る傾向が顕著であった。However, the conventional inorganic plate has a problem that the strength and durability are low because the porosity of the mixture of cement and aggregate is large. Also, when the inorganic plate is manufactured by a papermaking method, an aqueous slurry is prepared by dispersing cement and aggregate in water.However, since the porosity of the conventional mixture of cement and aggregate is large, the fluidity of the aqueous slurry is low. There was a problem. In particular, when ordinary Portland cement is used as cement and silica stone powder is used as aggregate, the average particle size of both is similar, and both have a sharp crushed shape, so the porosity tends to increase significantly.

が向上するのである。[0010] By using the inorganic powder material having a porosity of 30% or less, particles having a small particle size enter between particles having a large particle size to densify the internal structure of the inorganic plate. Thus, the bending strength and mechanical strength of impact strength of the inorganic plate can be improved, and the water absorption of the inorganic plate is reduced to improve the durability such as frost damage resistance. Further, by using an inorganic powder material having a porosity of 30% or less, the fluidity of the aqueous slurry can be improved, and even if the aqueous slurry is prepared with a small amount of water, the fluidity required for production can be improved. It can be secured. In addition, since the amount of water in the aqueous slurry can be reduced in this manner, the dewatering operation at the time of press molding can be easily shortened, and the productivity is improved.
