Abstract

PROBLEM TO BE SOLVED: To remove stains, moss or the like from surfaces of a concrete wall, a block wall, a brick wall or the like, to execute construction in a wet state, to apply finishing on a cured surface, to simplify the construction for a short construction period, to reduce industrial wastes, and to attain natural appearance finishing.SOLUTION: The appearance paving material contains a lightweight aggregate, hydrated lime, a mortar adhesion promoting agent and a coloring agent. The mortar adhesion promoting agent (powder and liquid) is strong in adhesion between the lightweight aggregate and the hydrated lime and low in water absorption and water permeability. The appearance paving material has a mixing ratio of 1-10% pts.wt. of the mortar adhesion promoting agent and 1-5% pts.wt. of the coloring agent relative to 100% pts.wt. of the aggregate (lightweight aggregate+hydrated lime).

Description

  The present invention relates to a finishing surface construction method on the surface of concrete, block, brick wall, etc., and finishes the surface of concrete, block, brick wall, etc., finishes the solidified part, and simplifies the construction period. It is related with the construction method which enabled the shortening of an exterior, the recycling of an outer wall, and the natural appearance pavement.

  The surface of the current concrete, blocks, brick walls, etc. has deteriorated due to discoloration, peeling, etc., and most of them are not repaired. . In addition, scrapped concrete shells such as concrete, blocks, and bricks have a problem of industrial waste disposal.

  Construction methods such as concrete, blocks and brick walls are used around the current houses and facilities. Concrete, blocks, brick walls, etc. have deteriorated due to surface discoloration, peeling, etc., and the construction is complicated and has not been developed or left for economic reasons.

  The problem to be solved by the present invention is a surface finishing method that fulfills the required external appearance protection function of concrete, blocks, brick walls, etc., maintaining its continuity and suppressing industrial waste, etc. Is to provide technology.

  The present invention addresses the above-described problems, and its purpose is to provide a construction method that can shorten the construction period and simplify the construction method, suppress industrial waste, and contribute to the beautification of the appearance. is there.

Means to solve the problem

A mortar adhesion enhancer (ethylene vinyl acetate copolymer) (powder / aqueous solution) is used. The use of the mortar adhesion enhancer has an effect of improving the adhesion of the aggregate and the adhesion to the lower layer, and having low water absorption and water permeability resistance.
As for the usage-amount of a mortar adhesion enhancer, a mortar adhesion enhancer (1-10) weight part is desirable with respect to 100 weight part of aggregates (lightweight aggregate + slaked lime). If the amount is too small, the intended effect cannot be obtained.

A colorant (silicon acrylic resin) is used.
The use of the colorant allows the color to be freely selected according to the application and environment, and further has a strong characteristic against dirt, salt damage, ultraviolet rays, acid rain, and exhaust gas.
As for the usage-amount of a coloring agent, a coloring agent (1-5) weight part is desirable with respect to 100 weight part of aggregates (lightweight aggregate + slaked lime).
Increase / decrease depending on color shade.

The invention's effect

  To fulfill the function as a simple pavement, It can be easily constructed manually. 2. Naturalness in harmony with the surrounding environment. 3. By mixing lightweight aggregate, slaked lime, mortar adhesion enhancer and colorant, the color can be expressed to your liking. 4). Expected to suppress industrial waste. The effect of fulfilling these functions can be expected.

  The simple pavement material according to the present invention includes a lightweight aggregate, slaked lime, a mortar adhesion enhancing material (powder / aqueous solution), and a colorant.

  The physical properties of the cured material having the above composition are shown in FIG.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments embodying the present invention will be described below with reference to the drawings. FIG. 2 is a process diagram for explaining an operation process according to an embodiment of the present invention.

  The construction method of the embodiment is roughly divided into three steps: (1) cleaning and washing process of finished surface, (2) step of moistening the finished surface, and (3) surface finishing step. It consists of the structure which formed surface parts (solidification part), such as a brick wall.

  The cleaning / cleaning process for dirt on the finished surface is a process for cleaning / cleaning to remove dirt, moss and the like attached to the surface.

  The step of moistening the finished surface is a step of improving the adhesion between the paving material and the finished surface.

  The step of finishing the surface is a step of finishing the pavement material with a trowel or the like.

  From the above results, in the case of the present working example, it was confirmed that the construction method was simplified, the construction period was shortened, and surface finishing was possible compared to the conventional construction method.

  The present invention is not limited to the above-described embodiments, and includes configurations that can be modified within a range that does not change the gist of the present invention. However, if necessary, it can also be summarized as a surface finishing construction method for other retaining walls.

  As described above, according to the construction method of the present invention, the surfaces of concrete, blocks, brick walls, etc. around houses and facilities are cleaned, washed and moistened, and the pavement is directly applied, and the surface finish and solidification・ Because it is cured, it can be applied to concrete, block, and brick wall as it is, so the construction period can be shortened.
