Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative material for concrete and a makeup method for a concrete skeleton using the same.

[0002]

2. Description of the Related Art The surface of a concrete skeleton constituting a wall surface or floor surface of a building generally has irregularities. Therefore, it is necessary to repair the surface. For example, as shown in FIG. 2 (a), when the surface roughness of the concrete skeleton 11 is relatively small, a thin coating is applied with a repair material 12 whose main component is cement containing aggregate with a small particle size, Further, a repair material 13 having a thickness of about 0.3-1 mm is formed on the entire surface by ironing to perform surface repair. Further, as shown in FIG. 2B, when the concrete skeleton 14 has a large roughness, a repair material 15 including an aggregate having a large particle size is used, and this is applied several times to apply about 30 times.
After applying a thickness of about a millimeter, the repair material 16 including aggregates having a fine particle diameter is formed by ironing the entire surface. After that, a color coating 17 containing an organic solvent as a main component is applied onto the repair materials 13 and 16 of the concrete skeleton according to the design, appearance, environment or use of the building.

[0003]

However, the conventional method of constructing a concrete skeleton has the following problems.
That is, in the conventional case, a thin coating or thick coating step with the repair materials 12 and 15 or an ironing step with the repair materials 13 and 16 is always required before finally performing the color coating 17 by paint or the like. . In order to perform color coating, it is impossible that these repair materials are not completely dried, and the pre-processes thereof may be prolonged depending on rainy weather. Furthermore, since ironing with a repair material is generally a manual work using a trowel, it takes much time and labor. Therefore, it is difficult to shorten the period and labor for applying makeup to the concrete skeleton, and the cost is accordingly high.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above conventional problems and provide a new decorative material for concrete and a method of making a concrete skeleton using the same. It is another object of the present invention to provide a makeup material for concrete which can shorten the makeup period of the concrete skeleton and reduce the cost, and a makeup method using the same. Another object of the present invention is to provide a decorative material for concrete that is friendly to the natural environment and the human body, and a method for making up a concrete skeleton using the same.

[0005]

The decorative material for concrete according to the present invention contains at least white cement, titanium oxide, powdered serpentine, and a pigment. More preferably, the decorative material for concrete contains an aggregate such as calcium carbonate and silica sand, and an admixture such as methyl cellulose. Further, it is desirable that the decorative material for concrete contains ordinary Portland cement. This is because when ordinary Portland cement is added, the pigment can be easily dispersed, and as a result, color unevenness and the like can be suppressed.

The method for making a concrete skeleton according to the present invention has a step of applying a decorative material for concrete containing at least white cement, titanium oxide, powdery serpentine, and a pigment on the concrete skeleton. This makeup method can also be performed after applying the repair material to the concrete skeleton. Further, the decorative material for concrete used here may contain ordinary Portland cement. Further, in this makeup method, the proportion of the pigment contained in the concrete decorative material may be adjusted to perform makeup having a desired color tone.

Since the decorative material for concrete of the present invention has a composition containing white cement, titanium oxide, powdered serpentine and a pigment, this decorative material is used for repair work by a conventional repair material and is applied thereto. It is possible to perform color painting such as paint at the same time. In other words, it is possible to omit either the conventional repair work using the repair material or the color painting. The decorative material for concrete of the present invention contains white cement to facilitate color matching with a pigment, and further adjusts the particle size of serpentine or aggregate to provide the same roughness and thin coating as the repair material. You can
In addition, the inclusion of titanium oxide has the advantage that the surface hardness can be enhanced and the denseness of the material can be improved. Furthermore, some customers may want the surface of the concrete to be rough.In such a case, the grain size of the aggregate or serpentine should be increased to a certain extent, thickly applied, and toned to give the concrete. It is also possible to provide a concrete surface with a natural roughness and a shade that matches it. Further, according to the makeup method of the concrete skeleton of the present invention, by performing the construction using the above-mentioned decorative material for concrete, it is possible to eliminate the conventional ironing process or color painting process by trowel work, etc., and shorten the construction period. At the same time, the cost can be reduced. Furthermore, when finishing the concrete surface to a rough state, it is also possible to use the decorative material for concrete as a repair material,
In this case, it is possible to reduce the number of steps for the conventional repair material.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below. The decorative material for concrete used in the present embodiment contains ordinary Portland cement, white cement, calcium carbonate, powdered serpentine, silica sand, titanium oxide, perlite, methyl cellulose, pigment (colored powder), and these are dried. Manufactured by mixing. These compounding ratios are generally in the following ranges. Ordinary Portland cement (about 1%), white cement (about 30-
50%), serpentine powder (20-30%), titanium oxide (1-2%), pigment (1-3%). Calcium carbonate, silica sand and pearlite as aggregates and methyl cellulose as an admixture are about 20%.

