It relates to a method for producing.

Conductive concrete is a concrete having characteristics such as excellent electrical conductivity, high strength, high durability and excellent workability, and can be used for cement concrete products for reducing ground resistance, antistatic, heat generation, and electromagnetic wave shielding.

Until now, conductive concrete products have been mixed with cement and heat-treated petroleum coke as a conductive material (Marconite, manufactured by Markonite, UK) or carbon fiber [DODENCRETE, Japan chemistry company Product] is mainly used, but the addition of heat-treated petroleum coke as a conductive material has a limit on the effect of reducing resistance, and the carbon fiber has a high unit cost of materials and it is difficult to mix the material with cement. As a conductive material, cement is mixed with graphite such as soil graphite, phosphate, etc., by controlling the particle size, and fluidizing agent is added to control the mixing property. Although conductive concrete compositions have been developed to secure the properties, cement By using it, there was a disadvantage that it could not pollute the surrounding environment or obtain satisfactory electrical conductivity and strength.

On the other hand, the conventional technique for lowering the ground resistance is to reduce the earth resistivity by spraying salt water or filling the charcoal powder near the ground electrode of the pole pole, communication pole, but the salt spraying method is a temporary effect, but rain water Disappear by groundwater flow, etc., continuous effects cannot be expected, and the method of filling charcoal causes the electrodes to erode, and in the worst case, the ground wire may be disconnected.

In addition, in order to reduce the ground resistance, the earth resistivity was lowered or the contact area of the electrode was expanded. A chemical reducing agent was used. However, when the chemical reducing agent is mixed with water and embedded around the ground electrode, the gel contains moisture. Initially, there is an effect of lowering the ground resistance, which is lost by rainwater or groundwater flow in a relatively short time (months to a year) and loses its function, thereby causing soil pollution. Have occurred, there is a problem that can not play the role of grounding to send lightning and the like to the ground.

Mineral powder in the binder composition for conductive concrete is C 5 ~ 81.7%, O 20 ~ 86.7%, Mg 1 ~ 67.7%, Al 1 ~ 67.7%, Si 3 ~ 69.7%, S 0.5 ~ 67.2%, Cl 0.5 ~ 67.2 Those having an element composition ratio of%, Ca 2-68.7%, Ti 0.1-66.8%, Mn 0.05-66.75%, Fe 0.05-66.75% and In 0.1-66.8% are used.

It is preferable to use a mineral powder that does not contain heavy metals that harms the human body, and may contain trace elements in addition to the above components, and some of the above components do not contain or are substituted with other components. Also available. In addition, the elemental composition ratio of the mineral powder is not particularly limited, but C, O, Mg, Al, Si, S, Cl, and Ca must be included, and although the function of each element is not clearly identified, the above elements When each of these is not contained, the effect by this invention cannot be acquired.

The mineral material is effective to use a particle size of 200 ~ 325 mesh (mesh), when the particle size is less than 200 mesh, there is a problem that the strength of the conductive concrete to be manufactured is not satisfactory, and when it exceeds 325 mesh It is not economical because manufacturing costs are rising.

Meanwhile, alkali metal chlorides and alkaline earth metal chlorides refer to chlorides of Li, Na, K, Rb, Cs, Si, Al, Fe, Ca, Na, K, and Mg, and at least one of them should be used. Chloride and alkaline earth metal chlorides form a colloidal solution of mineral particles by surface-active enzyme and clustered water, and the colloidal solution formed functions as a binder by binding to minerals of mineral powder.

In addition, surface-active enzyme binds to hydrophilic enzyme surface to show amphiphilic by combining hydrophobic polymer with alkali metal chloride and alkaline earth metal. It is effective to support the activation of the chloride, it is effective to use the amount of 0.1 to 3% by weight based on the weight of the clustered water, when the amount of the surfactant is less than 0.1% by weight relative to the weight of the clustered water There is a disadvantage that the activation of the alkali metal chloride and alkaline earth metal chloride is weak, there is a problem that is not economical when it exceeds 3% by weight.

In addition, the clustered water may be prepared using the methods described in US Pat. Nos. 5,711,950 and 6,033,678, and there is a problem in that the colloidal solution prepared is not stabilized when non-clustered water is used.

At least one compound selected from the group consisting of alkali metal chlorides and alkaline earth metal chlorides is added to and dissolved in a mixture of clustered water and surfactant. At this time, the amount of the at least one compound selected from the group consisting of alkali metal chlorides and alkaline earth metal chlorides is effective to use the amount of 1 to 60% by weight based on the weight of the clustered water, alkali metal chloride and alkaline earth metal When at least one or more compounds selected from the group consisting of chlorides are used in less than 1% by weight, there is a disadvantage in that the binding strength with mineral components derived from the mineral powder is lowered. Weak

A liquid binder is prepared in which water containing a small amount of rare earth elements and a pH adjusting agent are mixed in a solution in which an alkali metal and / or alkaline earth metal chloride is dissolved in a mixture of surfactant and clustered water.

