Frame part 1 according to the first embodiment of the present invention is made of a mixture of aggregate weight of 1350kg / ㎥ ~ 1450kg / ㎥ unit weight, 27 ~ 38 parts by weight based on 100 parts by weight of the aggregate, blast furnace slag cement, blast furnace slag A binder of unit weight of 450 kg / m 3 to 490 kg / m 3 including all of elbow, calcined loess, calcined lime, kaolin, metakaolin, and waste glass regenerated powder; Preparation is made of a block composition for ecological restoration comprising 25 to 30 parts by weight of water based on ~ 1.5 parts by weight of a water reducing agent (SP) and 100 parts by weight of the binder.

Aggregate is used by mixing crushed aggregate and recycled aggregate, and the particle size of crushed aggregate or recycled aggregate has a size in at least one of 25mm ~ 50mm, 20mm ~ 25mm, 15mm ~ 20mm, 8mm ~ 13mm or 1mm ~ 3mm. . In addition, the mixing ratio of the crushed aggregate and the recycled aggregate is mixed in a mixing ratio of at least one of 5: 5, 7: 3 or 3: 7.

Crushed aggregates are aggregates made by crushing rocks taken from mines or quarries.

The recycled aggregate is mixed with at least one of waste concrete, waste ceramics, waste tiles, waste boards or waste panels. The components constituting the recycled aggregate are crushed and mixed below a predetermined particle diameter.

In addition, the binder material is blast furnace slag cement 30-53% by weight, blast furnace slag 11-16% by weight, calcined lime 7-10% by weight, calcined ocher 15-20% by weight, elvan 7-12% by weight, kaolin 7-12% by weight Are mixed.

This ecological restoration block composition is environmentally friendly by having a characteristic of low toxicity than the structure made of concrete.

And, the binder is blast furnace slag cement 30-53% by weight, blast furnace slag 11-16% by weight, calcined lime 7-10% by weight, calcined ocher 15-20% by weight, elvan 7-12% by weight, kaolin 7-12% by weight Is preferably mixed.

Here, calcined ocher is a loess activated by rapidly cooling general ocher at 900-1000 ° C. by using air, and when the calcined ocher is pulverized to have a constant particle size and mixed with hydrated lime, curing is performed through a pozzolanic reaction. The original physical properties and effects of the loess can be maintained.

The ecological restoration block composition used in the porous ecological protection block for river ecological restoration according to the first embodiment made as described above is when the calcined ocher mixed in the binder is less than 15% by weight or kaolin is less than 7% by weight. , Since the vegetation block produced using the ecological block composition has a strong alkalinity, microorganisms that grow in the water are reduced, which adversely affects the water quality. When calcined ocher exceeds 20% by weight or kaolin exceeds 12% by weight, the bonding strength of the ecological restorative block composition is weakened, making it difficult to secure the minimum strength. And if you do not put more than 7% by weight of lime, the binding force is weakened to the limit of 7 to 10% by weight.

Ecological restorative block composition used in the porous ecological protection block for river ecological restoration according to the second embodiment of the present invention other than the binder is maintained in the same manner as the first embodiment.

The binder according to the second embodiment, the blast furnace slag cement 30 to 53% by weight, the blast furnace slag 11 to 16% by weight, the calcined lime 7 to 10% by weight, the calcined ocher 15 to 20% by weight, the elvan 7 to 12 By weight and 7-12% by weight of the metakaolin was used in combination. That is, the binder according to the second embodiment was mixed with metakaolin instead of kaolin in the binder of the first embodiment.

The third embodiment of the present invention is also mixed with only the binder in the first embodiment as in the second embodiment, the binder according to the third embodiment, the blast furnace slag cement 30 ~ 53% by weight, the blast furnace slag 11 to 16% by weight, 7 to 10% by weight of the waste glass powder, 15 to 20% by weight of the calcined ocher, 7 to 12% by weight of the elvan and 7 to 12% by weight of the kaolin were used.

The binder according to the third embodiment was mixed waste glass powder which can replace the slaked lime in the binder of the first embodiment. Waste glass powder contains more than 10% of CaO, making it an eco-friendly material that can replace slaked lime. However, when more than 70% of the components added to more than 10% of the silica component of SiO ₂ causes strength problems, the mixing ratio was determined so that the range is 7 ~ 10%. The mixing ratio of such slaked lime is obtained through various case test results as shown in Table 1 below.

The fourth embodiment of the present invention is also mixed with only the binder in the first embodiment as in the second embodiment, the binder according to the fourth embodiment, blast furnace slag cement 30-53% by weight, blast furnace slag 11-16 Wt%, waste glass regenerated powder 7-10% by weight, calcined ocher 15-20% by weight, elvan rock 7-12% by weight and metakaolin 7-12% by weight were used. That is, in the binder according to the fourth embodiment, the waste glass regenerated powder and metakaolin were mixed in place of the slaked lime and kaolin in the binder of the first embodiment.

Next, Tables 1 to 4 show physical property tests of paste specimens prepared using the binder according to the first to fourth embodiments of the present invention, which are configured as described above.

First, Table 1 shows the characteristics according to the mixture of blast furnace slag, slaked lime, calcined ocher, ganban stone, kaolin, metakaolin and waste glass powder except for the blast furnace slag cement in the binder material in the form of 5cm × 5cm × 5cm cubic This is the result of the experiment.

[Table 1] Paste Properties Test

As shown in Table 1, the characteristics of the binder varied according to the mixing of slaked lime, calcined loess, elvan, kaolin, metakaolin and waste glass powder. As a result of the test of the compressive strength of the binder, when the slaked lime, kaolin and metakaolin were mixed, the bonding strength was excellent compared to the other cases, and the pH value also showed almost the neutral value. When the waste glass powder, kaolin and metakaolin were mixed, the hydration reaction occurred due to the CaO component of the waste glass, thereby securing sufficient strength in the binding force.

