Even in concrete buildings and various wall surfaces, it is no longer possible to simply decorate with color or use tiles, etc. as in the past. It is desired to provide a wall material and its finishing material that is not decorated with a mosaic pattern, but is translucent, which allows for daylight to be let in, and which can be decorated with various types of light. This invention was made in view of the above circumstances, and its purpose is to provide a cement composition for producing translucent cement products, which is completely different from the decoration of conventional cement products. Our goal is to provide the following.

Various types are used depending on the desired properties of the product. Further, as the ultra-lightweight fine aggregate, one having a specific gravity of 0.9 or less, such as Neolite (trade name; manufactured by Niijima Bussan Co., Ltd.), is preferably used. Here, as this ultra-lightweight fine aggregate, one having a particle size of 5 to 0.3 mm is preferable in order to ensure sufficient strength of the obtained cement product and to ensure translucency as described below.

(Product name: Mitsui Toatsu Co., Ltd.) is used. On the other hand, as the epoxy resin, one consisting of a base resin and a curing agent is preferably used, such as FLEP-50 (trade name; manufactured by Toray Thiokol Co., Ltd.). Of course, the composition of the present invention may be prepared by blending only one of these polyester resins and epoxy resins.

When using both epoxy resin and polyester resin, the volumetric ratio of the total amount of both epoxy resin and polyester resin to the amount of ultra-light fine aggregate should be determined in order to ensure sufficient strength and translucency of the resulting cement product molded body. The ratio is preferably 1:1 to 1:1.5, more preferably 1:1.21. Here, the reason why the ultra-lightweight fine aggregate is about 70 to 90 parts by weight is because the ratio with the resin is 1:1 to 1:1.5, as described above.
This was decided based on the need to make the resin concrete concrete in an amount exceeding 90 parts by weight, as the translucency of the resin concrete would be impaired. This is because it no longer exhibits sufficient strength.

A high-performance water reducing agent), a fluidizing agent, an admixture, etc. are appropriately blended, and various fibers and pigments are also blended. Here, the fibers used include glass fibers, vinylon fibers, aramid fibers, carbon fibers, and various ceramic fibers, and the addition of these fibers can increase the strength of the resulting cement product. In addition, the amount of such fibers added is about 1 to 4% by volume of the entire cement composition, and if it is less than 1% by volume, the reinforcing effect will not be exhibited, and if it exceeds 4% by volume, the reinforcing effect will not be exhibited. This is not preferable because the effect remains almost the same and the cost increases. Furthermore, it is preferable to add a pigment to color the cement product, since the decorative properties due to the transmission of light will be further enhanced.
