料として使用することが考えられ、試みられている。2. Description of the Related Art Conventionally, industrial waste containing metal is subjected to high heat treatment in a melting furnace, and the resulting slag is passed through a large amount of water to form a granular powder, which is then used. An attempt was made to do so. Since the powder and granules obtained here have a diameter of several tenths of a millimeter to a few millimeters and are similar to rocks and sands, it can be considered to be used, for example, as a basic material for road construction or a basic material for various civil engineering. Being tried.

業廃棄物スラグは、粒子相互の結着力が弱いため、一定
の形状をもった成形物として利用することはできない。By the way, industrial waste slag is characterized by containing many metal components and having a larger specific gravity than sand grains and cement. On the other hand, this particulate industrial waste slag cannot be used as a molded product having a certain shape because the binding force between the particles is weak.

い。On the other hand, the amount of industrial waste tends to increase remarkably in recent years, and the method of utilizing powdery particles after high heat treatment has not been established yet. In addition, since industrial waste contains various metal components and certain harmful components, if these substances are easily used as civil engineering materials, the harmful components contained may infiltrate groundwater and pose a risk to urban life. I can't wipe it.
【０００５】そこで本発明の目的は、大量に得られる産
業廃棄物スラグを、環境に影響を与えない土木建築基礎
成形材として再利用させる点にある。Therefore, an object of the present invention is to reuse a large amount of industrial waste slag as a base material for civil engineering and construction which does not affect the environment.

る。In order to achieve the above object and achieve the object, in the present invention, after slag obtained from a melting furnace for industrial waste is poured into a mold material having a predetermined shape and cooled. The mold material is removed, and a liquid resin coating material is applied to the surface of the slag molding. Instead of the resin coating, a resin sheet is wound around the surface of the slag molded body after cooling, or the surface is covered with a resin panel material.

As a result of the surface resin resisting external forces of bending and tension in a rebar-like action, it exerts extremely high structural properties. The solid slag whose surface is coated with a resin does not deform even by an external force that can be predicted in advance, and can maintain the initial shape even if the interparticle bond weakens and it collapses like a sand grain.

応じて被覆材を設計すれば良いからである。A substance having a composite of metal and other components, such as industrial waste slag, does not need to be passed through water to be reduced to a granular material. This is because it is possible to obtain a molded product that can be stably used by cooling the mold as it is in the molten state and applying a resin coating material on the surface. The coating material may be any of liquid resin, spray resin, resin film material, and resin panel material. This is because the coating material may be designed according to the required strength of the molded product to be applied.

It can be widely used as a basic molded article for general building civil engineering such as brick substitutes, tetrapots, and various panel materials. In addition, since the surface is coated with resin, there is no erosion due to raindrops, and there is no risk of harmful components leaking to neighboring soil, groundwater, rivers, or the ocean.

FIG. 1 is a block diagram illustrating a method for reusing industrial waste slag according to the present invention, and slag as a raw material is obtained from a melting furnace (combustion furnace) 1 for industrial waste.

The term "industrial waste" includes not only metal-containing products such as old tires and injection needles, office-related waste such as computer paper, but also household waste.

Then, it is solidified by pouring it into the container and leaving it or rapidly cooling it (4). Since the mold 3 can be designed appropriately according to the purpose of use, its shape is not particularly limited. The shape can be freely designed, such as a rectangular block, a pillar, a cylinder, a sphere, a tile panel shape, a Tetrapot (registered trademark) shape (or a part shape thereof), and an embankment slope protection block shape of an ocean river.

Solid slag 5 is obtained. Since the solid slag 5 is still in a brittle state, a liquid resin 6 is applied to the surface thereof and the liquid resin 6 is solidified to obtain a product block (panel) 7. The resin used in this case may be of any type such as epoxy resin and fiber composite resin (FRP). It is appropriately selected according to the durability, strength and cost required for the final product block 7. The applied thickness is also the same.

曲げ応力など、構造特性は殆ど低下しない。Since the cooling particles of the industrial waste slag have a weak binding force between the particles, it has not been possible to stably use the particles as a molded product in the past, but as described above, the surface of the molded product is elastic. The shape does not collapse when covered with, and even if cracks occur inside the provisional stress, tensile stress,
Structural properties such as bending stress are hardly deteriorated.

確認している。Regarding the structural characteristics when the surface of the molded product is coated with a resin material, the present applicant has already made various proposals regarding the concrete structure. Examples include secondary concrete products, utility poles, and reinforcement of concrete structures.
As a result of subsequent experiments, regardless of the type and properties of the internal filling,
It has been confirmed that by coating the surface with resin, it is possible to obtain excellent structural characteristics that exceed the reinforcing characteristics when reinforcing bars are used.

In this product block 7, the surface resin (6) exerts stress against bending and tension, so that the molded shape is not destroyed. As a result, it can be applied to, for example, frame blocks for park flower beds, curbs on roads, paved blocks for promenades, and the like. Further, since the stress characteristic more than that of the case where the reinforcing bar is arranged inside can be obtained, as long as the weight is not more than the predetermined weight, it can be used for the supporting portion of the heavy object.

も良い。The slag block (7) exhibits stronger strength by coating the surface with a resin sheet and by coating a resin panel. By using, for example, a fiber composite resin (FRP; CC-FRP) as the resin material, the strength is further increased and the heat resistance is also increased. As a result, it can be applied to a wall panel or a tetra pot that requires higher structural strength. When using a resin panel, even if the molten slag is not cooled by a mold (molding frame), the heat insulation base is applied to the inner wall surface of the resin panel molded into a predetermined shape,
The final product may be obtained directly by pouring the molten slag into the internal space.

In this case, the refractory material may be a single material surface coating, a single sheet (or panel) surface coating, or it may be applied (or coated) on a heat insulating material. For example, a metal sheet may be attached onto a ceramic or resin-based heat insulating material.