Based on the above test of compressive strength and pH of the physical properties of the paste, the actual porous specimens were prepared and tested for freeze-thaw resistance, pH, water purification efficiency, and plant growth according to recycled aggregate content.

Tables 2 to 4 below show the measurement results of the physical properties of the block composition for ecological restoration according to the first to fourth embodiments of the present invention according to the mixing ratio of the crushed aggregate and the recycled aggregate.

The first embodiment is referred to as the first embodiment, the second embodiment to the second embodiment, the third embodiment to the third embodiment, and the fourth embodiment to the fourth embodiment.

In this case, the ecological restorative block composition was prepared as a 10 cm × 10 cm circular specimen with a compressive strength specimen and measured by 100 ton UTM. The pH was measured after 24 hours by putting each specimen into 1 liter of distilled water. Resistance measurement against freezing and thawing was measured by comparing the compressive strength after 100 cycles with the initial compressive strength.

[Table 2] Property test results (crushed aggregate: recycled aggregate mixing ratio of 7: 3)

[Table 3] Test results of product physical properties (crushed aggregate: recycled aggregate ratio is 5: 5)

[Table 4] Experimental results of physical properties of samples (crushed aggregate: recycled aggregate ratio 3: 7)

As a result of measuring the compressive strength as shown in Table 2 to Table 4, in Examples 1, 2, 3, and 4, as a porous bed protection block for river ecological restoration, sufficient strength and voids were secured, and even though the proportion of recycled aggregates increased, There was little difference in strength and freeze thaw resistance.

In addition, it is judged that there is no significant difference in compressive strength compared with the composition using only ordinary Portland cement of the comparative example. In addition, Examples 1 and 2 showed a pH value of about 8.0 ~ 8.2, showing almost neutral properties, and a mixture of slaked lime and metakaolin showed high compressive strength and waste glass powder. In the kaolin mixed formulation, it was found to have a pH-lowering effect. This is effective in causing hydration reaction of calcined lime and metakaolin at high temperature, and when mixed below 7-10% by weight, there is a problem in securing strength, and even when mixed with 7-10% by weight or more, the strength efficiency is not clearly seen.

However, in Examples 1, 2, 3, and 4, the difference in strength and pH value did not differ much, and the resistance to freeze-thawing was proportional to the compressive strength. By securing the strength, the durability problem seems to be solved. Therefore, Examples 1, 2, 3, and 4, respectively, its physical properties and functions are judged to have excellent effects as a manufacturing technology of the ecological restoration block composition for making a porous river protective block for river ecological restoration.

On the other hand, Table 5 shows the water efficiency test according to the first to fourth embodiments, the two items of the BOD and SS were measured for the specimens of the first to fourth examples, respectively.

After installing 10 sets of porous bed protection blocks for river ecological restoration according to the present embodiment in a water channel having a width of 1 m and a length of 10 m, the water purification efficiency was measured. At this time, 30 water purification blocks were added to each set, and the average concentration was measured 10 times every 30 minutes after passing 10 m of water through an influent having an average concentration of BOD: 100 and SS: 70.

BOD: Biochemical Oxygen Demand SS: Total Nitrogen

As shown in Table 5, the average concentration of influent and effluent was reduced by more than 40 ~ 50% of BOD and SS due to the adsorption and filtering effect of the ecological restorative block composition in Examples 3 and 4, in which no lime was mixed. It has strong adsorption, mineral elution, ion exchange, far-infrared radiation, adsorption / decomposition of harmful substances and heavy metals due to the mixing of waste glass powder and kaolin, which improves compressive strength and freeze-thawing resistance, and grows plants. It has the effect of promoting and purifying the water, and the range of the most efficient purification efficiency is found to be 7 to 10% by weight. If it exceeds 7 to 10% by weight, the bond strength becomes weak and it does not secure the resistance to freezing and thawing. . And, compared with the comparative example using the Portland cement, there was a clear water purification effect.

Table 6 below shows the fabrication of the porous bedside protection block for river ecological restoration using the ecological restoration block composition according to the first to fourth embodiments, and then experimented with the plant growth in the porous bedside protection block for river ecological restoration One result.

At this time, the plant growth experiment was limited to the product of the aggregate size of 20 ~ 25mm, the pores between the product was filled by mixing the material mixed with peat, purified water sludge, combustion material in a weight ratio of 6: 3: 1 with water. And the product of each Example was filled on the soil of good quality, the soil was covered by about 5cm on top of it, so that Tolsque seed was seeded at a density of 100 grains / ㎠.

As shown in Table 6, as a result of comparing Examples 1 to 4 with the comparative example, there was almost no difference in the germination rate of the first week, and began to show a difference in the height after 3 weeks, Examples 1 to Example Growth was superior to the tetravalent comparative example. In addition, the case of Example 3 and Example 4 showed the best results. This is because Examples 3 and 4 showed the function of moisturizing water and pH closer to neutral.

In the case of Example 1 and Example 2, but also not large, the growth was better than the comparative example, and 6 weeks after sowing, the growth of the plant showed a significant difference. In particular, the case of Examples 3 and 4 is shown to form excellent plant growth conditions compared to the other examples. This results in a significant decrease in pH in the mixture of elvan, kaolin and waste glass powder, and shows the optimum growth conditions for plant growth.

In addition, in the case of Examples 1 and 2, the experimental results showed that the kaolin mixture was more favorable in the plant growth conditions than in the case where the metakaolin was added, but Examples 1 and 2 were compared with the comparative examples. In fact, it was found that there is sufficient plant growth promoting effect as an ecological block.
