Abstract

PURPOSE:To obtain a coloring material which can impart to the surface of civil engineering structures a color shade matching the natural color and has excellent workalibity, by using an aggregate which has been previously colored and fired as a main ingredient. CONSTITUTION:Siliceous sand is colored and fired to obtain a sand particle-like aggregate. New ceramic sand having a color like the natural color, formed by using said aggregate as a base and blending natual sand thereto, is used. A potent adhesive having desired ground treating power is mixed with the new ceramic sand. The mixture is sprayed on the outer surface of civil engineering structures such as mortared surfaces or concreted surfaces on the slope of a mountainside to color them.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is mainly applicable not only to sprayed surfaces and concrete surfaces on mountainside slopes, but also to dams on mountainside slopes, dam dams, stacked blocks, seawalls, wave-dissipating tetrabos, Aiming to harmonize various civil engineering construction surfaces and construction objects such as natural stones with nature without damaging the surrounding natural scenery is concerned with coloring substances and methods for coloring the surfaces of 6 civil engineering structures.

Mortar spraying, which is a very common slope protection work on mountainside slopes, is highly rated for its safety in terms of prevention of collapse, and has the largest construction surface m.

However, since the sprayed surface exhibits a white reflective surface after drying, it does not interfere with the surrounding natural scenery and causes disharmony with nature. It has been recognized that there are harmful effects such as causing changes in the fish ladder. For this purpose, methods such as coating the mortar spray surface with colored paint or spraying with Kawo Mortar A/f may be adopted, but these methods have advantages and disadvantages in terms of four colors, peeling, cost, etc. is the current situation. For example, in the case of coloring using a coating method, the coating is generally too glossy and the coating is thin, so unless an expensive coloring agent is used, it has the disadvantage of being prone to yellowing, embedding, and deterioration. In addition, in the case of Kawomo μ-tal spraying, the coloring agent mixed into the mortar is the most expensive for the edge threads, followed by black threads and brown, but among these, the coloring agent for the edge threads is When spraying after mixing with mortar, a large amount of coloring agent is required to color the entire amount of moiretal, and efflorescence occurs on the surface of the colored mortar, requiring a large amount of coloring agent. It was a relatively large loss. Here, the efflorescence phenomenon of mortar is a phenomenon in which the scum of the mortar oozes out to the surface, and as a result, the surface of the colored mortar becomes white. Therefore, by spraying the first layer of the ground-treated mountainside slope with normal mortar and spraying the second layer above it with colored mortar, material loss can be reduced. Not only was it difficult to completely prevent the efflorescence phenomenon, but it was also likely to cause peeling between both mortars.

The present invention solves the various problems associated with the coloring method of civil engineering structure replacement surfaces by using sand granular aggregate made by coloring and firing silica sand, which has the same effect as miniature ceramics and is semi-permanent. Focusing on the fact that it is made from materials that are not imported, we use the colored fired sand granular aggregate as the base, and add natural sand to it to create a new ceramic sand color that is close to natural. In addition to being used as a coloring substance on the surface of structures, a strong adhesive with the required surface treatment ability is mixed with the two-needle ceramic sand, and this can be applied to the 7-μm sprayed surface of a mountain slope or a concrete surface. In addition, we also provide a coloring method for spraying the outer surfaces of mountainside slope dams, dam dams, stacked blocks, etc., with the aim of achieving harmony with the natural environment for various civil engineering structures. .

First, the mixing ratio of the coloring substance and the adhesive according to the present invention is as follows in the case of Example 1, which produces a green color such as dark green.

Example 1 Mixing ratio of new ceramic sandbar (2) to (2) and adhesives (E) and (F) (total 10 parts) that produce a greenish color.Thus, the color and aggregate as shown in Example 1 were prepared. After mixing 5 parts (27 & y) of colored calcined aggregates (a), (o), (c) with 5 parts (27 & y) of particle size and 5 parts (27#)'t- of silica sand, acrylic was developed mainly for mortar sprayed face metal. An adhesive that is a modified emulsion of acid ester copolymerization that also has the ability to treat the surface of mortar with dust, moisture, etc. Specifically, "Movinyl Modified Product" (product name) manufactured by Hoechst Gosei Co., Ltd. was added to 3.3 parts as the main adhesive agent (E), and [Tyrose f (1000 [
6.36 parts (18&y) of an adhesive made by adding 0.05 parts of IJ (trade name) as a thickener (to) is mixed and mixed with a mixer, and this is prepared on a mountainside with a pre-surface treatment. The sprayed surface of the slope will be treated. Then,
The sprayed surface exhibits the dark green color of the colored fired aggregate itself, and a relatively rough surface is formed.

At this time, if you want to colorize the old mortar-sprayed surface of a mountainside slope that has been installed for more than a year, you must first remove all moss and deposits, or remove the old mortar-sprayed surface. If the surface has changed significantly over the years, the surface should be treated first, then the surface to which it was sprayed should be treated again, and the surface to which it was sprayed should be colored.

Next, as Example 2, we will show the blending ratio of the coloring substance to produce a brownish color such as Sakurajima lava color, and as English can example 6, we will show the blending ratio to produce a Fuji lava color hue. , respectively, are as follows.

Example 2: Total amount of brown ceramic sand color (e.g., Sakurajima lava color).Example 3: Mixing ratio of Sunu Ceramic Sand, which produces a black color (e.g., Fuji lava color) (9 parts in total). After mixing colored calcined aggregate and silica sand etc. in the proportions shown in Example 2.6 above, the same adhesive (main ingredient and thickener) as in Example 1 was added (4 parts of gold in Example 2). In the case of Example 6, about 6 parts of each were added and stirred, and the base was treated and sprayed on the slope of Kuyama. In the case of Example 2, a brown color similar to Sakurajima lava was obtained. Series of color alloys and Example 3
In this case, a rough surface is formed that exhibits a blackish color similar to that of Fuji lava.

In the above case, is the mortar sprayed surface mainly on the mountainside slope? Although the case of coloring to green, brown, and black hues has been described, the gist of the present invention will not be changed in any way even if the coloring process is performed to a hue other than the above depending on the surrounding natural situation. -x, t, in the above case, mainly 7 μ
Although we have explained the case where the entire barrel sprayed surface is colored, the same applies to the case where the concrete surface of the hillside slope, the surface of various civil engineering structures such as dams, dams, stacked blocks, etc. are colored to match the surrounding nature. be.

In order to color the surface of a civil engineering structure as described above, the present invention provides a material for coloring the surface of a civil engineering structure that uses colored and fired aggregate as its main raw material, and a material that is colored in advance. A coloring treatment for the surface of civil engineering structures, which is made by mixing adhesive with new ceramic sand, which is made by mixing natural sand with a base of calcined large and small aggregates, and spraying this on the surface of civil engineering structures. As a result of this law, the surface of this type of civil engineering structure can be made to have a color that matches nature.

At that time, since colored and fired aggregate is used as the main raw material, a rough surface with no gloss and no deterioration is created, and a shadow is created by the formation of the rough surface, creating a state that is close to natural. is formed and is effective. Moreover, it has excellent workability, can be constructed in a relatively short period of time, and has various effects such as excellent economic efficiency.
