{The Methods to Manufacture an Environmentally Friendly, Highly Durable and High-Functional Concrete Satisfying Multi-Component-Blended Cement using Multi-Component Mixed Cement, NA Type--Artificial Composites and New Materials for Performance Improvement , Na Type-Artificial Zeolite and New-materials for Performance Improvement}

The present invention is a renewable energy, such as blast furnace slag powder, coal ash and silica fume, which has been abundant in order to greatly reduce CO ₂ generated in ordinary Portland cement, reduce heat of hydration of concrete, suppress alkali-aggregate reaction, and greatly improve durability. Multi-component mixed cement, slag aggregate, Na-artificial zeolite, metakaolin and reinforcing hydrophilic nylon short fiber, PVA short fiber and PE short fiber new material using effective recycling It relates to a method for producing high functional concrete.

With the recent expansion of national infrastructure, high-rise buildings, and large-scaled buildings, the demand for cement, which is used as the main material for construction works, is increasing rapidly, but the cement industry generates large amounts of CO ₂ , a major factor in global warming. . In other words, the cement is powdered by mixing SiO ₂ (silica), Al ₂ O ₃ (alumina) and CaO (lime) and adding an appropriate amount of CaSO ₄ · 2H ₂ O (gypsum) to a clinker that is partially melted and sintered. Since the clinker must be melted at a high temperature of about 1,450 ° C., a large amount of energy is consumed, which causes about 1 ton of CO ₂ to produce ₁ ton of cement.

In order to solve these problems, the development of highly durable high-performance concrete to suppress the generation of hydration heat, chemical resistance and deterioration of concrete caused by using renewable energy with small CO ₂ as a binder and using cement And the development of applied technology is urgently required in the construction industry, where the demand for cement is the greatest.

In addition, more than 6 million tons of coal ash are being produced per year in coal-fired power plants due to the recent increase in national infrastructure, industrial facilities, high-rise buildings and plant expansion. As the production of slag increases, the treatment cost increases and environmental pollution is intensifying. The manufacturing technology of eco-friendly and high-performance concrete for restoration of hydrophilic environment using multi-component mixed cement using characteristics of renewable energy such as blast furnace slag powder and coal ash, which are industrial by-products Development is a national challenge.

On the other hand, 'environmentally friendly vegetation concrete mixed with steelmaking slag fine powder', which is made of fine steelmaking slag powder as a substitute for cement, suppresses alkali moisture and provides SiO ₂ , Fe, P ₂ O ₅ components to improve plant growth. Although the block '(KR 10-0521142 B1) has been published, steelmaking slag contains free lime CaO (free-CaO or F-CaO), which is in contact with water and causes expansion. Therefore, since aging treatment to eliminate latent expansion is essential, there is a problem in that it is time consuming and economical, and there is a problem in that it cannot be a complete aging treatment, which may shorten the life of concrete.

In addition, wastewater recycled aggregate and Fe-type zeolite using 'eco-friendly concrete for water purification using recycled aggregates' (KR 10-0508881 B1) and 'microbial water' (KR 10-0840602 B1) has been registered. The above technologies have positive aspects of resource recycling by using recycled aggregate and waste concrete, but there is a problem of deterioration of harmful substances or aggregates contained in itself, and in case of using Fe-zeolite, The domestic development and production is insufficient, and it is not practical to use due to the restriction of use and the increase of manufacturing cost. The cultivation of a large number of useful microorganisms and mixing them into concrete also have a weak ability to decompose and remove polluted water and harmful substances, and the alkali in concrete Dilution of growth of useful microorganisms due to elution, etc. and difficulty in field application.

In addition, polypropylene fiber used for reinforcement in the existing 'environmentally friendly plant-type block using charcoal powder and recycled aggregates' (KR 10-0822061 B1) has low reinforcement effect due to its non-hydrophilicity, so it is peeled off when used in concrete. Problems such as phenomena, breakdown of connecting parts and connecting parts, and improvement of physical properties that are insufficient to secure durability life, and enormous human and property damages due to deterioration of infrastructure, loss and deterioration of water conversion due to heavy rain due to warming, etc. Decreases. In addition, the production and utilization of eco-friendly, high-performance concrete for the construction of a hydrophilic environment, which is structurally stable and has excellent greening, water purification and pollution reduction functions, and has excellent protection and disaster prevention functions, will be achieved through the present invention. It is expected to be able to provide inventions that can greatly contribute to industrial development.

