Embodiments for Carrying Out the Invention

[0020] Hereinafter, embodiments of the present invention will be illustrated and described with reference to the drawings.

[0021] As shown in FIGS. 1 to 2, in one embodiment of the present invention, the cement composition finished structure 1 is a cement composition finished structure 1 made of the cement composition 1b, and has a finished surface 1a on which a hologram is formed in the material itself of the cement composition 1b. According to the above configuration, the material itself of the cement composition 1b can be imparted with design properties by the hologram on the finished surface 1a.

[0022] The cement composition 1b is not particularly limited, and examples thereof include cement paste, mortar, concrete, and the like. The cement paste is composed of only a binder containing a cement-based hardening material and water. The binder may be configured to contain an admixture in addition to the cement-based hardening material. The mortar is composed of a binder, water, and an aggregate, and the aggregate is composed of only fine aggregate. The mortar may be configured to contain reinforcing fibers such as steel fibers and resin fibers in addition to the binder, water, and aggregate. The concrete is composed of a binder, water, and an aggregate, and the aggregate is composed of fine aggregate and coarse aggregate.

[0023] The finished surface 1a has a surface structure in which a hologram is formed on the cement paste itself. According to the above configuration, the hologram on the finished surface 1a can be easily formed by transfer. The above surface structure may be formed by using a cement paste as the cement composition 1b, or by using mortar or concrete as the cement composition 1b and causing the cement paste to float on the surface by a vibrator.

[0024] The water-binder ratio (W / B) of the cement composition 1b is not particularly limited, but is, for example, 15% or less. According to the above configuration, the hologram on the finished surface 1a can be formed more easily by transfer.

[0025] The cement composition finished structure 1 may be provided on a site-constructed object. According to the above configuration, a site-constructed object can be realized in which the material of the cement composition 1b itself can be given a design property on the finished surface 1a. A site-constructed object is an object produced by construction at the site where a building having the finished surface 1a constituted by the site-constructed object is constructed, and constitutes, for example, a floor, a wall, a ceiling, a beam, etc.

[0026] The cement composition finished structure 1 may be provided on a product manufactured in a production facility. According to the above configuration, a product manufactured in a production facility can be realized in which the material of the cement composition 1b itself can be given a design property on the finished surface 1a. A product manufactured in a production facility is an object manufactured in a production facility such as a factory, and is transported to the site where a building having the finished surface 1a constituted by the product manufactured in the production facility is constructed and used for construction, and constitutes, for example, a floor, a wall, a ceiling, a beam, etc.

[0027] As shown in FIGS. 1 to 2, in the method for manufacturing a cement composition finished structure according to the present embodiment, the method for manufacturing a cement composition finished structure for manufacturing the cement composition finished structure 1 is a method for manufacturing a cement composition finished structure 1 by placing the cement composition 1b in a formwork 2 having a hologram-processed formwork surface 3 as the placement surface of the cement composition 1b, thereby manufacturing a cement composition finished structure 1 having a finished surface 1a with a hologram formed on the material itself of the cement composition 1b. According to the above configuration, since the hologram processing transfer surface 4 obtained by transferring the hologram of the hologram processing formwork surface 3 can be formed on the finished surface 1a, the material itself of the cement composition 1b on the finished surface 1a can be imparted with design properties by the hologram.

[0028] When manufacturing a production facility product having a cement composition finished structure 1, the placement of the cement composition 1b can be performed, for example, by pouring the cement composition 1b into the recess of a formwork 2 having a hologram processing formwork surface 3 on the bottom surface of a recess that opens upward as shown in FIG. 1. Then, after the cement composition 1b has hardened, by taking out the cement composition 1b from the formwork 2 as shown in FIG. 2, a production facility product having a cement composition finished structure 1 can be obtained. The formwork 2 may be formed by attaching a hologram sheet (a sheet having a hologram-processed formwork surface 3 on its surface), such as a resin sheet, to a formwork base material. In this case, from the viewpoint of facilitating the formation of the hologram processing formwork surface 3, the hologram processing formwork surface 3 is preferably a plane or a developable surface (a curved surface having a shape that can be developed into a plane without stretching).

[0029] When manufacturing an on-site construction body having a cement composition finished structure 1, it is based on the conventional method of building a formwork, arranging steel bars, and then pouring concrete in a concrete construction, and a hologram sheet may be attached to the inside of the formwork.

[0030] The hologram processing mold surface 3 is composed of fine irregularities having a periodic structure. According to the above configuration, fine irregularities obtained by transferring the fine irregularities of the hologram processing mold surface 3 can be formed on the hologram processing transfer surface 4, and a hologram (relief type hologram) by interference fringes can be formed by the fine irregularities of the hologram processing transfer surface 4. Note that the contour shape of the fine irregularities of the hologram processing transfer surface 4 is substantially the same as the contour shape of the fine irregularities of the hologram processing mold surface 3. The periodic structure of the fine irregularities is not particularly limited, and examples thereof include a stripe pattern (a periodic structure in which irregularities are repeated in one direction), a lattice pattern (a periodic structure in which irregularities are repeated in two directions), and the like.

[0031] The height H of the fine irregularities is not particularly limited, and for example, it is larger than 0.05 μm and 100.00 μm or less, preferably 10.00 μm or less, and more preferably 1.00 μm or less. According to the above configuration, the hologram of the finished surface 1a can be easily formed by transfer from the hologram processing mold surface 3.

[0032] The pitch P of the fine irregularities is not particularly limited, and for example, it is larger than 0.10 μm and 100.00 μm or less, preferably 50.00 μm or less, and more preferably 10.00 μm or less. According to the above configuration, the hologram of the finished surface 1a can be more easily formed by transfer from the hologram processing mold surface 3.

[0033] The hologram processing mold surface 3 may be formed by embossing (pressing). According to the above configuration, the hologram processing mold surface 3 can be easily formed.

[0034] The hologram processing mold surface 3 may be configured such that no paint is applied. According to the above configuration, it is possible to easily and accurately form the hologram processing mold surface 3 on which the hologram is processed.

[0035] The hologram processing mold surface 3 may be made of resin. According to the above configuration, it is possible to easily and accurately form the hologram processing mold surface 3 on which the hologram is processed.

[0036] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and the above-described embodiments can be variously modified without departing from the gist of the present invention.

Example

[0037] As an example of the present invention, a finished structure of a cement composition was manufactured. An example of the mold used is shown in Fig. 3. Also, the manufactured finished structure of the cement composition is shown in Fig. 4. The hologram processing mold surface was formed by the surface of a resin sheet on which a hologram was processed. As the cement composition, mortar "Slimcrete (trademark)" was used. On the hologram processing transfer surface of the manufactured finished structure of the cement composition, a hologram shining in rainbow colors was formed without using any paint.

[0038] When observed with a scanning electron microscope, in the example shown in Fig. 5, the fine irregularities on the hologram processing mold surface have a striped periodic structure (see also Fig. 7), and the pitch of the fine irregularities is 1.08 μm or more and 1.20 μm or less. In the example shown in Fig. 6, the pitch of the fine irregularities on the hologram processing transfer surface was 1.05 μm or more and 1.18 μm or less. In the examples shown in Figs. 8 to 9, the hologram processing transfer surface has a lattice-like periodic structure, the pitch of the fine irregularities is 0.714 μm or more and 1.05 μm or less, and the height of the fine irregularities is 0.089 μm or more and 0.148 μm or less.
