The present invention relates to a cementitious plate material composition with decorative stones and a method of manufacturing the same. More particularly, the present invention relates to a cementitious plate composition comprising a cementitious composition formed by a cement composition into a tile-like plate material, The present invention relates to a cementitious plate material composition and a method of manufacturing the same.

There are various methods for decorating the outer wall of a building such as a building. Typically, however, there is a method in which the surface of the outer wall of the building is closed with a cement composition and painting is performed by a technique such as spraying or scattering with a paint or a pigment composition, A decorative plate such as a stonewall or a tile including a decorative sheet is adhered to a surface of an outer wall of a building using an adhesive to decorate the decorative plate.

The method of painting with a paint or a pigment composition is advantageous in that it is easy to work, requires a relatively low cost, and can perform work in a short period of time. On the other hand, these paints and pigment compositions can be easily contaminated, There is a drawback in that it is necessary to paint again regularly.

On the other hand, the method of fixing the decorative plate is difficult to work, requires a relatively large cost, and takes a long period of time. However, even if contamination is reduced and contamination is caused, It is widely used because it has the advantage of being able to produce decorative effects relatively permanently.

The decorative plate mainly used for fixing the decorative plate includes a stone plate processed into a plate shape of a natural stone such as marble and a tile artificially manufactured through a sequence of forming-drying-glazing-firing-firing-post- Is used.

Particularly, in the case of tiles, since the color is relatively freely produced and artificially produced by the selection of the glaze, the quality of the product is uniform, and since the product can be mass-produced in a standardized form, it is widely used , It is pointed out that the appearance of the building is uniform because it is a mass-produced product, and it can not be distinguished from other buildings.

On the other hand, in the case of a natural stone plate such as a marble plate, a naturally produced rock material is cut and grinded into a plate, and the quality of the product is not uniform, the price is relatively high, Because it is a product that is produced naturally, it has the merit of excellence in ornamentation such as giving distinctive natural beauty to a building and differentiating it from other buildings because it is difficult to realize the same appearance in different buildings have.

In addition, although concrete and gravel are mixed and cured, they are cut into plates and there is a plate made of plate material. However, it is difficult to cut concrete including gravel, and the gravel is partially broken off from the concrete There is a problem that the decorative property is deteriorated due to problems such as formation of an empty space.

Therefore, a decorative plate having a natural quality such as natural stone and having a uniform quality was required in the construction industry.

It is an object of the present invention to provide a cement board composition with decorative stones that can impart natural ornamental qualities to a building.

Another object of the present invention is to provide a cementitious plate composition having decorative ornamental stones mounted thereon, and a decorative layer coated with a colored layer for imparting hue to the surface of the plate material itself.

It is still another object of the present invention to provide a method of manufacturing a cementitious plate composition having decorative ornamental stones capable of imparting natural ornamental properties to a building.

FIG. 1 is a perspective view schematically showing a cementitious plate composition to which a decorative stone is attached according to the present invention.