Table 6 below shows the measurement results of the quality characteristics of eco-friendly, high-performance concrete for hydrophilic environment restoration using multi-component mixed cements, artificial zeolites, and new performance-enhancing fiber materials for Comparative Examples and Examples (Tables 1, 2, and 3). will be.

[Table 6] Quality Characteristics of High Functional Concrete

Table 7 below shows the measurement results of the quality characteristics of the eco-friendly high-performance concrete for hydrophilic environment restoration using the multi-component mixed cement and the performance-enhancing fiber new material for Comparative Examples and Examples (Tables 4 and 5).

[Table 7] Quality Characteristics of High Performance Concrete

Examining the quality characteristics test results for the examples, the porosity tended to decrease with increasing the mixing ratio of the multicomponent cements at the same aggregate particle size, which means that the blast furnace slag powder, fly ash and silica fume It is believed to be due to the relatively increased binder at the same water-binder (multicomponent mixed cement composition) ratio because it is usually less than the density of portland cement. In addition, Na-type Artificial Zeolite, Advanced Fiber and porosity in the case of mixing the meta-kaolin is exhibited a tendency to slightly decrease, which is Na-form - using the addition of Artificial Zeolite and Advanced Fiber to the volume ratio of the concrete unit volume (1m ³⁾ In addition, it is considered that the pores formed inside the composite were filled by incorporating metakaolin at a mass ratio to the binder. In addition, when Na- artificial Zeolite and new fiber materials are mixed in an appropriate amount, the porosity decreases slightly, the compressive strength and the flexural strength are increased, and unexpected results are obtained with excellent effects in both freeze-thawing resistance and impact resistance. there was.

It was shown that the measured porosity of all the above examples showed only a difference within about ± 2.5% from the designed porosity, which was originally aimed at the blended design, to satisfy all the design target porosities.

The compressive strength characteristics showed better compressive strength characteristics when the aggregate particle size was smaller at the same target porosity.These strength characteristics indicate that the smaller the aggregate particle size, the contact number and ground area of the aggregate coated with cement paste formed within a certain volume. This may be due to the increased resistance to external stress and stress dispersion area at load load for strength test. In addition, when the blast furnace slag fine powder (30Wt.%) And fly ash (10Wt.%) Were mixed as in the 110th formulation of the example, the comparative example No. 1 formulation containing only ordinary Portland cement with a compressive strength of 13.2 MPa of 4 weeks old Compressive strength of 4 weeks: 13.3 MPa) was almost the same, and at 8 weeks of age, it was 16.0 MPa, which showed better strength than that of ordinary portland cement alone, and blast furnace slag powder and fly ash were added to the binder (multicomponent mixed cement composition). When mixed in 50% by mass ratio, the strengths were similar or equivalent. The reason for this is that the hydration reaction in ordinary Portland cement and mixed water decreases as the blast furnace slag fine powder and fly ash are mixed, and thus the strength of initial (age 1 week) decreases. Due to the pozzolanic reaction, strength was expressed above the equivalent level. On the other hand, when silica fume is used, the powder density is much higher than that of ordinary portland cement, so that the self-rigidity of the paste is increased, the bonding strength between aggregate and cement paste due to the microfiller effect, and the relative amount of binder material due to the difference in density between ordinary portland cement is increased. It was confirmed that the strength of the binder was improved by increasing.

On the other hand, the relationship between the compressive stress and the compressive strain of the functional concrete by mixing the fiber new material (Nylon fiber, PVA fiber, PE fiber or Hybrid fiber) is as shown in FIG. Looking at this, by incorporating the fiber new material than ordinary porous concrete without mixing the new fiber material, the loss of strength due to the increase in the compressive strain is smaller, it can be seen that the induced fiber induced ductile fracture and increased fracture toughness. . In addition, it is possible to reduce the target porosity by incorporating concrete aggregate or slag aggregate into the porous concrete, and the compressive strength is greatly increased due to the decrease in porosity, and the compressive strength is improved even when Na-artificial Zeolite, a performance enhancing factor, is added. It became.

