The blocks 10 constituting the body of the versatile vegetation block 1 use blocks made of tidal flats or cement blocks which are constructed so as not to cause water pollution while maintaining durability.

The block 10, which is produced using the tidal flats,

The molds were filled with 40 to 60 wt% of tidal flats, 20 to 40 wt% of soil, 5 to 20 wt% of cement and 2 to 7 wt% of curing agent, and the mixture was pressurized at 60 to 120 kg / ℃ for 2 ~ 4 days.

When the amount of the tidal flats is less than 40 wt%, there is a problem that the far infrared ray and the anion radiation property are deteriorated and the tidal flat recycling rate is low. When the tidal flats are used in an amount exceeding 60 wt%, the formability is inferior. It is preferable to limit it to a range of 40 to 60 wt% with respect to the total weight of the block.

When the amount of the soil used exceeds 40 wt%, the durability of the block may be lowered. Therefore, the amount of the soil used is preferably limited within a range of 20 to 40 wt% with respect to the total weight of the block.

If the amount of the cement is less than 5 wt%, the durability of the cement may be lowered. If the cement content exceeds 20 wt%, it is difficult to use the cement in an environmentally friendly manner. To 20 wt%.

The curing agent is hexamethylenetetramine or polyamide. When the amount of the curing agent is less than 2 wt%, the curing ability is deteriorated. When the amount of the curing agent is more than 7 wt%, the curing function is not significant, Is preferably limited to a range of 2 to 7 wt% with respect to the total weight of the block.

The production example of the block 10 manufactured using the tidal flats will be described in detail as follows.

The mold was filled with 50 wt% of tidal flats, 30 wt% of soil, 15 wt% of cement and 5 wt% of curing agent. The mixture was pressed into a mold at a pressure of 110 kg / .

The block 10 may also comprise 3 to 10 wt% of granular weathered soil; 3 to 8 wt% of loess powder; 5 to 20 wt% of composite slag aggregate formed by mixing blast furnace slag and steel slag at the same weight ratio; Porcelain 5 to 20 wt%; 3 to 10 wt% of silica fume; 1 to 5 wt% polypropylene fiber; 1 to 5 wt% of water glass; 35 to 60 wt% of cement; Crushed aggregate 7 ~ 30 wt%; 2 to 10 wt% of admixture; The mixture was stirred and mixed with 7 to 35 wt% of water, filled into a mold, pressurized at 60 to 120 kg / cm 2, dried at 120 to 180 ° C, and then calcined at 1,000 to 1,200 ° C. use.

The block 10 is made of environmentally friendly elements so as to maintain its durability and to prevent water pollution because it is required to maintain its shape for a long time in a state of being locked in seawater, river, ditch, stream or the like.

When weathered, rocks lose their cementing power as rocks and are eventually reduced to earth. The generated soil is called weathered soil.

Among the weathered soil, the residual soil which is weathered by the granitic rocks of the granitic rocks and the unburnt soil resulting from them is called granitized weathered soil.

The granular weathered soil is added to be used as a substitute aggregate. When the amount is less than 3 wt%, the granular weathered soil serves as a substitute for an aggregate. When the amount exceeds 10 wt%, the strength and durability of the cement block are lowered , The amount of the granular weathered soil used is preferably limited within a range of 3 to 10 wt% of the total weight of the cement block.

The loess is mainly composed of silt-sized particles, and it is mineral clay (clay) because it gets cold when it gets wet. And 'Loess' loosely bound by calcium carbonate. The chemical formula of the loess is represented by _{Al 2 O 3 · 2SiO 2 ·} 2H 2 O, the chemical composition are given in Table 1 below.

Sample \ Ingredients SiO ₂ Al ₂ O ₃ Fe ₂ O ₃ CaO MgO Other ocher 58.36 32.5 3.66 0.24 0.27 4.97

The above-mentioned loess is a block material containing 10 kinds of inorganic raw materials such as SiO ₂ , Al ₂ O ₃ and Fe ₂ O ₃ for copying far-infrared rays, so that it can smoothly metabolize human body by far-infrared ray radiation, It has the effect of removing moisture and odor.