Rare earth elements include lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, turlium, yttbium, ruthenium, scandium, yttrium, etc. Also available. Water containing a small amount of rare earth elements functions as an adjuvant of alkali metals and / or alkaline earth metal chlorides, and at the same time, functions to easily combine minerals and colloidal solutions by sterilization and bacteriostatic action. The content of the rare earth element is effective to use less than 1% by weight based on the total weight of the clustered water, and even in the water containing the rare earth element, water is used as the clustered water.

On the other hand, by using a pH adjuster in the liquid binder to be prepared to make the pH of the product to be weakly alkaline, the amount of the pH adjuster can be appropriately adjusted according to the required pH.

The liquid binder and the mineral powder prepared as described above are mixed in amounts of 10 to 90% by weight, respectively, to prepare a binder composition for conductive concrete. If the liquid binder is less than 10% by weight or the mineral powder is more than 90% by weight, the strength of the conductive concrete produced is low, the curing time is long, there is a disadvantage that the liquid binder is more than 90% by weight or mineral When the powder is less than 10% by weight, the strength of the conductive concrete is improved, but there is a problem in that casting and hardening of the concrete is not easy.

When the liquid binder and the mineral powder are mixed, the condensation and hardening occur rapidly, so it is preferable to mix the liquid just before using it as concrete.

It is effective to use 30 to 90% by weight of the binder is configured as described above with respect to the total concrete composition, when the amount of the binder is less than 30% by weight has a disadvantage of weak strength of the hardened concrete after pouring, 90 weight When it exceeds%, the workability of concrete is not satisfactory and it takes a long time to harden, and it is not economically desirable because the amount of the concrete main material is insufficient to use a relatively large amount of binder.

Minerals used in the present invention may be used in combination of one or two or more selected from the group consisting of elite, zeolite, bentonite, tourmaline, montmorillonite.

The illite is a monoclinic mineral belonging to the monoclinic system, having a hardness of 1 to 2, specific gravity of 2.6 to 2.9, streaked color of white, and chemical composition of (K, H ₃ O) Al ₂ (Si, Al) ₄ O ₁₀ (H ₂ O, OH) ₂ . In terms of chemical composition, some are close to dolomite, but relatively high in SiO ₂ , MgO, H ₂ O, and low in K ₂ O, and are produced in aluminium-rich heterogeneous or tuff sedimentary rocks. Calculated as an altered mineral of aqueous gneiss.

Zeolite is a generic term for minerals that are aluminum silicate hydrates of alkali and alkaline earth metals. Colors are colorless, transparent or white translucent, and are also called zeolites. Hardness does not exceed 6, specific gravity is about 2.2, and the main types are boulderstone, fisheye stone, caberite, soda-stone, hydrandite, steel bite, lomontite, and insite, and basic igneous rocks such as basalt and whirlwind. Produced in the cavity of or in the thermosphere, sometimes as a secondary mineral in granite and gneiss.

In addition, it is sometimes produced in gold or other veins, and the structure of each atom is loose in crystal structure, and even though the moisture filling the space is released at high heat, the skeleton remains the same so that other fine substances can be adsorbed. It is used as an adsorbent and is also used as a molecular sieve to separate particulates of different sizes.

Bentonite is a clay mainly containing montmorillonite, a mineral belonging to the monoclinic system having a crystalline structure like mica, and its color is white, gray, light brown, light green, etc., and it is found in casting type binder, ceramic raw material mixing agent, and base of ointment.

Tourmaline is a borosilicate with hexagonal columnar crystals. It is a natural mineral belonging to the hexagonal system and has permanent electrical properties. The anions, weak currents, and far infrared rays are found to be useful for health and the environment. Electrostatics continue to generate because the electrons are constantly coming in from the sun, but the electrons have cations and anions, but the cations called plotons do not pass through the earth's atmosphere and only pass negative ions in the solar wind. It is absorbed by the positive electrode and transported to the minus pole, and naturally anion electrons are pushed out of the negative electrode side, which is protruded along the electric field line of the positive electrode and becomes a permanent flow of electricity, which is a weak current of 0.06 mA. Human body Is the most suitable current for. Tourmaline crystals continue to generate weak currents, so they continue to generate negative ions and far infrared rays.

