It was necessary to form the moisture-absorbing / desorbing layer 21 composed of wallpaper, and the number of construction steps was increased, which was troublesome, and the space 13 was narrowed.
- the heat insulating layer 17 is formed of an inorganic heat insulating material such as foam mortar or perlite mortar.

- the reason why the solid content of the synthetic resin emulsion was set to 3 to 50 parts by weight with respect to 100 parts by weight of the cement is that the adhesive performance is reduced when the amount is 3 parts by weight or less, and the fire resistance is increased when the amount is 50 parts by weight or more. This is because the performance is reduced while the cost is increased.
- the reason for this is that if the amount is less than 1 part by weight, the heat insulation performance is reduced, and if the amount is more than 20 parts by weight, the fire resistance and strength are reduced, but the cost is high.
- the reason why the carbon fiber is used in an amount of 0.3 to 5 parts by weight with respect to 100 parts by weight of the cement is that the effect of reinforcing the matrix and the effect of preventing cracking due to shrinkage become lower at 0.3 parts by weight or less.

- the inorganic mic mouth valve and 100 to 200 parts by weight of the cement are used in the case of less than 10 parts by weight. This is because the ratio of other materials having high cost is increased and the cost is increased, which does not contribute much to the improvement of the fire resistance performance. If the content is more than 200 parts by weight, the material becomes brittle in strength.