The above-mentioned loess powder is added to reinforce the environment-friendly elements of the cement block. When the amount of the cement block is less than 3 wt%, the far-infrared radiation function is insufficient. When the cement block exceeds 8 wt%, the strength and durability It is preferable that the amount of the loess powder is limited within a range of 3 to 8 wt% of the total weight of the cement block.

The composite slag aggregate is formed by mixing blast furnace slag and steel making slag at a ratio of 1: 1 by weight. The composite slag is a granular blast furnace slag produced by quenching a blast furnace slag simultaneously with pig iron in a blast furnace The pulverized slag is pulverized into fine pulverized blast furnace slag powder,

The steelmaking slag is generated in the process of removing carbon and silicon components dissolved in the molten steel to refine steel and scrap iron to make steel.

The composite slag affects the strength and durability of the cement block. When the amount of the slag is less than 5 wt%, the effect on the strength and durability of the cement block is insignificant. When the amount exceeds 20 wt% The amount of the composite slag to be used is preferably limited within a range of 5 to 20 wt% of the total weight of the cement block.

Porcelain is added to give a high strength effect, and powders having a particle diameter of 0.3 to 2.5 mm are used.

When the amount of the magnetic material used is less than 5 wt%, the effect of increasing the strength by magnetic use is insignificant. When the amount of the magnetic material is more than 20 wt%, mixing with other components may not be properly performed. The amount used is preferably limited to a range of 5 to 20 wt% of the total weight of the cement block.

The silica fume is an industrial by-product obtained by collecting ferrosilicon or silicon metal of ferroalloy used as a deoxidation desulfurizing agent for steelmaking in a waste gas generated in an electric furnace. Generally, the specific gravity is about 2.2, the SiO ₂ content is over 90%, the pozzolanic reaction is very large, and the specific surface area of the particles is also very large, which is good for enhancing strength, securing long-term strength and improving durability.

Physical properties (Table 2) and chemical properties (Table 3) of silica fume are as follows.

density shape Diameter (탆) chief ingredient Specific surface area (cm 2 / g) 2.2 ± 0.05 rectangle 0.1 to 1 SiO ₂ 200,000

Chemical composition (%) SiO ₂ Al ₂ O ₃ Fe ₂ O ₃ CaO Na ₂ O K ₂ O MgO SO ₃ 94.0 0.7 0.3 0.4 0.5 1.3 1.5 -

When the amount of the silica fume is less than 3 wt%, strength enhancement, long-term strength and durability improvement are insignificant. When the amount of the silica fume is more than 10 wt%, mixing with other components is not properly performed. The amount of the silica fume to be used is preferably limited within a range of 3 to 10 wt% of the total weight of the cement block.

The polypropylene fibers are produced by extruding the polypropylene fiber resin or small grains into a plate in a molten state as a chemically inert hydrocarbon polymer processed into a highly crystalline film-like material. The mechanical properties of PP fibers can be significantly improved by the combination of various fillers. PP fiber does not absorb water, does not react, has excellent resistance to acids and bases. It does not absorb water and it does not change water-cement ratio of concrete or shotcrete because it is superior to other fiber materials such as cotton and cotton.

By adding the PP fiber, the cement block 10 can reduce cracking due to plastic shrinkage, improve the waterproof property of the water-immersed structure and the toughness of the concrete.

When the amount of the polypropylene (PP) fiber is less than 1 wt%, the effect of reducing the crack due to plastic shrinkage and the effect of improving the waterproofness of the structure immersed in water and the toughness of the concrete are insignificant. It is preferable that the amount of the polypropylene (PP) fiber is limited within a range of 1 to 5 wt% of the total weight of the cement block.