Montmorillonite is a monoclinic mineral that is a kind of clay mineral. It has hardness 1 ~ 1.5, specific gravity 2 ~ 1.5, white, gray, pink, blue, green, and absorbs moisture to increase the volume 7 to 10 times. It has high ion exchangeability, has a tackiness at water content of 150% to 500%, has a small internal friction resistance, and is produced by alteration of mineral-rich minerals or rocks.The chemical composition is (Al, Mg ) ₂ Si ₄ O ₁₀ (OH) ₂ .4H ₂ O.

The mineral used in the present invention is not only used as the main material of the conductive concrete together with the blast furnace slag or converter slag, but also serves to assist the function of the mineral powder which is part of the main material of the binder, and uses 2 to 62% by weight based on the total concrete composition. When the amount of minerals used is less than 2% by weight, the workability of concrete is not satisfactory, and it takes a long time to harden, and when it exceeds 62% by weight, a relatively small amount of binder As it is used, the strength of the hardened concrete after pouring is weak, which is undesirable.

On the other hand, the slag used in the present invention can be used alone or in combination with the blast furnace slag or converter slag, it is preferably used in terms of waste recycling, but may be replaced with the one corresponding to the small aggregate of the material of the concrete, When slag is manufactured in the blast furnace, converter slag is produced as a by-product in the converter, although not particularly limited, it is preferable to use a high powder (Blaine), and when using a low powder, conductive concrete There is a problem in long-term stability due to cracks in the strength decreases with age.

The slag plays the role of aggregate in the conductive concrete of the present invention, it is effective to use 6 to 66% by weight based on the total concrete composition, when the amount of slag used is less than 6% by weight is not satisfactory workability of the concrete There is a disadvantage in that it takes a long time to cure, and if it exceeds 66% by weight, since the relatively small amount of binder is used, the strength of the hardened concrete after pouring is not preferable.

In addition, in order to give conductivity to concrete in the present invention, at least one or more of 2 to 62% by weight of a conductive material composed of carbon fiber, conductive graphite, conductive filler, and carbon nanotube (CNT) is used.

The carbon fiber is a fiber made by heating and carbonizing an organic fiber in an inert gas, and as a raw material, cellulose, acrylic fiber, vinylon, pitch, etc. are used, and the molecular arrangement and crystal change depending on the raw material or the processing temperature. Occurs. In general, hexagonal rings of carbon form a layered lattice successively, have a metallic luster, black or gray color, and have a strength of 10 to 20 g / d and specific gravity of 1.5 to 2.1. Excellent heat resistance and impact resistance, resistant to chemicals and high resistance to pests. Molecular weights such as oxygen, hydrogen, nitrogen, etc. are lost during the heating process, and thus the weight is reduced. Due to these characteristics, sporting goods (fishing rods, golf clubs, tennis rackets), aerospace industry (heat-resistant materials, aircraft fuselage), automobiles, civil construction (light materials, interior materials), electrical and electronics, telecommunications (antenna), environmental industry (air purifier) It is widely used as a high performance industrial material in each field.

In addition, although the conductive graphite utilizes the excellent electrical conductivity of the graphite, it has a disadvantage in that the electrical conductivity is not satisfactory compared to other materials, and thus must be used in a large amount.

In addition, a conductive filler commonly used in the art may be used.

Carbon nanotubes are hexagonal materials consisting of six carbons connected to each other to form a tubular shape, and the diameter of the tube is only tens to tens of nanometers, which is called carbon nanotubes, and its electrical conductivity is similar to that of copper. Is the best diamond in nature, with 100 times the strength of steel, carbon fiber breaks with only 1% strain, while carbon nanotubes can withstand 15% strain, and semiconductors, flat panel displays, batteries, and superpowers. Numerous devices using carbon nanotubes such as fibers, biosensors and television CRTs have been developed.

In general, the carbon nanotube has an arm-chair structure in the present invention because the carbon nanotube has a characteristic of exhibiting conductivity in the arm-chair structure and semi-conductivity in the zig-zag structure. use.

In the present invention, it is effective to use 2 to 62% by weight of the conductive material with respect to the entire concrete composition, and when the amount of the conductive material is less than 2% by weight, the conductivity of the manufactured conductive concrete is not satisfactory. If the weight percentage is exceeded, there is a problem that the cost is excessively increased.

The materials of the conductive concrete of the present invention have a significant difference in density, and since they are heterogeneous materials and are not easily mixed, the remaining materials except the binder are mixed in the solid state, and then the binder is mixed.

The conductive concrete of the present invention is most preferably composed of 60% by weight binder, 10% by weight mineral, 20% by weight slag and 10% by weight conductive material.
