In particular, in the mixing and molding process, the bottom ash is mixed with the cement and water for each particle diameter, and then a large particle diameter is put into the mold and vibrated, and a small particle diameter is put into the mold and pressed. You may shape in order.

In addition, the particle diameters of the royal yarn, the heavy yarn and the fine yarn of the bottom ash may be 25 to 50 mm, 13 to 25 mm, and 13 mm or less, respectively.

In this case, the bottom ash may be mixed with the cement and water for each particle diameter, and then, the particles having a large particle size are added to the mold and chopped, and the particles having a small particle diameter are added to the mold to be vibrated and pressurized. .

The mixture may further include colored pigments in a blending ratio of 6% or less within a total range of 100%.

In addition, instead of the bottom ash, it is also possible to apply the waste concrete that is crushed and recycled into royal sand, heavy sand and fine sand, respectively, depending on the particle size.

In addition, the sand, gravel and stone powder may be applied to the recycled by crushing the waste concrete to the size of conventional sand, gravel and stone powder.

Meanwhile, G.R. according to the present invention. The plant protection block is manufactured according to any one of the above-mentioned manufacturing methods.

Hereinafter, the configuration of the present invention will be described in detail, but the manufacturing method of G.R. (Good Recycled) plant protection block will be mainly described, and G.R. The plant protection eye block will be additionally briefly described, and specific details thereof will be replaced with descriptions of the manufacturing method.

First, the most important raw material of the plant protection block disclosed by the present invention is the bottom ash, which is a post-combustion product of pulverized coal used as fuel in thermal power plants, or discharged from construction and civil works and demolition sites. It is waste concrete.

In particular, the bottom ash is discharged from the thermal power plant is generated through the following process. In other words, most coal-fired power plants use pulverized coal combustion.In general, about 80% of the coal is finely pulverized to a particle size of 74 μm or less and then air is mixed with the air. The coal ash of the combusted pulverized coal is discharged from the boiler together with the flue gas. More than 80% of the coal ash is a fly ash collected in the lower part of the dust collector, and more than 65% of the fly ash is composed of a particle diameter of 10 μm or less, and a mass falling in the lower part of the boiler or Coarse ash of coarse particle size is called bottom ash. Conventionally, the bottom ash has been recycled for coastal reclamation, swampy or lowland reclamation, but due to the limited demand of the landfill site, the amount of waste that cannot be recycled is increasing.

In one embodiment of the present invention, this bottom ash is recycled to G.R. To prepare a plant protection block, the process is as follows.

First, the bottom ash is crushed into royal sand, medium sand and sesame seeds, respectively, and mixed at the same ratio. Particularly, the royal yarn, the heavy sand and the fine sand are those having a particle diameter of 25 to 50 mm, 13 to 25 mm, and 13 mm or less, respectively, which is the most preferable size for the formation of voids for vegetation / planting.

In the next step, 25 to 75% (bottom%) of the bottom ash, which is the main raw material, 15% or less of sand, 22% or less of gravel, 15% or less of stone powder, 8-15% of cement, Then, the mixture is mixed at a blending ratio of 7 to 10% of water, and these blending ratios are the most suitable blending ratios for the strength and formability of the plant protection block to which the present invention is disclosed, and the formation of an appropriate amount of pores. Various modifications can be made within the above compounding ratio range, as in the above.

The mixture mixed at such a mixing ratio is introduced into a mold having a preliminary shape, and then vibrated by a vibrator and pressurized by a hydraulic molding machine, thereby forming. At this time, the addition of the mixture may be prepared by dividing the primary and the secondary, or may be prepared by simply vibrating and compressing both the primary and the secondary at a time without dividing into the primary and the secondary.

In particular, this mixing and molding process can be made according to the following examples. First, mix the cement and water for each particle size (e.g., 25-50mm, 13-25mm, and 13mm or less), respectively, and then apply a large particle size to the mold first and vibrate with a vibrator. After making it evenly, molding can be performed in order that a small particle diameter is put into a mold secondary and pressurized by a hydraulic molding machine. Alternatively, as another example, the bottom ash is mixed with cement and water for each particle size as described above, and then a large particle size is first put into the mold to be chopped first, and then a small particle size is added to the mold secondly. The furnaces may be molded in the order of vibration and pressurization, respectively. Here, aggregates other than the above-described cement and water, that is, sand, gravel and stone powder, may be mixed in the appropriate ratio mentioned above when the bottom ash is mixed with cement and water.

