DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited thereto. In the following description, components having the same reference numerals in different drawings have similar functions, so that they will not be described repeatedly unless necessary for an understanding of the invention, and the known components will be briefly described or omitted. However, It should not be understood as being excluded from the embodiment of Fig.

FIG. 1 shows an embodiment of a method for manufacturing a construction material of a water-based light-absorbent basic lightweight carbon-based material according to the present invention.

Referring to FIG. 1, a method for manufacturing a construction material of a plant light-absorbent basic lightweight carbon series comprises: (P11) milling a first recycled aggregate containing an adsorbent of a water purification plant so as to have an average diameter of 5 mm or less; (P12) of pulverizing the second recycled aggregate containing waste glass to an average diameter of 8 mm or less; Making an additive comprising lime dust and silica dust; Mixing the first recycled aggregate and the second recycled aggregate while injecting water and cement and an additive and stirring the same to form a formed material (P13); (P14) molding and curing the molding material in a shape according to the application, wherein the first recycled aggregate and the second aggregate aggregate each comprise 30 to 60 wt% and 20 to 40 wt% .

The carbonaceous material can be made from a plant site adsorbent, and the plant site adsorbent can include activated carbon or a filter paper. The filtering paper of the water purification plant can be used for removing various kinds of microorganisms or chemical substances such as powdered activated carbon, granular activated carbon or biological activated carbon, and the filter can be disposed below the activated carbon to purify the water. The carbonaceous aggregate can be prepared by using a pulp adsorbent or a pulmonary filtration material which is used in the filtering paper of the water purification plant and then replaced in accordance with the replacement cycle. The waste activated carbon or the waste filter can be dried to be used as the first recycled aggregate and may be dried at a temperature of 100 to 500 ° C, for example, for removing and crushing harmful components, if necessary, but not limited thereto Do not. The first recycled aggregate may include anthracite and may be generated as waste at various sites. The anthracite can be a small particulate form with ash containing a large amount of carbon and can be made to have an average diameter of, for example, 0.5 to 5 mm.

The first recycled lightweight aggregate may comprise waste filtration yarn or gravel, and the waste filtration yarn or filtration sieve may be a filter yarn used in filter paper of a water treatment plant or a filter yarn produced in various work sites. The first recycled aggregate may contain 30 to 50 wt% of pulmonary anthracite based on the total weight of the first recycled aggregate; From 40 to 60 wt% of waste filtration yarn or filtration saris; And 5 to 15 wt% of waste activated carbon. However, the present invention is not limited thereto. When the first recycled aggregate is prepared in this way, a second recycled aggregate to be mixed with the first recycled aggregate can be produced (P12).

The first recycled aggregate may be made of a material which is made of a relatively heavy material and which is hardened in advance when the second recycled aggregate is made of a lightweight material. The second recycled aggregate may be made of, but not limited to, waste glass, refractory, waste ceramic, waste or similar industrial waste. The second recycled aggregate may be made of a material having a large hardness or strength as a whole as a heavy material. The second recycled aggregate may be pulverized to have an average diameter of 6 to 9 mm, for example, by a device such as a pulverizer. When the second recycled aggregate is prepared (P12), additives and auxiliary materials can be prepared (P13).

The additive may be a material for improving the bonding force between the first recycled aggregate and the second recycled aggregate, such as, for example, lime dust or silica dust. The lime dust or siliceous dust may be a result of various waste disposal processes occurring in the industrial field and may be made in the form of a powder having an average diameter of 10 μm to 1.0 mm. Additives such as loess, fly ash, lime or alumina (Al ₂ O ₃ ) may also be added as adjuvants. The adjuvant may be made to have the same or similar average diameter as the additive, and may be uniformly mixed with the additive. The additives and auxiliaries thus prepared can be added together with water during the production of building materials (P14).