As a result of examining the bending strength test results for the examples, the tendency of bending strength by mixing blast furnace slag powder and fly ash was similar to that of compressive strength, and the addition of silica fume slightly increased the bending strength. Nylon fiber (length: 19mm, tensile strength: 890MPa, elastic modulus: 7.5GPa), PVA fiber (length: 6mm, tensile strength: 1,560MPa, elastic modulus: 39.0GPa) and PE fiber (length: 12mm) The tensile strength of 2,600 MPa and the modulus of elasticity of 88 GPa were slightly better than those of the new fiber (Nylon fiber, PVA fiber, PE fiber or hybrid fiber). The reason for this is that the new fiber material is used to increase the toughness and crack resistance of the concrete itself. By using metakaolin at the same time, the adhesion and bonding strength of cement paste and high-elastic fiber is increased according to the filling of the fiber gap. The improved properties showed the effect of increasing the flexural strength.

Analysis of the results of the freeze-thaw resistance test for the examples showed that the freeze-thaw resistance was higher than normal in all the examples, and excellent freezing when incorporating fibrous new material (Nylon fiber, PVA fiber, PE fiber or Hybrid fiber) and metakaolin Melting resistance was shown. In addition, incorporation of reinforcing elements also showed better freeze-thawing resistance than that of ordinary portland cement. This tendency is due to the incorporation of high-strength and high-elastic fibrous materials with concrete, which increases the binding force and tensile strength in the concrete structure and prevents segregation and paste dropout by freezing and thawing, as well as metakaolin. It is believed that this is because the bonding force between the aggregate and the cement paste is increased with the mixing.

Considering the results of the chemical resistance test of the examples, the chemical resistance of the multi-component mixed cements and the performance-enhancing fiber new materials (Nylon fiber, PVA fiber, PE fiber or Hybrid fiber) and metakaolin at all aggregate particle sizes and aggregate conditions were measured. There was a tendency to increase somewhat. This cause is due to the use of high toughness and high elastic fibrous new material, which improves the binding capacity and chemical resistance of the 3D randomly dispersed fiber new material inside the concrete, and the internal matrix of cement paste using metakaolin. As the structure becomes dense and the amount of binder is relatively increased, the resistance to deterioration of various chemicals contained in sulfuric acid is improved, and the binder is mixed with fine blast furnace slag powder, fly ash and silica fume, which have high chemical resistance. It is believed that the chemical resistance of high performance concrete is improved due to the large resistance to chemicals.

Considering the results of the impact resistance test of the examples, there was little effect of the mixing of blast furnace slag powder and fly ash, and the new materials (fiber new materials (Nylon fiber, PVA fiber, PE fiber or Hybrid fiber) and silica fume and performance improvement) As the metakaolin} was incorporated, the impact resistance tended to be greatly improved. This is due to the use of high toughness and high elastic fibrous new materials, which improves the binding capacity of the three-dimensional randomly dispersed fibrous new materials inside the concrete, reduces the impact by external forces, and greatly increases the impact resistance by absorbing the impact energy inside the matrix. It seems to be. In addition, as the target porosity and aggregate particle size increased, the impact resistance decreased slightly, which was confirmed to be similar to the tendency of the strength characteristics.

The following Table 8 shows the drying of eco-friendly high-performance concrete for restoration of hydrophilic environment using multicomponent mixed cement, Na-type zeolite, and new performance enhancing fiber materials for Comparative Examples and Examples (Tables 1, 3, 4 and 5). The result is shrinkage and wear resistance.