The water glass acts as a hardening material of the granulated weathered soil, thereby solidifying the cement block 10 to solidify it, thereby stabilizing the pores.

When the amount of the water glass used is less than 1 wt%, the curing ability of the weathered granite soil is deteriorated. When the water glass exceeds 5 wt%, the water glass is used more than necessary and is inefficient. Therefore, To 5 wt%.

If the amount of the cement used is less than 35 wt%, the overall physical properties such as moldability and durability are deteriorated. If the amount exceeds 60 wt%, the cement is used more than necessary and is inefficient. To 35% by weight and 60% by weight, respectively.

The amount of the crushed aggregate is preferably limited within a range of 7 to 30 wt% of the total weight of the cement block in consideration of uniform formulation and improvement of durability.

The above-mentioned admixture is used for enhancing the low dispersibility due to the addition of silica fume or the like used for the purpose of improving the strength, and a high-performance AE water reducing agent is used.

More specifically, the high-performance AE water reducing agent is a polycarboxylic acid type and has a specific gravity of 1.04, and is a light yellow, liquid state admixture. The physical properties of the high performance AE water reducing agent are shown in Table 5 below.

Category \ Item importance shape pH chief ingredient toxicity High performance
AE water reducing agent 1.04 Light yellow liquid 11.5 ± 1.5 Polycarboxylic acid series none

When the amount of the admixture is less than 2 wt%, it is difficult to increase the dispersibility. When the amount exceeds 10 wt%, the amount of the admixture is inadequate. Therefore, the amount of the admixture is preferably 2 to 10 wt% Of the total amount of water.

If the added amount of water is too small, uniform mixing is not achieved and the viscosity is not increased due to an increase in viscosity. In case of too much water, there is a risk of cracking during prolonged drying and firing, To 7 to 35 wt% of the total weight of the cement block.

The production example of the block 10 will be described in detail as follows.

Granite weathered soil 5 wt%; 3 wt% of loess powder; 5 wt% of composite slag aggregate formed by mixing blast furnace slag and steel slag at the same weight ratio; Porcelain 5 wt%; Silica fume 5 wt%; 3 wt% polypropylene fiber; 2 wt% of water glass; 40 wt% of cement; Crushed aggregate 12 wt%; 5 wt% admixture; 15 wt% of water is stirred to prepare a mixture, and the mixture is injected into a mold mold to be filled.

That is, the block 10 shown in FIGS. 1 and 2 has a structure in which a plurality of connection grooves 10b are formed along the side of the planting grooves 10a.

The block 10 shown in Figs. 3 and 4 has a structure in which a plurality of wicker coupling grooves 10c are formed along the outer peripheral surface of the block 10 shown in Fig. 1 or Fig.

The planting groove 10a formed on the surface of the block 10 is a space for mounting the vegetation vessel 20 and the depth of the groove is equal to the height of the vegetation vessel 20.

The vegetation vessel (20) uses a biodegradable plastic, straw barrel or ocher vessel to prevent water pollution and protect fisheries.

3 to 10 wt% of a binder of green algae (Grateloupia elliptica)

1 to 2 wt% of polypropylene (PP) fiber,

5 to 10 wt% of starch,

A mixture of water and 16 to 40 wt% is molded into an extruder and then dried at room temperature for 1 to 3 days and then dried at 80 to 120 ° C for 1 to 2 hours.

When the amount of the loess is less than 51 wt%, the amount of water used is relatively increased, so that the vegetation vessel 20 is not properly formed, and cracks are generated in the drying process If the content exceeds 75 wt%, the viscosity becomes too high and moldability deteriorates. Therefore, the use amount of the loess is limited within a range of 51 to 75 wt% with respect to the total weight of the vegetation vessel 20 .

The binder uses a paste prepared by using red algae true gambling (Grateloupia elliptica).

