中に散布するようにしている。(Prior Art) As is well known, various building materials such as concrete and mortar are mainly formed by bonding sand-like particles for building materials using a binder such as cement. In this case, in order to increase the mechanical strength of the building material, conventionally, building material granules and reinforcing fibers are mixed and bonded using a binder. The use of glass fibers as reinforcing fibers has been practiced for a long time. For example, when forming G-e-R- (glass fiber reinforced concrete), long glass fibers are placed in a mortar spray gun. While cutting the powder, it is dispersed into the building material granules.
ところで、近時では、補強用繊維として、炭素。By the way, recently carbon has been used as a reinforcing fiber.

It is mixed into the mortar.
しかしながら、上記のような従来の建材の形成手段では
、補強用繊維を建材中に均一に分散させることが非常に
むずかしく、ファイバーボールができたり、不均一な分
散のために形成された建材が機械的強度の点で十分な信
頼性を得ることができない等の問題を存している。However, with the conventional means for forming building materials as described above, it is very difficult to uniformly disperse reinforcing fibers in the building materials, and fiber balls may be formed, or the formed building materials may be damaged due to uneven dispersion. However, there are problems such as not being able to obtain sufficient reliability in terms of physical strength.

していくものである。Furthermore, currently, as a method for uniformly dispersing reinforcing fibers in building materials, mixing granules for building materials and reinforcing fibers is carried out using an omni-mixer. This omni-mixer does not have stirring blades and performs diffusion and mixing using flexible rubber balls mounted on a oscillating plate.
The mixture is mixed by slowly scattering it in random directions.
ところが、上記のようにオムニミキサーを用いた方法で
も、髪の毛よりも細い補強用繊維を建材中に均一に分散

る。However, even with the method using an omnimixer as described above, it is still impossible to mix reinforcing fibers that are thinner than a human hair so that they are uniformly dispersed in the building material.

になるという問題を有している。(Problems to be Solved by the Invention) As described above, with the conventional reinforcing fiber mixing means, it is difficult to uniformly disperse reinforcing fibers into building materials.
The problem is that the resulting building material is unreliable in terms of mechanical strength.
そこで、この発明は上記事情を考慮してなされたもので

Furthermore, it is an object of the present invention to provide an extremely good method for dispersing reinforcing fibers mixed into building materials, which can form building materials having sufficient mechanical strength and reliability.

、高速撹拌されるので、補強用繊維を建材中に均一に分
散させることができるようになるものである。(Function) According to the above method, the reinforcing fibers are attached to the building material granules due to moisture on the surface of the building material granules and are stirred at high speed, so that the reinforcing fibers are incorporated into the building material. This enables uniform dispersion.

強用繊維を加え、例えば高速混合機によって撹拌する。(Example) Hereinafter, an example of the present invention will be described in detail. First, an appropriate amount of water is added in advance to sand as granules for building materials, and the mixture is thoroughly mixed to wet the surface of the sand. Next, reinforcing fibers are added to this sand and agitated, for example with a high speed mixer.

粘着して、補強用繊維が砂中に均一に分散されるように
なる。Then, due to the rotating centrifugal force of the pan containing the sand and reinforcing fibers, the material pressed against the pan wall changes direction and is scattered by the scraper and the agitator rotating at high speed. At this time, the water on the sand surface and the water adhering to the fiber surface stick together, and the reinforcing fibers become uniformly dispersed in the sand.
この場合、砂に加える水は、通常の水に代えて、例えば

ものである。In this case, the water added to the sand may be replaced with ordinary water, for example, a sticky liquid such as polyvinyl alcohol or methyl cellulose. The amount of water on the surface of the sand is in the range of 1 to 10% of the weight of the sand, and may be increased or decreased within the above range depending on the properties of the fibers, their thickness, amount of mixture, etc.