[Table 8] Dry Shrinkage and Wear Resistance of High Performance Concrete

In order to evaluate the dry shrinkage characteristics of eco-friendly high-performance concrete for restoration of hydrophilic environment according to the present invention, a specimen of 100 × 100 × 400 mm was produced and used in the comparator method of ASTM C 157 and KS F 2424 『Motar and Concrete Length Test Method』. was determined according to change in length due to shrinkage of the specimen up to six months of age, the aggregate test Los Angeles is the steel balls 47.5mm in diameter abrasion tester to evaluate the abrasion characteristics (weight: 438g) the 6 into each φ 100 × 63.5 A specimen of mm was prepared and rotated up to 300 times to measure the mass reduction rate of the specimen.

The results of this study showed that when nylon fiber, PVA fiber, PE fiber or Hybrid fiber, which is a new fiber material, dry shrinkage was reduced by about 15.7 ~ 20.4% compared with the case where no new fiber material was mixed, and the mass reduction rate due to concrete wear was decreased. It decreased by about 7.2 ~ 9.4%. The reason for this is that as the fiber material is mixed, deformation due to dry shrinkage is suppressed due to improved adhesion of the matrix and compactness of the internal structure, and the resistance to cracking caused by impact energy generated during abrasion resistance test is improved. The decrease is believed to decrease. In addition, the amount of dry shrinkage and mass loss decreased with the use of multicomponent cements. When 30% of Na-artificial zeolite (powder or granular), which is a performance enhancing factor, was mixed, the amount of dry shrinkage The mass reduction rate was found to be the best.

The following Table 9 shows the results of measuring the plant growth capacity of the highly durable high-performance concrete using a multi-component mixed cement for Comparative Examples and Examples (Table 1).

[Table 9] Plant Growth Capacity of High Performance Concrete

500 × 500 × 100mm panel type manufactured by the present invention for evaluating the plant growth characteristics of highly durable high-functional concrete using multicomponent cements according to the present invention, Na type-artificial zeolites and new performance enhancing fiber materials Test specimens for performance evaluation were prepared by filling the interior voids with water, fertilizers, and cultured soils, and mixing the cultured soils and pitmouths on the top of the block to carry out the cover soil. Perennial Ryegrass, a herbaceous plant, and Nangnacho, a tree species. Sowing was observed by measuring the growth state of each age to measure the length of the grass.

The results of this study show that when the blast furnace slag powder is mixed, the mixing volume of ordinary portland cement decreases and the height of the grass grows regardless of the type of seeding due to nutrients (iron, carbon, etc.) eluted from the blast furnace slag powder. At 90 days of age, the plant length was 32.7 ~ 38.1cm for herbaceous plants and 10.8 ~ 14.3cm for herbaceous plants. Therefore, when the high-performance concrete prepared by the present invention is applied as a product for repair structure, it is possible not only to reduce CO ₂ , which is a major cause of global warming, but also to activate various plants, and to harmonize with the surrounding natural ecosystem and The effect of creating a hydrophilic environment can be obtained.

Table 10 shows the results of water purification characteristics of high-durability high-performance concrete using multi-component mixed cement, Na-type Zeolite, and new performance-enhancing fiber materials for Comparative Examples and Examples (Tables 1, 3, and 4). It is shown.

[Table 10] Water Purification Characteristics of High Performance Concrete (Measured on Age 14)

The water-purification characteristics of the highly durable high-functional concrete using the multi-component mixed cement, Na-artificial Zeolite and the performance-enhancing fibrous material produced by the present invention, Na-artificial under the same aggregate granularity and target porosity The incorporation of zeolite (powder or granular) tended to significantly increase both the TN and TP scavenging rates. In the case of TN, the scavenging rate was improved to 20.7 to 26.2%. Up to 91.4%.

