally, a building is completed by constructing a skeleton with concrete as an apartment, a house, an industrial building, etc., and cement mortar on the surface thereof. The cement mortar causes a sick house syndrome because many harmful substances such as formalin and heavy metal are generated, Asbestos dermatitis, allergic rhinitis, headache, respiratory diseases, etc. are occurring. Due to materials harmful to human body such as styrofoam, asbestos, urethane foam, lacquer, paint and adhesive used in various construction finishes, There is a serious problem.

In recent years, it has been known that radon is generated in a gypsum board which is widely used as waterproof, fireproof, and incombustible interior material in buildings, and it is shocked to consumers. Radon can cause cancer as a radioactive material and has a long half life It does not disappear over time, such as formalin, but the problem is serious because it is continuously released during the period of inhabitation.

Therefore, many attempts have been made to solve these problems. The most common of these is the use of natural materials that can replace cement as a plaster, and a representative example is a loam sheet This is an attempt to solve the sick house syndrome problem by attaching to the inside of the cement wall.
