Here, the solidified material which is a part of the base portion 10 is to harden the masato and quarry waste, and it is preferable to use those having a low iron content in steelmaking sludge and dust without using cement-based solidified material.

When the base portion 10 is in surface contact with the base portion 10 of the other ocher sidewalk block 2 adjacent to the entire base surface of the base portion 10, since the initial installation is not easy, other adjacent loess The protrusions 12 protrude from the base layer portion 10 side of each ocher sidewalk block 2 so as to be spaced apart from the base layer portion 10 of the sidewalk block 2.

The protrusion 12 is formed in a convex rounded shape to the outside, and is formed long in the vertical direction.

The ocher sidewalk block 2 may be formed of ocher powder as a whole, such as a conventional zodiacal brick, but since the ocher powder is generally more expensive than masato, etc., the base portion 10 which is not in direct contact with the human body 10. ) Contains Masato, which is a lower cost material than ocher powder, and the ocher powder is preferably included only in the surface layer portion 20.

The ocher sidewalk block (2) is preferably provided in the sidewalk block or apartment complex of the city, it is of course possible to be provided on the floor of the jjimjilbang.

The surface layer 20 may be made of only ocher powder and solidified material. However, when a part of the fine ocher powder adheres to the vibration press molding machine of the conventional press block, the ocher press block 2 is removed from the mold of the vibration press molding machine. When separated, the appearance is not good and the surface becomes uneven, it is preferable that dolomite mill coat is mixed to minimize the phenomenon that the ocher powder adheres to the mold of the vibrating pressure molding machine.

The surface layer 20 is an ocher powder having a mesh of 24 to 60, a dolomite milk coat having a mesh of 12 to 24 is used, and the dolomite wheat coat has a larger particle size than the mesh, so that the ocher powder is used in a mold of a vibrating press. Minimize sticking.

The surface layer 20 may be sand or the like larger than the ocher powder may be used in place of the dolomite mill coat, but in the case of the dolomite mill coat, since it may function to neutralize acid rain, it is most preferable to mix the dolomite mill coat. Do.

On the other hand, the solidified material which is part of the surface layer portion 20 is to harden the ocher powder, dolomite wheat coat, it is preferable to use those having a low iron content in the steel-making sludge and dust without using cement-based solidified material.

The surface layer 20 is preferably a mixture of the ocher powder and the milk coat in a 1: 1 ratio by weight so that the surface layer 20, in particular, ocher powder is easily separated from the mold of the vibrating pressure molding machine to be described later.

The surface layer 20 is most preferably composed of the ocher powder, the wheat coat and the solidified weight ratio of 35 to 45% loess powder, 35 to 45% dolomite wheat coat and 15 to 20% solidified material.

Figure 2 is a plan view of one embodiment of the ocher sidewalk block according to the present invention, Figure 3 is a state diagram used in the embodiment of the ocher sidewalk block in accordance with the present invention.

The surface layer portion 20 is formed with continuous inclined portions 22, 24, 26, 28 along the edge.

When the plurality of ocher sidewalk blocks 2 are arranged before, after, left and right, the base layer 10 is arranged to be in close contact with each other, and the surface layer 20, in particular, the inclined portions 22, 24, 26, 28 (28). ) Are spaced apart from each other to minimize contact between the surface layers 20.

When the ocher sidewalk block 2 is disposed adjacent to each other, the edge of the surface layer portion 20 is inclined so that the base layer portion 10 is easily adhered without scratching or damaging the surface layer portion 20.

The ocher sidewalk block (2) is to minimize the friction between each other than when the edge of the surface layer portion 20 is formed orthogonal to prevent damage to the surface layer portion 20 that may occur during initial placement and to have a good appearance do.

The ocher sidewalk block (2) does not chamfer the edge, and forms a slope, so there is no separate jamming jaw when combined continuously and it is convenient to walk.

Figure 4 is a flow chart of one embodiment of a method for manufacturing an ocher footpath block according to the present invention.

First, in order to form the base portion 10, Masato, quarry waste, and solid ash are put into the first blender at 25% by weight of Masato 25-35%, sedimentary waste soil 50-60%, and 15-20% solid waste. A base portion mixing step of adding and mixing is performed. (S1)

Subsequently, a first vibration pressure molding step is performed in which a mixture of Masato and the like mixed in the base part mixing step is put into a mold of a vibration pressure molding machine to perform primary vibration pressure molding. (S2)

On the other hand, apart from the molding of the base layer 10, 35 to 45% of the ocher powder, 35 to 45% of the dolomite wheat coat, and 15 to 20% of the solidified material are added to the secondary blender and mixed with water. The surface layer mixing step is performed.