This Na- artificial Zeolite maximizes the effect of water purification by microorganisms that induce the ion exchange reaction with harmful substances such as PO ₄ ^{3 -} as shown in FIG. 6 and inhabit the continuous porosity of the porous concrete. In addition to the CEC (Cation Exchange Capacity), the adsorption of harmful substances and catalytic activity have been shown to increase the removal rate of TN and TP. In addition, the BOD and COD scavenging rate increased with TN and TP similarly with Na type artificial zeolite, and improved by up to 29.8% and 33.4%, respectively. The erase rate and the TP erase rate increase. On the other hand, ordinary Portland cement 342kg / m ³ , unit quantity of 171kg / m ³ , aggregate particle size of 5-25mm crushed stone 1,057kg / m ³ , concrete aggregate aggregate 724kg / m ³ , high performance AE water reducer 0.34kg / m ^In the case of ordinary concrete with 3% porosity by mixing ³ , the removal rate of BOD and COD was 5.5% and 5.1%, respectively, while the continuous porosity was formed to 15% using bicomponent mixed cement and new short fiber material. In Example 401, the BOD and COD scavenging rates were 35.7% and 32.4%, respectively. On the other hand, the soil stabilization by neutralization, sludge reforming and moisturizing function of acid rain and acid soil by adsorption of harmful substances and cation exchange function on the ground around high-functional concrete structures.

Test results of the adiabatic temperature rise by the hydration reaction of concrete using the multi-component mixed cement are as shown in FIG. Looking at this, compared to the concrete using only Portland cement only, the concrete mixed with the multi-component mixed cement prepared by the present invention was found to be delayed in the hydration smoke time and the thermal insulation temperature of the concrete was about 13 ℃ lower maximum. This Ca ² of the liquid phase, since the adsorption and Ca ions Ca (OH) to reduce the amount of cement _second generation is reduced fly ash is then Al ions eluted in the liquid is in contact with water By mixing the blast furnace slag and fly ash ^{+ The} concentration is kept low, delaying the initial hydration reaction and lowering the adiabatic temperature. In addition, as a result of measuring the penetration resistance of chloride ions in concrete using multicomponent cements (OPC: SG: FA = 6: 3: 1), when only ordinary Portland cement was used, it was 5,230 (Coulomb) at 4 weeks of age, and 3,980 at 12 weeks of age. The total through charge of Coulomb) was shown, whereas the total through charge of 2,650 (Coulomb) at 4 weeks of age and 924 (Coulomb) at 4 weeks of age was shown. Long-term age was found to be very effective in increasing flame resistance.

On the other hand, blast furnace slag powder has latent hydraulic properties (creating CSH gel with alkali in cement), and has characteristics such as long-term strength, water tightness of concrete, salt shielding, and suppression of alkali aggregate reaction at high temperatures, but the thermal insulation temperature rise is accelerated by high temperature. The fly ash may increase the dry shrinkage, and fly ash improves fluidity due to the pozzolanic reaction (CSH gel formation) and ball bearing effect, and greatly improves physical properties and water-tightness by reducing the amount of unit, but the initial strength is greatly decreased. Silica fume has the effect of reducing the bleeding and improving the viscosity due to pozzolanic reaction (CSH gel formation) and micro filler effect.In particular, silica fume has a very high powderiness, but improves strength, permeability, sulfate resistance and freeze-thawing resistance. Because of the fineness, a combination of many mixed waters or high-performance sensitizers is essential to obtain a given workability.

As described above, the mineral admixture reacts with Ca (OH) ₂ , which is a primary hydrate produced by cement hydration, to produce calcium silicate hydrate and calcium aluminate hydrate. However, special care needs to be taken in the use of each mineral admixture, and materials should be selected according to their properties and properties. Therefore, the mixed cement used in the present invention is a complementary form of these properties by using a specific ratio for the binder that can emphasize only the advantages of each admixture, reducing CO ₂ and recycling renewable energy and long-term strength, high durability In addition, it is possible to have a hydrophilic environment and an ecological restoration function at the same time by improving workability, reducing heat of hydration and dissolution of nutrients.

From the above results, new fiber (Nylon fiber, PVA fiber, PE fiber or Hybrid fiber) and metakaolin are used to improve the strength and durability of high-performance concrete using multicomponent cements. In order to promote the reduction of environmental pollution, by producing high-strength, high-durability high-performance concrete mixed with Na-artificial Zeolite, it is possible not only to obtain excellent mechanical properties and structural strength, but also to maximize plant growth and water quality improvement. The applicability of concrete to the composition of the environment and the activation of eco-friendly ecosystem was confirmed.