By using white cement as the main component of the decorative material for concrete, it is possible to easily develop the color shade due to the pigment. On the other hand, black cement is added in a small ratio to white cement. This is because the black cement facilitates the dispersion of the pigment and can prevent the color unevenness of the decorative material. Titanium oxide is required for surface enhancement and increased material compactness. The serpentine powder has a particle size of approximately 45 to 500 microns. The material and size of the contained aggregate are selected according to the roughness of the surface of the concrete skeleton. In order to make the final surface roughness of the concrete skeleton more accurate, it is preferable to use an aggregate having a small particle size of 0.3 mm or less. The pigment may be organic or inorganic and any pigment may be selected according to a desired color or shade.

Next, a method of constructing a concrete skeleton using a decorative material for concrete will be described. Construction method 1: This is an example in which the decorative material for concrete according to the present embodiment is used as both a repair material for a concrete skeleton and a color coating material. As shown in FIG. 1 (a), a repair material 22 is applied to repair irregularities on the surface of a concrete skeleton 21 that constitutes a wall surface or a floor surface. The repair material 22 generally contains cement as a main component, and the particle size and the thickness of the aggregate contained therein are selected according to the roughness of the surface of the concrete skeleton 21. If the surface roughness is small,
The aggregate may be selected to have a small particle size, and the thickness may be thin.
On the contrary, when the surface roughness is large, the aggregate having a large grain size is selected and the thick coating is performed several times.

Next, the decorative material 23 for concrete having the above-mentioned composition components is applied onto the repair material 22. When finishing the surface to a smooth surface, select a particle diameter of the aggregate contained in the decorative material 23 of about 0.3 mm or less,
The applied thickness is about 0.3-1 mm. This is comparable to conventional surface finish ironing. Further, the type and amount of the pigment contained in the decorative material 23 are selected according to the final color tone of the finished surface. In this way, construction method 1
Since the repair work and the color painting work can be simultaneously performed using one material, the construction period of the concrete building (wall surface or floor surface) can be shortened. Furthermore, since it is not necessary to color paint such as paint whose main component is an organic solvent, it is possible to apply makeup to concrete that is kind to the natural environment and suitable for human health.

Construction method 2: This is an example in which the decorative material for concrete according to the present embodiment is used both as a repair material for a concrete skeleton and as a color coating material. Some customers may want some roughness on the concrete surface for reasons of appearance or design. In this case, as shown in FIG. 1B, a decorative material 25 which also serves as a repair material is applied onto the concrete skeleton 24. The particle size of the aggregate contained in the decorative material 25 is slightly larger than the particle size required for the finished surface as shown in FIG. For example, it is about 0.3 to 2.0 mm. Thickness is 1 according to particle size
Apply about 0 to 30 mm.

Also in this case, by including a pigment in the decorative material 25, it is possible to form a concrete wall surface or floor surface having a desired color tone, and it is possible to carry out repair and repair without individually performing conventional ironing and color coating. Color painting can be done at the same time.

Although the preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the specific embodiments, and the scope of the gist of the present invention described in the claims is given. Within, various modifications and changes are possible. For example, the decorative material for concrete according to the present embodiment is not limited to the above composition ratio. Further, other substances may be contained as long as the essential characteristics of the present invention are not impaired.

[0015]

As described above, according to the present invention, the makeup of the concrete skeleton is performed using the concrete decorative material containing at least white cement, titanium oxide, powdered serpentine, and pigment. Since the concrete repair work and the color painting work can be performed at the same time, the construction work period can be shortened, and the construction cost can be reduced. Furthermore, since color coating containing an organic solvent as a main component is not required, it is possible to provide a building that is friendly to the natural environment and human body.