A secondary vibration pressure forming step of supplying a mixture such as ocher powder mixed in the surface layer part mixing step to one surface of the first vibration pressure molded base part is performed by secondary vibration pressure forming. (S4)

 Subsequently, the ocher sidewalk block vibrated under pressure in the second vibratory pressure forming step is separated from the mold of the vibrating pressure molding machine.

At this time, the ocher sidewalk block (2) is because the surface layer 20 includes a dolomite mill coat, it is more easily separated from the mold of the vibratory family molding machine than when only made of fine ocher powder, the ocher powder is in the mold of the vibration press molding machine It will not stick.

Thereafter, a steam curing step of steam curing the ocher sidewalk block separated from the mold of the vibration press molding machine is performed.

Here, the steam curing step is stored in a steam curing chamber at 60 to 100 ℃ for a predetermined time, for example, 30 minutes.

Then, the natural curing step of natural curing the ocher sidewalk block that has completed the steam curing step is carried out. (S6) (S7)

The natural curing step is naturally cured in a separate curing room for a predetermined time, for example, 12 hours. (S6) Then, the ocher sidewalk block naturally cured in the curing room is loaded with a machine, for example, in a yard. Natural cure for 10 days. (S7)

Thereafter, the ocher sidewalk block is shipped outside (S8).

Table 1 shows the compressive and force strengths and absorbances of various embodiments of ocher walkway blocks.

<Table 1>

division Example 1 Example 2 Example 3 Compressive strength (kgf / ㎠) 242 235 210 Flexural strength (N / mm2) 6.4 6.3 5.8 Absorption rate (%) 6.5 7.1 7.5

In Example 1, the mixture was mixed in a primary mixer at 28% by weight of Masato 28%, Quarry Waste 56%, and 16% solids, and a high-strength mixed material was added to the solidified material and 1% of the solids were mixed. This is the case where the mixture was mixed in the secondary mixer with 41% of ocher powder, 41% of dolomite milk coat and 18% of solidified fire, and the high-strength mixed material was added to the surface layer by adding 1% and water to the solidified material.

In Example 2, the mixture was mixed in a primary mixer at 28% by weight of Masato 28%, Quarry Waste 56%, and 16% solidified material, and the high-strength mixed material was added to the solidified material and 1% of the solidified material was produced. This is the case where the mixture was mixed in the secondary mixer with 58% of ocher powder, 24% of dolomite milk coat and 18% of solidified fire, and the high-strength mixed material was added to the surface layer by adding 1% of water and water.

In Example 3, the mixture was mixed in a primary mixer at 28% by weight of Masato 28%, Quarry Waste 56%, and 16% solids, and a high-strength mixed material was added to the solidified material and 1% of the solids were mixed. This is the case where the mixture of the clay powder is mixed in the second mixer with 82% of ocher powder and 18% by weight of solidified material, and the high-strength mixed material is produced by adding 1% and water to the surface layer.

As shown in Table 1, Examples 1 and 2 are similar in compressive strength, flexural strength, and water absorption, but in Example 2, the weight of the loess powder is high and the weight of the dolomite mill coat is low. When a part of the surface layer portion 20 is slightly attached to the mold of the pressure molding machine, and when the ocher sidewalk block 2 is separated from the mold of the vibration pressure molding machine, a large number of grooves are formed on the surface of the surface layer portion 20, resulting in poor aesthetics and expensive loess. Many powders are used to increase the cost of the ocher sidewalk blocks.

On the other hand, in Example 3, the compressive strength and the flexural strength absorption rate were lower than those in Example 1, and a considerable portion of the surface layer 20 was attached to the mold of the vibratory pressure molding machine, so that the ocher sidewalk block 2 was separated from the mold of the vibration pressure molding machine. When used as a sidewalk block becomes difficult.

The ocher sidewalk block of the present invention constituted as described above is divided into a base layer and a surface layer without forming the whole into ocher powder, so that only the surface layer includes ocher powder, thereby minimizing cost and being used as a sidewalk block while being released from the ocher. Far-infrared has the advantage of promoting blood circulation and metabolism when walking.

In addition, the ocher sidewalk block of the present invention, including the dolomite mill coat has the advantage of neutralizing the acid rain.

In addition, the ocher footpath block of the present invention, since it does not contain cement, it is environmentally friendly, there is an advantage that can be produced and mass production because it does not bake.

In addition, the manufacturing method of the ocher sidewalk block of the present invention minimizes the adhesion of the ocher powder to the mold of the vibrating press molding machine by dolomite mill coat, thereby improving the aesthetics of the finished ocher sidewalk block and producing the ocher sidewalk block easily and quickly. There is an advantage to this.
