The present invention relates to an unbaked soil sidewalk block and a method of manufacturing the same, and more particularly, to an environment-friendly unbaked soil sidewalk block and a method of manufacturing the same, which are manufactured without a firing process or addition of cement.

Conventional soil foot block is to express the strength by promoting the solid phase reaction between clay particles in the firing process by high heat of 1200 ℃ or more.

However, the conventional soil walkway block has a problem in that harmful substances are released into the atmosphere during combustion of fuel in the firing process, causing environmental pollution and energy consumption.

Meanwhile, Korean Patent Publication No. 10-0495026 discloses a hydroxide, sulfate or carbonate of sodium, potassium or lithium, based on 100 parts by weight of a mixture consisting of 50 to 90% by weight of clay, 5 to 40% by weight of coal ash, and 5 to 40% by weight of blast furnace slag. As a mixture of a selected one and a liquid silicon compound, the mixing ratio of the uncured high-strength clay brick is molded and dried by adding 15% by weight of a curing accelerator having a mixing ratio of 1: 1 to 3: 1 by weight, The high-strength clay brick is used to build a building, etc., since the raw material composition is different from the soil walkway block placed on the ground, the compressive strength and the bending strength is not sufficient, there is a problem that its application is difficult.

The present invention has been made in order to solve the above problems of the prior art, it is an object of the present invention to provide a method for producing a non-bending soil footpath block to protect the production cost and environmental protection because it is produced without a high temperature firing process.

Another object of the present invention is to provide an environmentally friendly unbaked soil footpath block without adding cement to develop strength.

Method for producing unbended soil walkway block according to the present invention for solving the above problems is Masato, quarry waste, slaked lime, solid fire, Masato 30-40%, quarry waste 40-50%, slaked lime 5-10%, A first step of mixing in a blender at a weight percentage of 10 to 20% solids and adding water to mix; A second step of putting the mixture mixed in the first step into a vibrating pressure molding machine to vibrate and press to form the soil footpath block; A third step of naturally curing the soil walkway block formed in the second step; After the third step is characterized in that it comprises a fourth step of steam curing the natural cured soil walkway block in the third step at 60 ℃ to 100 ℃ for 8 to 12 hours.

In addition, the third step, characterized in that carried out for 1 hour to 3 hours.

The method may further include a fifth step of natural curing for 10 to 14 hours after the fourth step.

The method may further include a sixth step of naturally curing the soil walkway block after the fifth step to naturally cure for 8 to 12 days.

 The unbaked soil walkway block according to the invention is characterized in that it is produced by the above production method.

The unbaked soil footpath block is characterized in that the width 250mm, length 125mm, height 60 ~ 80mm.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

    1 is a diagram of an embodiment of an unbended soil walkway block in accordance with the present invention.

As shown in FIG. 1, the uncurved soil walkway block is formed in a hexahedron shape or a rhombus shape as a whole, and does not use cement, and uses masato, quarry waste, slaked lime, and solid fire. It is prepared by mixing 40%, quarry waste 40-50%, calcined lime 5-10%, solids 10-20% by weight and adding water.

The slaked lime reacts with masato and quarry waste and neutralizes the mixture.

In addition, the solidified material is to harden the masato, quarry waste, and do not use cement-based solidified materials, and those having low iron content in steel-making sludge and dust are preferably used.

In addition, the water is added to the blender of about 20 to 40% by weight of the mixture of the masato, quarry waste, slaked lime, solidified material.

The non-baking soil sidewalk block is made of a width of 250mm, length 125mm, height 60 ~ 80mm.

Figure 2 is a flow chart showing a first embodiment of a method for producing unbaked soil walkway block according to the present invention.

As shown in FIG. 2, the method for producing unbended soil walkway block is uniformly mixed in a blender at a weight percent of Masato 30%, Quarry Waste 48%, Slaked Lime 5%, and Solidified Fire 17%, and water. Add and mix. (S1)

Thereafter, the mixture is put into a vibration press molding machine and pressurized by vibration 5 to 6 seconds and compression 3 to 5 seconds to form a soil footpath block. (S2)

Then, take out the molded soil footpath block from the vibrating pressure molding machine and natural curing for 2 hours. (S3)

After the natural curing put the soil sidewalk block into the curing chamber where the steam is ejected steam curing at the curing temperature 60 ~ 100 ℃ for 10 hours. (S4)

In the above steam curing, the soil walkway block is increased in strength and hardened.

After the steam curing, take out the soil sidewalk block in the curing room and finally natural curing for 12 hours. (S5)

In the natural curing as described above, the soil walkway block is more firmly solidified as the strength is gradually increased.

Finally, the natural cured soil footpath block was cured for 12 hours to naturally cure for 10 days. (S6)

Then, the 10-day natural cured soil walkway block is hardened more firmly in the natural curing for 12 hours while the strength is sufficiently secured in the steam curing, so that no natural curing is required for about 20 days. If you cure naturally only for a day, it will have the strength to be released as a product.

Figure 3 is a flow chart illustrating a second embodiment of a method for producing unbended soil walkway block according to the present invention.

As shown in Fig. 3, the method for producing unbended soil footpath block is uniformly mixed in a blender at 30% by weight of Masato 30%, quarry waste soil 50%, calcined lime 5%, and solidified fire 15% and water. Add and remix (S1 ')

Thereafter, the mixture is put into a vibrating pressure molding machine as in Example 1, pressurized by vibration for 5 to 6 seconds and compressed for 3 to 5 seconds to form a soil footpath block.

Then, the molded soil footpath block is cured through the same curing process as in Example 1. (S3) (S4) (S5) (S6)

Figure 4 is a flow chart illustrating a third embodiment of a method for producing unbended soil walkway block according to the present invention.

As shown in Fig. 4, the method for producing unbended soil walkway block is uniformly mixed in a blender at 40% by weight of Masato 40%, quarry waste soil 40%, calcined lime 5%, and solidified fire 15%, and water is added thereto. To mix again (S1 ″).

Thereafter, the mixture is put in a vibration press molding machine as in Example 1 and press-molded with a vibration of 5 to 6 seconds and a compression of 3 to 5 seconds.

Then, the molded soil footpath block is cured through the same curing process as in Example 1. (S3) (S4) (S5) (S6)