Seaweeds include red ginkgo (red gambling), mugwort, black crab, blue crab, and brown algae, seaweed, and tortoise. Among these, good adhesion is a true gamble of red algae.

The true gambling has the highest adhesive strength because it contains a lot of sugar. After washing the true gambling with water and drying it, use it to pull the paste and use the filtered out residue as a binder.

When the amount of the binder is less than 3 wt%, the durability of the vegetation vessel is deteriorated due to weak binding force. When the amount of the binder is more than 10 wt%, the uniform composition of the materials is difficult due to the increase of the viscosity, It is preferable to limit the amount of water to 3 to 10 wt% with respect to the total weight of the vegetation vessel 20.

The polypropylene (PP) fiber is the same as that used in the production of the block 10.

When the amount of the polypropylene (PP) fiber is less than 1 wt%, the strength enhancement effect of the vegetation vessel 20 is insignificant. When the amount of the polypropylene (PP) fiber is more than 2 wt% (PP) fiber is preferably limited to a range of 1 to 2 wt% with respect to the total weight of the vegetation vessel 20.

When the amount of the starch is less than 5 wt%, the effect of promoting the growth is insignificant. When the amount of the starch is more than 10 wt%, the starch is not necessary It is preferable that the amount of the starch used is limited within a range of 5 to 10 wt% with respect to the total weight of the vegetation vessel 20.

If the amount of the water used is too small, the viscosity of the water is too high to form, and if it is too much, there is a risk of cracking in the drying process. Therefore, the amount of water used is preferably 16 to 40 wt. %. ≪ / RTI >

A concrete production example of the vegetation vessel 20 using the loess is as follows.

The vegetation vessel 20 is composed of 65 wt% of loess, 5 wt% of a binder of green algae grass (Grateloupia elliptica), 2 wt% of polypropylene (PP) fiber, 7 wt% of starch and 21 wt% The mixture thus obtained is molded into a hexagonal shape by an extrusion molding machine, followed by primary drying at room temperature for 2 days and secondary drying at 80 ° C for 1 to 2 hours.

The vegetation vessel 20 is filled with vegetable soil for the planting of seaweeds or water purification plants.

The vegetation soil is composed of a mixture of 30.0 ~ 70.0 wt% of tidal flats, 25.0 ~ 50.0 wt% of loess, and 5.0 ~ 20.0 wt% of clay.

The soil composition of the vegetation soil is optimized for the growth of seaweed by using the tidal flats as a main component and is maintained in a constant shape in the vegetation vessel 20 through proper mixing of clay and loess, Lt; / RTI >

More preferable mixing composition of the vegetation soil is tidal flat 50 wt%, yellow soil 30 wt%, and clay 20 wt%.

When the connecting rod 30 is fixed in the connecting groove 10b as described above, the connection groove 10b of the other block 10 is inserted into the connecting rod 30 in the same manner, so that the connection between the block and the block is made.

FIGS. 8 to 11 illustrate the coupling between the blocks through such a coupling process. However, the present invention can be variously presented according to the coupling direction.

As shown in Figs. 14 and 15,

The versatile vegetation block 1 according to the present invention can plant seaweeds or water purification plants through the vegetation vessel 20, but in order to utilize the vegetation block 1 more efficiently, the outer peripheral surface of the vegetation block 1 A plurality of string joining recesses 10c are formed and the string 40 is mounted on the string joining groove 10c.

The barb 40 is made of straw and is natural-friendly because it is spontaneously decomposed when a certain period of time elapses in the water, and has the advantage of easy attachment of seaweeds, perennial seaweeds or spores thereof (see Fig. 15 )

The barb 40 may be obtained by attaching annual seaweeds, perennial seaweeds or their spores,

The mixture prepared by mixing 80 ~ 95 wt% of extract and 5-20 wt% of red algae japonica (Grateloupia elliptica), which were extracted with the same weight ratio of kelp and tortoise, was applied to the surface of vegetation and dried for 1-2 days will be.