The first recycled aggregate and the second recycled aggregate may be mixed into a device such as a blender and the additive / adjuvant may be added in a predetermined amount in the mixing process. Mortar or cement may be added thereto to form a brick, type or block. The first recycled aggregate, the second recycled aggregate, and the additive / adjuvant may be mixed in a predetermined amount for molding of the building material. For example, in a weight ratio of the first recycled aggregate: the second recycled aggregate: the additive: the adjuvant = 50: 25 to 35: 10 to 20: 3.

The cement may be introduced during the molding process or during the mixing process accompanied by stirring, for example, cement such as pot land cement may be added in an amount of 3 to 12 wt% of the total weight of the material described above. Once the mixing process is complete, it can be cured for 3 to 20 hours, for example in the form of bricks, tiles, blocks or similar building materials. Curing or curing may be accomplished by methods such as natural curing at room temperature, curing with water vapor, or curing with carbon dioxide. Curing with water vapor can be achieved at a spraying pressure of, for example, 3 to 8 kg / cm < 3 > of water vapor at a temperature of 75 to 95 < 0 > C. Further, the curing by carbon dioxide can proceed with curing by water vapor, and the water vapor containing carbon dioxide dissolved in the saturated state can be sprayed on the building material.

The cured building material can be a construction material similar to concrete or cement brick, and can be a recycled construction material including waste activated carbon, waste filter paper, and silica dust in a water purification plant.

- 45 to 55 wt% lightweight aggregate consisting of pulp anthracite, waste filter paper and waste activated carbon

25 to 35 wt% recycled aggregate containing waste glass and having an average diameter of 5 to 8 mm

- 10 to 20 wt% additive consisting of lime dust and silica dust

- 3 to 8 wt% of auxiliaries consisting of alumina and loess

And as described above, the cement may be 3 to 12 wt% of the total composition given above. In the proposed components, the pulmonary anthracite, pulmonary filtration, and activated carbon can be obtained from the adsorbent of the water purification plant, and all of the remaining components can be obtained from the waste of the operator. As described above, the construction material according to the present invention is made from wastes generated in a water purification plant or a business site, thereby enabling the waste to be recycled while reducing the waste treatment cost.

The process of making recycled construction materials is explained below in detail.

FIG. 2 shows an embodiment of the carbon aggregate production process and the recycled aggregate production process of the embodiment shown in FIG. 1.

Referring to FIG. 2, the carbon aggregate production process or the recycled aggregate production process includes the steps of: (P21) supplying a predetermined amount of recycled material; Removing iron or similar metal components from the recycled material (P22); (P23) grinding the metal-removed material to be suitable for the first recycled material or the second recycled material; A step (P24) of removing components not suitable for the building material from the crushed material; (P25) adjusting the average diameter to be suitable for the first recycled material or the second recycled material; And adjusting the pH of the material to neutralize (P26).

As described above, the first recycled aggregate corresponding to the carbon aggregate may include pulp anthracite, waste filter paper, and waste activated carbon. The second recycled aggregate may also include waste glass, waste ceramics, waste ash, waste refractory or mortar. The first and second recycled aggregate may be fed in a predetermined amount while being conveyed through a conveying means such as a conveyor. The first recycled aggregate is the material used as the absorbent of the water purification plant, so moisture can be controlled before it is conveyed to the conveyor. For example, means capable of supplying dry hot air to the lower side, the side surface, or the upper side of the conveyor on which the first recycled aggregate is conveyed may be disposed so that the level included in the first recycled material can be adjusted. By such moisture control, the water content of the first recycled material can be adjusted, for example, to 1 to 10 wt%. If necessary, the second recycled aggregate can be controlled in moisture by the same or similar method as the first recycled aggregate. In this way, the first recycled material or the second recycled material can be conveyed by the respective conveying means while the water content is controlled. In order to supply a fixed amount, the conveying speed is controlled by each conveying means, Measuring means can be arranged.

