する。この状態を図４に示す。The washing method comprises the following steps. A foundation concrete layer 2 is provided on a crusher run 1. Crusher run 1 and the foundation concrete layer are called foundation. A mortar layer 3 is provided thereon, and a decorative aggregate 4
Is applied. This state is shown in FIG. Next, a hardening retardant is sprayed on the pre-grout mortar 5 and a cured plastic sheet 6 is put thereon. This state is shown in FIG. Next is 2 hours in summer
It is left for 3 hours, and for 4 to 6 hours in winter, and the part other than the surface of the pre-grout mortar 5 is cured. The surface of layer 5 does not cure due to the presence of a cure retarder. The cured sheet is removed, and the mortar component that is not hardened on the mortar 5 is washed out with water to form decorative concrete. This state is shown in FIG.

くということが時々起った、化粧骨材が自重でモルタル
組成物の中に沈んでいくことは、表面状態を不安定にさ
せ、均一な製品を作ることが困難になった。(A) As shown in FIG. 5, when the decorative aggregate is placed on the mortar composition, the weight of the decorative aggregate itself is still under the effect of the stone of 0.2 to 15 mm contained in the mortar composition 14. It sometimes happened that the cosmetic aggregate sinked into the mortar composition, and the cosmetic aggregate sinking into the mortar composition by its own weight made the surface state unstable and uniform. It has become difficult to make products.

くなる。(C) The decorative aggregate must be placed on the mortar composition after it has been wetted without fail. Since the surface layer of the mortar composition is dry, the dried cosmetic aggregate is placed on the mortar composition and pressed in, and both of the contact surfaces between the dry cosmetic aggregate and the surface layer of the mortar composition are dried. There is no affinity, and as a result, the decorative aggregate does not completely adapt to the mortar, and the mortar rises. Also, if the decorative aggregate is too wet, the mortar around the decorative aggregate is too wet and soft, the stones sink too much, and the mortar tends to be efflorescent, which makes the mortar unattractive.

タルに固着する。In the present invention, since a net is used, the decorative aggregate does not sink into the mortar composition by its own weight. Also, when the decorative aggregate is pushed into the mortar composition, the mortar composition does not rise abnormally. In the method of the present invention, the decorative aggregate can be used as it is dry. When the cosmetic aggregate was pushed in, even if the surface layer of the cosmetic aggregate was dry, the mortar composition was cut off by the net, and the mortar composition containing water came up from the inside, and the aggregate contained water. Upon contact with the internal mortar composition, the aggregate is completely fixed to the mortar.

くなる。The network 4 mm 2 -100 mm 2, preferably has an opening of 8 mm 2 -40 mm 2. Any net material can be used as long as it is alkali-resistant.
Usually, a net formed of vinylon, glass fiber, polyethylene or the like is preferable. If the size of the opening is smaller than 4 mm 2 , the mesh blocks the mortar composition from rising. If the size of the opening is larger than 100 mm 2, the result is the same as when no mesh is used, and the use of the mesh is meaningless.
【００２５】本発明では、そのモルタル組成物は、石を