On the other hand, in consideration of the appearance of the lanyard block, in addition to the main raw material and the sub raw materials, the color pigments are further blended. Colored pigments such as red, orange, brown, black, green, yellow and blue are applied. At this time, as the colored pigment used, recycled iron oxide is best used for the purpose of the present invention.

After completion of the mixing and molding process as described above, the molded product is put into a curing chamber and cured according to a conventional curing method such as steam curing to obtain a final product.

On the other hand, in the present invention, instead of the bottom ash, G. R. using waste concrete discharged from construction and civil works and demolition site. It is also possible to prepare a plant protection block, in which case the waste concrete is crushed to the size of royal sand, heavy sand and sesame yarns like bottom ash, and specific details are the same as the method of manufacturing using the bottom ash as described above. The description is omitted.

In addition, the above description is based on the example of using natural aggregates such as sand, gravel, and stone powder as a raw material in addition to bottom ash and cement as raw materials for the manufacture of the raft block. It may be pulverized and used in place of the subsidiary materials. In other words, the waste concrete is blended according to the size of the sand, gravel, and stone and the mixing ratio of the above-mentioned G.R. To prepare a plant protection block, G.R. The plant protection block has a compressive strength of 210 kgf / cm 2 or more.

As such, when the waste concrete discharged from the construction and civil works and the demolition site is used, it may be very preferable in terms of the environment and economic effects that are difficult to convert to the amount of money in terms of recycling the waste.

Next, G.R. An example of the blending ratio of the main and subsidiary ingredients in the plant protection block is shown.

The blending ratios of the main raw materials and the sub raw materials applied in these examples are respectively G.R. The plant protection block is within the range of having excellent moldability and strength and an appropriate number of pores. On the other hand, as described above, instead of the natural aggregates such as sand, gravel, stone powder, etc., the waste concrete discharged from construction and civil works, and the demolition site, etc., pulverized and blended in accordance with the size and compounding ratio of these natural aggregates, It may be.

Based on this blending ratio, G.R. Pictures of plant protection blocks are illustrated in FIGS. 1 to 3, respectively. G.R. of the present invention. The plant protection block may be variously modified in any form as long as it is not only shown in the drawings but also the manufacturing method of the present invention can be applied. In the drawing, reference numeral 1 denotes a 'reinforcing bar', which is buried inside the block except at least a part to facilitate the fabrication, movement, and construction of the revetment block, and is hot-dipped to prevent corrosion. It is preferable to use one. In addition, reference numeral 2 denotes a 'vegetation / planting space', and other matters are the same as those of a conventional plant protection eye block, so a detailed description thereof will be omitted.

Such G.R. of the present invention. Since plant ash block contains various minerals and fertilizers in the bottom ash, which is the main raw material, it provides nutrients necessary for aquatic plants to grow when installed on banks of rivers, rivers, lakes and watersides. In addition, through the vegetation and planting space, not only trees and grasses such as willows can grow, but also moisture retention is maintained by voids formed inside and outside the plant protection block, so that various plants and microorganisms can inhabit. Therefore, it is very environmentally friendly.

As described above, the G.R. Method for preparing plant-side protection block and G.R. The plant protection block has a very advantageous effect in terms of manufacturing cost since the bottom ash, which is a waste after combustion of the thermal power plant, is recycled.

In addition, it is environmentally friendly because various plants and microorganisms can be inhabited by the ingredients contained in the bottom ash and the vegetation / vegetation spaces and pores (ie, the porous pores and the large holes of the vegetation spaces) formed in the bottom block itself. There is also a beneficial effect.

In addition, the manufacturing process is simple and easy compared to the raft block that recycled the existing waste building materials has excellent manufacturability.