During the conveying process or after the conveyance is completed, the first and second recycled aggregate materials may be subjected to a de-ironing process. For example, the de-ironing process may be performed by the electromagnetism de-ironing device. For example, the de-ironing process can be carried out by arranging bar-shaped magnets along the conveying direction on both sides of the conveyance path, or by placing the movable electromagnets above the conveying means. The de-ironing process can be carried out in various ways and is not limited to the illustrated embodiment. The crushing process for the recycled aggregate can be proceeded by the crusher (P23) while the de-ironing process is proceeded or the process is completed (P22). The first and second recycled aggregates can be made to have a predetermined average diameter through the grinding process, and for example, the first and second recycled aggregates can be pulverized to have an average diameter of 5 mm and 8 mm respectively (P23). When the first and second recycled aggregates are crushed to a predetermined size, the sorting is removed by the separator, and a material having an inappropriate size or size can be separated (P24). The sorter may have a structure of, for example, a sieve structure while stirring at a temperature of 70 to 150 ° C. By this drying and stirring, water and harmful components can be completely removed from the components of the first recycled aggregate composed of the waste adsorbent component, and at the same time, the waste anthracite, the waste activated carbon and the waste filter can be uniformly mixed with each other. When the selection of the first and second recycled aggregates is completed in this way, the particle size adjustment process may proceed (P25).

Particle size control refers to adjusting the weight ratio of 1 or 2 recycled aggregates having different diameters according to different diameters. Particle size control can be made between 1 and 2 recycled aggregates for each of the first and second recycled aggregates. Grain size control can be a key process to determine the hardness, strength, warmth or durability of manufactured construction materials. The particle size adjustment to the first recycled aggregate is 70 to 90 wt% with respect to the total weight of the first recycled aggregate, and the ratio with the average diameter of 1 mm or less is 5 wt% Or less. And the ratio of the second recycled aggregate having an average diameter of 8 to 6 mm is 60 to 80 wt%, so that the second recycled aggregate can be selected not to be larger than the weight ratio of the first recycled aggregate having an average diameter of 4 to 5 mm. And the proportion having an average diameter of 3 mm or less may be selected to be 5 wt% or less. By controlling the particle size of the first recycled aggregate and the second recycled aggregate in this way, the construction material can have a predetermined physical or chemical property. In this way, when the particle size regulating process for the first recycled aggregate and the second recycled aggregate proceeds (P25), the neutralization process can proceed to the second recycled aggregate (P26).

The neutralization process may have the function of removing the harmful components remaining in the second recycled aggregate while adjusting the pH of the second recycled aggregate. The neutralizing agent may include, for example, magnesium, a pH adjusting agent, limestone, quicklime, slaked lime, carbide or similar components, and may preferably include materials such as benzonite, diatomaceous earth or polyvinylpyrrolidone. The neutralizing agent may be added in an amount of 0.1 to 5 wt% based on the total weight of the second recycled aggregate, and may be added in a liquid state or in a powder state.

When the first recycled aggregate and the second recycled aggregate are made into a shape that can be made into a building material in this way, they can be mixed with each other and molded.

FIG. 3 shows another embodiment of the manufacturing process of the building material according to the present invention.

Referring to FIG. 3, the first recycled aggregate and the second recycled aggregate may be stored in the first and second hoppers 31 and 32, respectively. Additives and auxiliaries may also be stored in a first storage silo 34, and cement and water may be stored in a second storage silo 35 and a water tank, respectively. Then, as each of the materials is fed into the mixer 36, water can be supplied from the water tank and mixed. And then molded into a brick, block or tile form, which can be made into a building material with natural curing, steam curing or carbon dioxide curing as described above in the curing plant 37. The bricks made in this way are shown in Fig.

The construction material made in this way is lightweight, environmentally friendly, has excellent antibacterial properties, excellent sound insulation performance, and can be used as an interior finishing material because of its beautiful surface treatment.
